Повний текст джерелаMADS-box transcription factors (TF) have been mostly characterized for their involvement of plant development such as floral organogenesis and flowering time. Some of them are involved in stress related developmental processes such as abscission, fruit ripening and senescence. Overexpression of the rice OsMADS26 TF suggested a function in stress response. Here we report that OsMADS26 interfered lines presented a better resistance against two major pathogens of rice, Xanthomonas oryzae (Xoo) and Magnaportae oryzae (Mo) and a better recovery capacity after a water stress period. Transcriptome analysis revealed that several biotic and abiotic stresses related genes were up regulated in OsMADS26 interfered lines. In addition QPCR analysis showed that the expression of a set of biotic and abiotic genes was induced when OsMADS26 interfered lines were infected by Xoo or submitted to a water stress. This indicated that OsMADS26 is a negative regulator of biotic and abiotic stress response in rice. Taking in account the data previously published that showed that inducible overexpression of OsMADS26 resulted in the activation of expression of genes involved in jasmonic acid or reactive oxygen species biosynthesis, we postulate that OsMADS26 may be a hub regulator of stress response in rice and that it may be posttranscriptional regulated to modulate negatively or positively rice response to various stresses.In addition we have shown in this thesis that an insertion mutant line disrupting the OsMADS25 gene is characterized by a reduced number of tiller. This phenotype was also obtained in transgenic lines expressing the OsMADS25 transcription factor fused with a dominant motif inhibitor of transcription. Thissuggested that OsMADS25 is involved in the control of tiller development in rice.Key words: Rice, stress, blast, tillering, MADS-box, transcription factor, OsMADS26, OsMADS25, transcriptome

M52048, a T-DNA insertion mutant, shows dwarf, early flowering, node bending and impaired in panicle exsertion and it has been demonstrated to have three flanking genes OsMADS14, OsMADS34 and OsCP7 activated. Transgenic plants, Ubi:OsMADS14, ectopically overexpressing OsMADS14 revealed dwarf and early flowering phenotype, and up-regulated expression of florigen genes Hd3a and RFT1 were observed in the previous study. The first part of this study is to investigate the possible mechanisms that how the expression of Hd3a and RFT1 can be up-regulated by OsMADS14. At first, the expression profile of rice florigen regulators such as OsPRR37, OsCO3, DTH2, OsDof12, PPS and RFL were analyzed. Among them, the expression of RFL was promoted and OsCO3 was repressed suggesting that the activation of Hd3a and RFT1 might result from the up-regulation of RFL and/or down-regulation of OsCO3. Secondly, the phase transition miRNAs, miR156 and miR172 were investigated and results showed the expression of miR156 was slightly activated while miR172 was repressed suggesting that the delayed phase transition might occurred in Ubi:OsMADS14. Thirdly, the expression of potential floral repressors such as putative OsTOE1 (TARGET OF EAT1), putative OsTEM1 (OsTEMPRANILLO1), putative OsTEM2 and RCN1 that may regulate by OsMADS14 were analyzed. Results showed that OsTEM1 and RCN1 were activated, suggesting the possible involvement of partial counteraction of the effect of early flowering by OsMADS14. Finally, physiological functions of these putative floral repressors were studied by investigating their correspondent T-DNA insertion activation mutants such as M59289 (for OsTOE1), M78020 (for RCN1) and M89461 (for OsTEM1). Among these mutants, only the putative OsTEM1 gene in mutant M89461 was activated and a slightly late flowering phenotype was observed in mutant M89461 as well suggesting that the putative OsTEM1 might be a floral repressor in rice. Transgenic plants, Ubi:OsMADS34, ectopically overexpressing OsMADS34 revealed impaired panicle exsertion phenotype and that resulted by the reduced length of the first internode was previously demonstrated. The second part of this study is to investigate the possible mechanisms that how the length of the first internode was significant reduced by overexpressing OsMADS34. Results of the microarray assays comparing Ubi:OsMADS34 to TNG67 revealed differential expressed of many stress-related genes. Among them, 31 genes designated as M1 to M31 were selected for further study and their expressions were to be confirmed by RT-PCR. Results showed that the expression profile of M1, M2, M4, M8, M9, M10, M16, M17, M18, M21, M22, M23, M24, M26, M27, M30 and M31 were in accordance with the results of microarray assays suggesting that the expression of these genes were regulated by overexpression of OsMADS34.

A rice T-DNA insertion mutant M0052048 showing extreme early flowering, bending tillers and impairment in panicle exertion was isolated from the Taiwan Rice Insertion Mutant (TRIM) library. This mutant contained a copy of the T-DNA tag inserted in the chromosome number 3 at the 64,867 bp position of OSJBa0032E21 BAC clone where the expression of 048-3 (OsMADS34), 048-4 (OsMADS14) and 048-7 (putative cysteine proteinase, OsCP7) genes were activated by the 35S enhancer located in the T-DNA. The OsMADS14 and OsMADS34 are MADS box-containing transcription factors that have important roles in plant growth and development and furthermore, OsCP7 is a putative cysteine proteinase that may be involved in the program cell death, pollen and xylem maturation, embryogenesis and flowering time in plants. In order to understand the functions of these activated genes and their contribution to the mutant phenotype, transgenic rice over-expressing each of these genes were created and expression profiles of these genes in various rice plant tissues were analyzed. RT-PCR analysis revealed that OsMADS14 and OsMADS34 expressed mainly in panicles but not necessarily in vegetative tissues, with the exception of a relatively high expression level of OsMADS14 in the 90-day-old leaf; For OsCP7, no clear expression signals were detected in all tested tissues. Transgenic rice Ubi:MADS14 showed constitutive expression of OsMADS14 in leaf tissue and revealed extreme early (63.6 days vs 121.3 days in TNG67) flowering and tiller bending phenotypes. The transgenic rice Ubi:MADS34 showed constitutive expression of OsMADS34 and revealed impairment in panicle exertion and slightly early (110 days vs 121.3 days) flowering compared to TNG67. For the overexpression study of OsCP7, no transgenic plant with ubiqutin promoter construct (Ubi:CP7) was obtained, thus a 1.6 kb promoter region from native OsCP7 gene was used to replace the ubiqutin promoter and several ectopically-expressed OsCP7 transgenic rice plants were obtained. These OsCP7 transgenic rice plants showed increased levels of OsCP7 mRNA and protein and higher cysteine protease activity compare to that of TNG67. In addition, these plants had reduced height, approximately 88% of TNG67, and revealed brown lesions on the surfaces of most spikelets that were neither observed in the TNG67 nor in M0052048. In summary, the present study suggests that the activation of OsMADS14 and OsMADS34 genes contributes to early flowering, bending tillers and impairment in panicle exertion phenotypes in the mutant M0052048. However, the effect of OsCP7 activation in mutant M0052048 and the function of OsCP7 in rice plants are still not clear and further investigations will be needed to answer these questions.

The T-DNA mutant M52048 identified from Taiwan Rice Insertional Mutant (TRIM) library showed dwarf, early flowering, node bending and impaired in panicle exertion. Three flanking genes, OsMADS34, OsMADS14 and OsCP7 (putative cysteine protease 7) were activated in this mutant. Both OsMADS34 and OsMADS14 belong to MADS-box gene family that may participate in regulation of flowering time and the identity of floral organ. OsCP7 is a member of C1A cysteine proteases. In this study, the function of OsMADS14 and OsCP7 were further investigated. Previous study has demonstrated that over-expression of OsMADS14 could cause early flowering. To understand whether or not any other flowering regulatory genes were affected by the expression of OsMADS14. The flowering regulatory genes including OsGI, OsMADS50, Ehd2, Hd1, Ehd1, Hd3a, RFT1, OsMADS14 and OsMADS18 were investigated in mutant M52048 and Ubi:OsMADS14, Ubi:OsMADS34 and OsCP7:OsCP7 transgenic rice respectively. Results showed two florigen genes, Hd3a and RFT1, expressed much earlier in M52048 and Ubi:OsMADS14 but not in Ubi:OsMADS34 and OsCP7:OsCP7, suggesting that Hd3a and RFT1 were regulated by the expression of OsMADS14. The mechanism how the expression of OsMADS14 could regulate florigen genes requires further investigation. Expression of OsCP7 driven by the maize ubiquitin promoter or the CaMV 35S promoter in transgenic rice cannot be obtained successfully. However transgenic rice, OsCP7:OsCP7 using 1.6 kb of OsCP7 promoter could be easily obtained and OsCP7:OsCP7 transgenic rice plants revealed slightly shorter in plant height, delayed flowering, lower fertility and lesion-like spots on spikelet. In contrast to the wild-type where no OsCP7 was detected in panicles, the RNA and protein expressions of OsCP7 in OsCP7:OsCP7 transgenic rice were detected in leaves at all development stages and panicles, and their expressions in transgenic rice correlated to the observed phenotypes. In addition, the phenotypes of segregated homozygous plants showed more significant than those of heterozygous plants within the same transgenic line, suggesting the dosage effect of transgene. However the expression levels of RNA and protein cannot be differentiated between homo- and hetero-zygous lines. To unravel the causes that lead to lower fertility of OsCP7:OsCP7, the floral organ and pollen viability were investigated. The floral organ showed no obvious differences between wild-type and OsCP7:OsCP7, but the pollen viability of OsCP7:OsCP7 was lower than that of wild-type, indicating that continuing expression of OsCP7 influence pollen development. Further investigation also indicated that the lesion-like spots on spikelet was correlated with the expression levels of OsCP7 and the lesions could possibly due to the programmed cell death caused by the activity of increased mature OsCP7 present in spikelet.

Oncidium is one of the most important orchids used for cut flowers and potted plants in Taiwan. The creation of new cultivars with novel traits is important for Oncidium to enhance the competitiveness of orchid industry. However, traditional breeding processes are limited by the long life cycle and self-incompatibility. The objectives of this study intend to analyze rice AP1-like gene OsMADS14 in Arabidopsis and Oncidium through genetic transformation. In this study, the rice gene OsMADS14 driven by maize ubiqutin promoter was introduced into Arabidopsis and Oncidium Gower Ramsey mediated by Agrobacterium tumefaciens. Twenty one independent ubiquitin::OsMADS14 transgenic Arabidopsis plants were produced, confirmed by PCR and RT-PCR analysis. The ectopic expression of OsMADS14 in transgenic Arabidopsis plants showed dwarf, early flowering and terminal flowers. In addition, the OsMADS14 gene were introduced into Oncidium Gower Ramsey using Agrobacterium tumefaciens-mediated transformation, protocorm-like bodies ( PLBs ) of Oncidium were used as explants materials for genetic transformation and selected on medium containing 5ppm hygromycin. The resistant transgenic Oncidium were analyzed by PCR, RT-PCR and histochemical GUS assay, indicating the transgene integrated into the genome. The resistant transgenic Oncidium showed leave bending phenotype. The results of this study suggest that the rice OsMADS14 gene could be applied early-flowering and dwarf traits to ornamental flowers.

The T-DNA mutant M52048 identified from Taiwan Rice Insertional Mutant (TRIM) library showed dwarf, early flowering, node bending and impaired in panicle exertion. Three flanking genes, OsMADS34, OsMADS14 and OsCP7 (putative cysteine protease 7) were activated in this mutant. Both OsMADS34 and OsMADS14 belong to MADS-box gene family that may participate in regulation of flowering time and the identity of floral organ. OsCP7 encode a putative cysteine protease, belongs to C1A cysteine protease family, its function remains unknown. In this study the function of OsMADS34 and OsCP7 were further investigated. Previous study showed that over-expression of OsMADS34, Ubi:OsMADS34 transgenic rice, could cause slightly early flowering and impaired in panicle exertion. Morphological dissection indicated that the impaired in panicle exertion was mainly caused by shortening the first internode (peduncle). Inhibition of the peduncle elongation caused by drought stress and ABA accumulation has been reported. In the present study, some drought-related genes, such as DREB1A, DREB1E and EATB, were regulated in Ubi:OsMADS34 transgenic rice and therefore hypothesized that the phenotype of transgenic rice may regulated by drought stress or plant hormones. However, treated transgenic rice with ABA inhibitor and/or GA could not improve the peduncle elongation and panicle exertion, suggested that the shortened peduncle and impaired in panicle exertion in Ubi:OsMADS34 transgenic rice might not cause by ABA accumulation. Analysis of GA biosynthesis related genes and the cell elongation promoting genes, at the internodes, revealed high expression levels of EATB, EUI1, GA13ox1, GA20ox2, OsPK1 and lower expression of XTH28, suggested that the shortened internode might due to the imbalance expression of these genes. However the mechanism how these genes involved in internode elongation remain to be elucidated. In addition to the shortened peduncle, the anther development was also affected in Ubi:OsMADS34, suggesting that OsMADS34 function as an E class MADS-box gene may interact with other MADS-box genes to regulate the floral organ development. Further study by searching OsMADS34 interaction proteins will help us to unravel the possible function of OsMADS34. For the study of OsCP7 gene, we were unable to obtained stable transgenic rice lines with constitutive promoter constructs, suggesting that constitutively ectopic expression of OsCP7 might cause lethal. Instead, transgenic lines with a 1.6 kb of OsCP7 promoter construct, OsCP7:OsCP7, were successfully obtained. OsCP7:OsCP7 revealed slightly dwarf, delayed flowering, lesion-like spots on panicles and lower fertility, and these phenotypes are correlated to the expression of OsCP7 gene. The possible mechanisms that cause these aberrant panicle developments were under investigated.
