Abstract (sommario):
A yellow-seeded mutant of reed canarygrass was crossed with normal black-seeded plants and F2 and test-cross populations observed for seed color. Disomic inheritance was postulated with two recessive genes y1 and y2 being responsible for yellow seed color. Black-seeded plants were designated Y1Y1Y2Y2 although in two black-seeded plants one locus appeared heterozygous, i.e. Y1y1Y2Y2, thereby suggesting that the alleles for yellow seed may occur quite frequently in this species.Key words: Reed canarygrass, Phalaris arundinacea L., seed color, disomic inheritance, genetics

Abstract (sommario):
Self incompatibility (SI) in Phalaris coerulescens is gametophytically determined by two unlinked multi allelic loci (S and Z). Neither the S nor Z genes have yet been cloned. As part of a map-based cloning strategy, high-resolution maps of the S and Z regions were generated from distorted segregating populations using RFLP probes from wheat, barley, oat, and Phalaris. The S locus was delimited to 0.26 cM with two boundary markers (Xwg811 and Xpsr168) and cosegregated with Xbm2 and Xbcd762. Xbcd266 was the closest marker linked to Z (0.9 cM). A high level of colinearity in the S and Z regions was found in both self-incompatible and -compatible species. The S locus was localized to the subcentromere region of chromosome 1 and the Z locus to the long arm end of chromosome 2. Several rice BAC clones orthologous to the S and Z locus regions were identified. This opens the possibility of using the rice genome sequence data to generate more closely linked markers and identify SI candidate genes. These results add further support to the conservation of gene order in the S and Z regions of the grass genomes.Key words: Phalaris coerulescens, self-incompatibility, distorted segregation, mapping, map-based cloning, synteny mapping.

Abstract (sommario):
Triazine resistance in a mutant biotype of Phalaris paradoxa is accompanied by changes in the chlorophyll fluorescence induction curve, and by reduced quantum yield for electron transport, indicating altered photosystem II activity. However, light-saturated rates of electron transport in isolated chloroplasts, rates of CO2 uptake in leaves and dry weight production of the triazine resistant biotype, are equal or superior to those of the wild type. A single mutation in the psbA gene, leading to a serine to glycine shift at position 264 of the thylakoid membrane 32 kDa Qв- protein. was found in the herbicide resistant mutant. The results indicate that triazine resistance is not necessarily linked to inferior photosynthetic and growth performance.

Bibliography: leaves 116-144. In Phalaris coerulescens, gametophytic self-incompatibility is under the control of two unlinked genes, S and Z. An incompatible reaction occurs when both S and Z alleles of the pollen are present in the genotype of the recipient stigma. Either pollen grains fail to germinate or pollen tube growth is arrested shortly after contact with the stigma. This study examines the contribution of genes specifically expressed in the male gametophyte to the physiological processes during pollen tube germination and pollen stigma interaction. Among the aims of this study is the isolation of the Z gene.

Abstract (sommario):
One major problem plaguing reed canarygrass (Phalaris arundinacea L.), a high yielding perennial grass, is its poor seed retention. Folded leaf progeny plants from a cross involving a seed-retaining clone were observed in a space-planted nursery. The objectives of this study were to determine whether the folded leaf trait was associated with higher seed retention and other agronomic traits. The inheritance of this trait was also investigated through crosses performed and evaluated in the field and greenhouse. Under solid stand conditions, highly significant differences (p < 0.01) existed between folded and flat leaf polycross progeny entries for heading date and seed retention percentage. Under space-planted conditions folded leaf plants were significantly different (p < 0.05) from flat leaf plants for height, head length, panicle number and growth habit. Widely divergent segregation ratios led to the rejection of the proposed model of inheritance -- disomic inheritance with duplicate gene action.

Abstract (sommario):
The spread of invasive plant species in natural habitats has become a worldwide problem with negative environmental and economic impacts. An increasing number of invasive organisms are responsible for adverse environmental and economic impacts worldwide, including species extinction, crop failures, reduced water supply, and damage to industrial infrastructures (KERCHER et al., 2007). Phalaris arundinacea L. is widespread throughout the world, except Antarctica and Greenland. Center of diversity of this genus is in the Mediterranean. Members of the genus Phalaris occurs in moist habitats from lower to alpine altitudes (ANDERSON, 1997). Phalaris has a plethora of uses. Its most frequent use is as the root wastewater treatment plants. Phalaris grown as feed for livestock and is also used as an ornamental grass. Phalaris have recently received a lot of attention as a new biomass source for the production of renewable energy in USA. In recent years there has been a massive spread of P. arundinacea across North America (currently occurs in 43 states) and Canada (ZEDLER & KERCHER, 2004). Phalaris represents a significant threat to its original wetland vegetation and is classified as a harmful agens in nine state of U.S. states (LAVERGNE & MOLOFSKY, 2004). It is believed that these aggressive population have European origin.

Abstract (sommario):
Self-incompatibility (SI) is an important genetic mechanism to prevent the inbreeding of flowering plants and also an excellent system for studying cell-cell recognition and signal transduction. During evolution, several SI systems have been evolved. A unique SI system widely spreads in the grasses. In the grasses, two unlinked, multi-allelic loci (S and Z) determine SI specificity. A putative self-incompatibility gene (Bm2) was previously cloned. In this study, the role of Bm2 in self-incompatibility was investigated first. The cDNA homologues of Bm2 were sequenced from two pollen-only mutants. The results indicated that Bm2 is not the one of SI genes in Phalaris, but represents a subclass of thioredoxin h. Thus a map-based cloning strategy was then adopted to clone the SI genes from Phalaris. Fine linkage maps of the S and Z regions were constructed. RFLP probes from wheat, barley, oat and rye were screened and the S locus was delimited to 0.26 cM and the Z locus to 1.0 cM from one side using specially designed segregating populations. The S locus was located to the sub-centromere region of triticeae chromosome group 1 and the Z locus to the middle of the long arm of group 2. Finally, barley and rice bacterial artificial chromosome (BAC) clones corresponding to the S and Z region were identified to analyse the chromosome structures and to seek candidate SI genes. The abundant repetitive sequences in the identified barley BAC clones limit their usefulness. Identification of Rice BAC clones orthologous to the S and Z regions open the gate to use rice genome information to clone SI genes from the grasses. A positive rice clone (139.9 kb) orthologous to the S region contained 19 predicted genes. Several of these genes might be involved in pollen tube germination and pollen-stigma interaction, which are the major parts of SI reaction. A positive clone (118.9 kb) orthologous to the Z region gave 16 predicted genes. The predicted genes on the outmost ends of these clones could be used to construct contigs to cover the S and Z regions and delimit the S and Z loci in the grasses.
