Texto completoRestoration of fertility in Brassica napus nap and pol CMS is associated with nuclearly encoded genes Rfn and Rfp, respectively. These restorers are very closely linked to one another, and may be allelic. Further efforts to isolate Rfp have narrowed the genomic region to approximately 105 kb of a syntenic region in Arabidopsis thaliana. Cosmid clones isolated from a library of Brassica rapa genomic DNA introgressed with Rfp have been successfully sorted into contigs through the application of the amplified fragment length polymorphism technique. The region to which Rfp is mapped is syntenic to a region of Arabidopsis DNA that is a duplication of a second location at the 23 megabase region of chromosome 1 of that genome. This region contains pentatricopeptide (PPR) motif-encoding genes that are highly related to other restorers of fertility of other species. By inference, Rfp from Brassica napus may encode PPR motifs. The PPR genes related to these previously characterized restorers of fertility are often found alongside the restorer genes existing as mini-clusters of several PPR-encoding genes. This is likely caused by selective pressure acting on PPR-encoding genes that resulted in diversification and multiplication of these genes. In addition, the PPR genes of this duplicated region are not syntenically located, whereas the non-PPR-encoding genes maintain their syntenic locations. The same is true for orthologous comparisons between Arabidopsis and other plant species. PPR genes are therefore malleable and capable of alteration in response to changing environmental pressures, such as the evolution of sterility inducing genes.

Texto completoImproving rapeseed yields in a low-Nitrogen (N) agricultural context is a major issue for breeding. It requires a thorough knowledge of the genotypic variation of the processes related to Nitrogen Use Efficiency (NUE, seed yield per unit of N available). This PhD aims at better understanding the ecophysiological processes determining the NUE and its components under low-N availability by identifying and hierarchizing the main traits supporting observed genotypic variation. Six winter oilseed rape genotypes were investigated throughout the crop cycle under semi-controlled conditions and contrasting N-conditions. We proposed NUE_DM (plant dry matter per unit of N available), as a new proxy of NUE at harvest, valid as early as the beginning of stem elongation. This proxy allowed us to dynamically characterize NUE, highlighting NUpE (plant N-amount per unit of N available) as a main contributor of NUE under low-N conditions, which explained up to 80% of the NUE_DM variations before flowering, and more than 30% after. Moreover, NUpE genotypic variability resulted from fine root growth rather than specific N-uptake differences. We developed a whole-plant conceptual modeling framework of carbon and nitrogen absorption and partitioning for winter oilseed rape. This framework, validated up to flowering, highlighted specific carbon assimilation, carbon partitioning between leaves and stems, and fine root ratio as critical traits explaining contrasting genotypic behavior to N-conditions. Our results suggest NUpE and fine root ratio as promising traits for screening larger sets of varieties for NUE breeding purposes

The aim of this work was to study the parasitism of Meloidogyne incognita on native plants from Western Paraná, Brazil, as well as to assess the genetic variability among different populations belonging to the race 3 of this nematode by RAPD technique. Natural infection was studied in thirty six native plant species, which were identified on the basis of the perineal pattern from mature females and esterase phenotype. Native species that showed no infestation on the root system were inoculated with 1.000 eggs and/or J2 of M. incognita. After 60 days, the inoculated plants were evaluated regarding the number of galls and the number of eggs/or J2 per root. The genetic variability from different single female populations of M. incognita race 3 was studied by RAPD technique, having been tested 10 primers. The native plants that were susceptible to M. incognita parasitism were Rabo-de-Bugio (Lonchocarpus muehlbergianus Hassl.), Ipê Roxo (Tabebuia impetiginosa Mart. Ex DC. Standl), Sanga D água (Croton urucurana Boill), Ipê Amarelo (Tabebuia ahrysotricha Mart ex DC. Standl.), Genipapo (Genipa americana L.), Ariticum Comum (Rollinia mucosa (Jacq.) Baill.) and Aroeira Vermelha (Schinus terebinthifolius Raddi.). On the other hand, M. javanica was found parasiting Café de Bugre (Cordia ecalyculata Vell.), Guatambu Vermelho (Aspidosperma subincanun Mart.) and Tarumã Branco (Cytrarexllum myruanthum Cham.). The DNA polymorphism showed that there was genetic variability among populations from a same race (3) of M. incognita, allowing the separation of them into five genetic groups, through reactions with the primers (O)AK20, A10, AQ12, AS08 and (OP)F01
Objetivou-se com o presente trabalho estudar o parasitismo de Meloidogyne incognita em plantas nativas do oeste paranaense, bem como a variabilidade genética de populações de M. incognita raça 3 pela técnica RAPD. Trinta e seis espécies de plantas nativas foram analisadas com relação à infecção natural por Meloidogyne spp. A identificação de Meloidogyne foi feita com base na configuração perineal de fêmeas maduras e no fenótipo para a isoenzima esterase. Espécies nativas com ausência de galhas no sistema radicular foram inoculadas com 1.000 ovos e/ou J2 de uma população de campo de M. incognita. Após 60 dias da inoculação, as plantas foram avaliadas com relação ao número de galhas e número de ovos e/ou juvenis por raiz. A variabilidade genética de diferentes populações monoespecíficas de M. incognita raça 3 do noroeste paranaense foi estudada pela técnica RAPD com o teste de 10 primers. As plantas nativas hospedeiras de M. incognita foram Rabo-de-Bugio (Lonchocarpus muehlbergianus Hassl.), Ipê Roxo (Tabebuia impetiginosa Mart. Ex DC. Standl), Sanga D água (Croton urucurana Boill), Ipê Amarelo (Tabebuia ahrysotricha Mart ex DC. Standl.), Genipapo (Genipa americana L.), Ariticum Comum (Rollinia mucosa (Jacq.) Baill.) e Aroeira Vermelha (Schinus terebinthifolius Raddi.). Já M. javanica foi encontrado parasitando Café de Bugre (Cordia ecalyculata Vell.), Guatambu Vermelho (Aspidosperma subincanun Mart.) e Tarumã Branco (Cytrarexllum myruanthum Cham.). A análise do polimorfismo do DNA possibilitou a detecção de variabilidade genética para diferentes populações de uma mesma raça (3) de M. incognita, permitindo a separação das populações em 5 grupos genéticos, através de reações com os primers AK20, A10, AQ12, AS08 e F01

Texto completoxv, 159 leaves : ill. (some col.) ; 30 cm.
Boron efficiency in oilseed rape (Brassica napua L. and B. juncea L.) was investigated in a wide range of genotypes. Using a solution culture screening of 10 day old seedlings, root length best described shoot growth response, and was used to characterise a total of 65 genotypes. Varieties and breeders lines tolerant of B-deficient growing conditions were identified, and the screening process validated through field trials. B responses in plants sampled at the 'green bud' stage indicated that vegetative growth is important in B efficiency. Studies were conducted to investigate the mechanism of B efficiency in oilseed rape. Results suggest no association between B efficiency and the capacity to acidify the root rhizosphere, or an increased translocation of B from root to shoot. Boron retranslocation was also studied as a mechanism of B efficiency.
