Chromosomal deletions drove parallel domestication of plant architecture in Asian and African rice

Project description:Improving the yield by modifying plant architecture is key to progressive crop domestication. Here, we show that a 110-kb deletion on the short arm of chromosome 7 promotes the critical transition from semi-prostrate growth and low yield in wild rice (Oryza rufipogon), to erect growth and high yield in Asian cultivated rice (O. sativa). The microdeletion harbors a tandem repeat of seven putative Cys2-His2 zinc-finger genes. Three of these genes regulate the plant architecture in O. rufipogon and are closely linked to the previously identified PROSTRATE GROWTH 1 (PROG1) gene. Therefore, we refer to this locus as RICE PLANT ARCHITECTURE DOMESTICATION (RPAD). Furthermore, a similar but independent 113-kb deletion was detected at the RPAD locus in African cultivated rice. These results indicate that the deletions, coupled with the loss of a tandem repeat of zinc-finger genes, drove the parallel domestication of plant architecture in Asian and African rice.

The transcription factor OsWRKY36 regulates lamina joint development and the leaf angle in rice by modulating brassinosteroid signalling

Project description:We identified a key regulator of the rice leaf angle and plant architecture, OsWRKY36, from a rice oswrky mutant library. OsWRKY36 is highly expressed in the leaf lamina joint and promotes cell growth and expansion in adaxial parenchyma cells, leading to a greater leaf angle.

Expression data from LRK1 060615 transgenic rice and control 9311

Project description:Plant height is a critical constituent of plant architecture. Rice (Oryza sativa) plants have the potential to undergo rapid internodal elongation, which determines plant height. A number of physiological studies have proved that gibberellin is involved in internode elongation. Leucine-rich repeat receptor-like kinases (LRR-RLKs) are the largest subfamily of transmembrane receptor-like kinases in plants. Plant LRR-RLKs play important functions in mediating a variety of cellular processes and regulating responses to environmental signals. LRK1, a PSK receptor homolog, is a member of the LRR-RLK family. In the present study, differences in ectopic expression of LRK1 were consistent with extent of rice internode elongation. Analyses of gene expression demonstrated that LRK1 restricts gibberellin responsiveness during the internode elongation process by down-regulation of the gibberellin biosynthetic gene, ent-KAURENE OXIDASE (OsKO2). Leaf tissues of 6-week-old LRK1 060615 transgenic rice and control 9311 rice (10 plants each) were selected.

Expression data in response to Xoo. bacterial infection in rice

Project description:In response to bacterial infection, early transcriptional re-programming occurs in the host plant. We used microarrays to analyse the global transcriptomic response to Xoo. infection in a resistant rice cultivar (IR24). This was analysed in parallel with microarrays examining Xoo infection in a susceptible rice cultivar (IRBB21) as well as in response to Xoc [GSE19239], viral [GSE11025], parasite [GSE10373] and fungal [GSE7256, GSE18361] infections in rice, in order to identify common and distinct responses to biotic stress.

Transcriptome profiling of Pythium graminicola-inoculated rice roots.

Project description:Contrary to the relative wealth of information regarding pathogen defense responses in aboveground plant parts, little is known about the mechanistic basis and regulation of plant immunity in root tissues. Aiming to further our fundamental understanding of root immune responses, we have investigated the interaction between rice and one of its major root pathogens, the oomycete Pythium graminicola. The specificic objectives of this study were twofold: i) to disentangle the molecular and genetic basis of the rice-Pythium interaction by comparing the transcriptome of rice roots at different times after inoculation with a highly virulent Pythium strains, and ii) to offer fundamental insights into the genetic architecture and regulation of rice disease resistance pathways operative in root tissue and to identify the molecular players controlling the possible nodes of convergence between these resistance conduits Comparison between P. graminicola- and mock-infected rice roots. Two treatments (infected and non-infected) x three timepoints (1, 2 and 4 days post inoculation) x three biological replicates
