![]() All these findings suggest that OsRP1L1 plays an important role in rice BB resistance, and may be useful as a genetic resource for engineering disease resistance in plants.Īzumi Y, Watanabe A (1991) Evidence for a senescence-associated gene induced by darkness. It was also noted that seven of the up-regulated genes have also reportedly been induced by overexpression of OsbZIP46, which has been identified recently as a player in ABA sensing. ![]() The most up-regulated transcripts-a DIN1-like gene and a terpene synthase ( TPS) gene-were up-regulated 7.9- and 7.6-fold, respectively. Transcriptome analysis showed that plants overexpressing OsRP1L1 had small changes in their transcriptome, with 26 genes showing statistically significant changes of more than two-fold. Overexpression of OsRP1L1 moderately elevated the resistance of plants to Xanthomonas oryzae pv. To explore its function in bacterial blight (BB) resistance, OsRP1L1 was cloned and overexpressed in a susceptible japonica rice cultivar. Expression patterns suggested that OsRP1L1 was involved in responses to several plant growth regulators (PGRs) and environmental stresses. ![]() ![]() Analysis of expression of a super green fluorescent protein ( sGFP) fusion gene revealed that the OsRP1L1 protein localizes to the nucleolus. Due to its similarity to Rp1 in maize ( Zea mays), a novel NB-LRR gene was isolated from rice and designated as OsRP1L1 ( Oryza sativa Rp1-like 1). Nucleotide-binding site leucine-rich repeat (NB-LRR) genes play important roles in plant disease resistance. ![]()
