- ... Plant defence against pathogens is controlled by disease resistance (R) gene products that directly or indirectly detect specific pathogen effectors. Plant-pathogen interactions have been proposed to follow a co-evolutionary arms-race model where R genes are recent and evolve rapidly in response to structural changes in matching pathogen effectors. However, the longevity and extensive polymorphism ...

- ... Gibberellic acid (GA) promotes germination, stem/hypocotyl elongation, and leaf expansion during seedling development. Using activation-tagging mutagenesis, we identified a mutation, sob2-D (for suppressor of phytochromeB-4 [phyB-4]#2 dominant), which suppresses the long-hypocotyl phenotype of a phyB missense allele, phyB-4. This mutant phenotype is caused by the overexpression of an APETALA2 tran ...
