Comment | The protein is encoded by a single copy gene in rice. It is the alpha subunit of the heterotrimeric G-protein complex. Immunoblot analysis using anti-RGA1 revealed that the RGA1 protein is most abundant in seedling leaves and least abundant in mature roots. It exists at particularly high levels in the immature embryo after pellicle extrusion. d1 mutants exhibited a highly reduced hypersensitive response to infection by an avirulent race of rice blast. Activation of PR gene expression in the leaves of the mutants infected with rice blast was delayed for 24 h relative to the wild type. H(2)O(2) production and PR gene expression induced by sphingolipid elicitors (SE) were strongly suppressed in d1 cell cultures. Expression of the constitutively active OsRac1, a small GTPase Rac of rice, in d1 mutants restored SE-dependent defense signaling and resistance to rice blast. The gene expression was induced by an avirulent race of rice blast and SE application on the leaf. A typical small grain dwarf type with short and stout stems, short, sinuate but broad leaves with dark green color, erect and compact panicles and small, round floral glumes. Internodes are thick and sometimes the second internode does not elongate. (Imported from Gene GR:0060184) |
