Explanation
|
Q93VB5. AC111015. KC610831-KC610843 (O. sativa and wild rice species, partial cds). AY885947-AY885975 and DQ374857-DQ374884 (O. sativa and other wild rice species, partial cds). Relatively small reddish brown spots scattering over the whole surface of leaves. They appear from tillering stage to heading time. The phenotypes of spl3, spl5 and spl7 are similar, being difficult to distinguish each other. [137] OsHSF15 in Muthuramalingam et al. 2019. GRO:0007048; 04-stem elongation stage ; GRO:0007148; 05-booting stage ; GRO:0007049; 03-tillering stage ; GRO:0007044; 06-heading stage. GO:2000377: regulation of reactive oxygen species metabolic process. GO:1900425: negative regulation of defense response to bacterium. GO:1900150: regulation of defense response to fungus. GO:0140426: pathogen-associated molecular pattern receptor signaling pathway.
