| Description |
Early leaf senescence occurred in spl32 mutant, confirmed by decreased pigment content and increased MDA content and SOD activity as physiological indicators, chloroplast degradation as cellular indicators, and both upregulation of senescence transcription factors (OsWRKY23 and OsWRKY72) and senescence-associated genes (Osl43 and Osl85) and downregulation of photosynthesis-related genes as molecular evidence. |
