Basic information
GenBank ID	AB267825
Alias	InPSR26
Organism	Japanese morning glory (Ipomoea nil)
Taxonomic identifier	[NCBI]
Function category	Lipid/Carbohydrate metabolism:Macromolecule degradation
Effect for Senescence	delay
Gene Description	InPSR26 is dominantly expressed in petal limbs and its transcript level increases prior to visible senescence symptoms. Transgenic plants with reduced InPSR26 expression (PSR26r lines) showed accelerated petal wilting, with PCD symptoms including cell collapse, ion and anthocyanin leakage, and DNA degradation accelerated in petals compared to wild-type plants. Transcript levels of autophagy- and PCD-related genes (InATG4, InATG8, InVPE, and InBI-1) were reduced in the petals of PSR26r plants. InPSR26 acts to delay the progression of PCD during petal senescence, possibly through regulation of the autophagic process.
