High impact information on SEN1


Biological context of SEN1


Associations of SEN1 with chemical compounds

  • The encoded peptide shows noticeable similarity to the bacterial sulfide dehydrogenase and 81% identity to the peptide encoded by the radish din1 gene [7].
  • Expression of the sen1 gene was also strongly induced in leaves subjected to senescence by 0.1mM abscisic acid or 1 mM ethephon treatment [7].
  • In addition, the vtc1 mutant exhibits elevated levels of some senescence-associated gene (SAG) transcripts as well as heightened salicylic acid levels [11].
  • It is, however, leaf senescence-associated, and the other Cys proteinases are <52% identical [12].
  • Two MYB transcription factor genes, PAP1 and PAP2, were identified as senescence-associated genes that are induced by glucose [13].

Regulatory relationships of SEN1

  • Response to darkness of late-responsive dark-inducible genes is positively regulated by leaf age and negatively regulated by calmodulin-antagonist-sensitive signalling in Arabidopsis thaliana [14].
