SUMMARY: In higher plants, multiple nuclear-encoded sigma factors activate select subsets of plastid gene promoters in a partially redundant manner. We analysed the light induction profiles of transcripts from six Arabidopsis sigma factor AtSIG genes in mature leaves, focusing on the effects of wavelength and intensity. AtSIG1 transcripts increased to plateau with a threshold of 2 micromol m -2 sec -1 under all fluences examined micromol m -2 sec -1and AtSIG5 transcripts were induced with a distinct two-phase profile, with the lower-fluence induction similar to that of AtSIG1 and further enhancement with increasing fluences greater than 10 micromol m -2 sec Blue-light-receptor mutational analysis revealed that AtSIG5-specific two-phase induction is mediated through cryptochrome 1 and cryptochrome 2 at lower fluences and more significantly through cryptochrome 1 at higher fluences.

Oh my god! I could be here a whole day just looking and looking. Personally, i was hoping for more mature women, i like them best!
