WebFeb 27, 2008 · In wild type, bipyridyl-treatment largely enhanced the accumulation of pheide a (80 nmol g −1 fresh weight), but this increase was much smaller in JI2775 (35 nmol g −1 fresh weight). These data indicate that occurrence of pheide a is independent of PAO. Instead, pheide a formation could result from non-physiological conversion from chlide a ... WebAug 3, 2024 · In addition, more serious non-PCD occurred and more Pheide a accumulated in senescent leaves during dark incubation if the soil used for plant growth contained more water.

http://www.pedereide.com/ WebJun 19, 1998 · The conversion of Pheide a to a primary blue fluorescent catabolite (pFCC; Ref. 12) requires the joint action of PaO and a soluble stroma-located enzyme that reduces an intermediary red catabolite (RCC; Ref. 13) to pFCC (Fig. 1, Ref. 14 ). Both PaO and RCC reductase require reduced ferredoxin (Fd) as reductant.

WebJul 4, 2012 · Pheide a is then oxidatively ring opened by Pheide a oxygenase (PAO) (Pruzinska et al., 2003); this reaction is followed by reduction of fluorescent Chl catabolites to non-toxic molecules. In contrast, Chl b cannot be directly degraded; a formyl group of Chl b must be converted to a methyl group before degradation because PAO cleaves Pheide a … WebBackground. Our previous study has shown a prolonged retention and accumulation of Zn-pheophorbide a, a water-soluble derivative of chlorophyll a, in tumor tissue (Szczygiel et al.
