WebbIn enzymology, a leghemoglobin reductase (EC 1.6.2.6) is an enzyme that catalyzes the chemical reaction. NAD(P)H + H + + 2 ferrileghemoglobin NAD(P)+ + 2 ferroleghemoglobin. In other words, a leghemoglobin (or phytoglobin in general) with a Fe 3+ is reduced to one with the ferrous ion, Fe 2+.. This enzyme belongs to the family of oxidoreductases, … Webb27 sep. 2024 · In contrast to normoxia, hypoxia-induced NO does not react with superoxide, but rather is scavenged by phytoglobin1 via metaphytoglobin reductase activity. The scavenged NO has a role in recycling nitrate, maintenance of the redox status, and operation of the phytoglobin–NO cycle to generate ATP (Vishwakarma et al., 2024).

WebbBackground and aims: Drought reduces plant productivity, especially in the susceptible species Brassica napus. Water stress, mimicked by applications of 10% polyethylene glycol (PEG), elevates nitric oxide (NO) in root cells after a few hours contributing to the degradation of the root apical meristems (RAMs), the function of which relies on auxin … WebbFlooded plants experience impaired gas diffusion underwater, leading to oxygen deprivation (hypoxia). The volatile plant hormone ethylene is rapidly trapped in submerged plant cells and is instrumental for enhanced hypoxia acclimation. However, the precise mechanisms underpinning ethylene-enhanced h …

There is very good reason for such a link. Hypoxia in plants is not only a consequence of flooding but also occurs in dense plant tissues and organs growing …
Phytoglobins are globular plant (algae and land plant) proteins classified into the globin superfamily, which contain a heme, i.e. protoporphyrin IX-Fe, prosthetic group. The earliest known phytoglobins are leghemoglobins, discovered in 1939 by Kubo after spectroscopic and chemical analysis of the red pigment of … Visa mer Phytogbs are coded by genes interrupted by 3 introns (although a 4 introns-containing phytogb gene has been detected in the moss Physcomitrella patens ).
