Plant Lipoxygenases and Their Role in Plant Physiology
网页2020年3月13日 · These results established a role for the 9‐LOX pathway in modulating oxidative stress, lipid peroxidation, and plant defense. A rapid up-regulation of CaLOX1, a 9-LOX gene from pepper leaves, was detected during …

网页脂氧合酶(lipoxygenase,LOX,EC1.13.11.12),又名亚油酸: 氧氧化还原酶,俗称脂肪氧化酶、脂肪加氧酶、 脂肪氧合酶或类胡萝卜素氧化酶,广泛存在于哺乳动物、 植物和微生物中[1~3]。从生化的角度看,它是一种含非血红素铁或锰的加氧酶, 专一催化包括亚油酸、 亚麻酸 ...
The 9-lipoxygenase Osr9-LOX1 interacts with the 13-lipoxygenase ...
网页Oxylipins produced by the 13-lipoxygenase (LOX) have been reported to play an important role in plant defense responses to herbivores. Yet, the role of oxylipins produced by the 9-LOX pathway in this process remains largely unknown. Here we cloned a gene encoding a chloroplast-localized 9-LOX, Osr9-LOX1, from rice.
Role of 9-Lipoxygenase and α-Dioxygenase Oxylipin Pathways as ...
网页2012年7月1日 · Plant 9-lipoxygenases (9-LOX) and α-dioxygenases (α-DOX) initiate the synthesis of oxylipins after bacterial infection. Here, the role of these enzymes in plants’ defense was investigated using individual Arabidopsis thaliana lox1 and dox1 mutants and a double lox1 dox1 mutant.
9-Lipoxygenase-Derived Oxylipins Activate Brassinosteroid …
网页2015年9月28日 · Using lox1lox5 mutants that lack 9-LOX activity and the 9-LOX signaling mutant noxy2-2, we found that 9-LOX-derived oxylipins require brassinosteroid synthesis as well as active BR signaling to induce cell wall-based defenses and limit pathogen infection.
Transcript Abundance Patterns of 9- and 13-Lipoxygenase ... - PubMed
网页2019年9月5日 · Lipoxygenases (LOXs; EC 1.13.11.12) catalyze the oxygenation of fatty acids to produce oxylipins including the jasmonate family of plant hormones. The involvement of jasmonates in plant growth and development and during abiotic stress has been documented, however, the response and regulation of each ….
Genome-wide identification and expression pattern analysis of ...
网页2021年5月11日 · Banana LOXs showed a preference for using and ending with G/C and their encoded proteins can be classified into 9-LOX, Type I 13-LOX and Type II 13-LOX subfamilies. The expansion of the...
Lipoxygenases and Their Function in Plant Innate Mechanism
网页2019年9月20日 · Plant lipoxygenases are classified into two categories, based on positional specificity for linoleic acid oxygenation, i.e., 9-LOX and 13-LOX. 9-LOX lead to the oxygenation of linoleic acid at carbon atom 9 and 13-LOX at carbon atom 13 of the hydrocarbon backbone of the fatty acid and lead to the production of two groups of compounds, the (9S ...
Molecular, in silico and expression studies on lipoxygenases …
网页2023年11月28日 · Lipoxygenases (LOXs) namely 9-LOXs and 13-LOXs catalyse the oxygenation of polyunsaturated fatty acids to produce fatty acid hydroperoxides which are crucial in growth, development and stress responses in plants.
