Induction of phenylalanine ammonia lyase and pisatin by photosensitive psoralen compounds.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The psoralen compounds, xanthotoxin and 4,5', 8-trimethylpsoralen, when activated, increased phenylalanine ammonia lyase (PAL) activity and the synthesis of pisatin in excised pea pods. Pods presoaked 1 hr with 4,5',8-trimethylpsoralen and then irradiated 4 minutes with 366 nanometer ultraviolet

Induction of 6a-hydroxymaackiain 3-O-methyltransferase and phenylalanine ammonia-lyase mRNA translational activities during the biosynthesis of pisatin.

Ingia / Ingia

The isoflavonoid phytoalexin pisatin is synthesized by pea (Pisum sativum L.) in response to microbial infection and certain other forms of stress. The terminal step in the biosynthesis of pisatin is catalyzation by the (+)-6a-hydroxymaackiain 3-O-methyltransferase (HMKMT). This enzyme, identified

L-Phenylalanine ammonia-lyase and pisatin induction by 5-bromodeoxyuridine in Pisum sativum.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The substitution of the base analogue 5-bromodeoxyuridine (BrdU) for thymidine in the DNA of pea pods (Pisum sativum) induces or enhances the level of phenylalanine ammonia-lyase (PAL) and also induces the phytoalexin, pisatin, a product of the same metabolic pathway. Cordycepin, a polyadenylate

Functional analysis of the promoters of phenylalanine ammonia-lyase genes in pea.

Ingia / Ingia

Pycnospore germination fluid of Mycosphaerella pinodes, a fungus pathogenic on pea, contains both an elicitor and a suppressor of the accumulation of pisatin, a major phytoalexin of pea. Transcription of the genes encoding key enzymes in the biosynthesis of pisatin, namely PAL (a gene encoding

Purification and Characterization of S-Adenosyl-l-methionine:6a-Hydroxymaackiain 3-O-Methyltransferase from Pisum sativum.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

The isoflavonoid phytoalexin pisatin is synthesized by Pisum sativum in response to microbial infection and certain other forms of stress. An enzyme which synthesizes pisatin by methylating the 3-hydroxyl of (+)6a-hydroxymaackiain (HMK) was extracted from CuCl(2)-stressed pea seedlings. The enzyme

Soybean Sudden Death Syndrome Caused by Fusarium virguliforme is Impaired by Prolonged Flooding and Anaerobic Conditions.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

High soil moisture usually favors soybean sudden death syndrome (SDS), caused by Fusarium virguliforme (Fv), but the effects of the duration of the flooding period and accompanying anaerobic conditions on the soybean-Fv interaction are not clear. Greenhouse studies were conducted using susceptible
