Transcriptomics and metabolomics analyses provide insights into postharvest ripening and senescence of tomato fruit under low temperature

Horticultural Plant Journal, 2023
Tomato is one of the most important vegetable crops in the world and is a model plant used to study the ripening of climacteric fleshy fruit. During the ripening process of tomato fruit, flavor and aroma metabolites, color, texture and plant hormones ...

Hormonal Status of Transgenic Birch with a Pine Glutamine Synthetase Gene during Rooting In Vitro and Budburst Outdoors

Biomolecules, 2023
Improving nitrogen use efficiency (NUE) is one of the main ways of increasing plant productivity through genetic engineering. The modification of nitrogen (N) metabolism can affect the hormonal content, but in transgenic plants, this aspect has not been ...

The destruction of indoleacetic acid. III. Relationships between peroxidase action and indoleacetic acid oxidation [PDF]

Archives of Biochemistry and Biophysics, 1960
Abstract The indoleacetic acid (IAA)-oxidizing enzyme preparation from Omphalia flavida exhibits peroxidase activity on pyrogallol with an optimum at pH 3.5–3.7, like that for the IAA-oxidizing activity. It shows no polyphenolase activity. Peroxidase and IAA-oxidizing activities run parallel both during thermal inactivation and in course of ...

Metabolism of Indoleacetic Acid in Rust Diseases. II. Metabolites of Carboxyl-labeled Indoleacetic Acid in Tissues [PDF]

Plant Physiology, 1964
In a previous paper (6), we reported different rates of decarboxylation of indoleacetic acid (IAAC14OOH) by healthy and rust-affected wheat leaves in the dark. As a result of infection the rate of decarboxylation first increased, but several days later, as the rust began to sporulate, declined to become much lower than that of healthy leaves.

Indoleacetic Acid Studies in Man.

Experimental Biology and Medicine, 1948
SummaryThe addition of 25 to 200 mg of indoleacetic acid per day to a diet low in protein and nicotinic acid appears to have no significant effect upon the utilization of tryptophane and nicotinic acid by man as evidenced by urinary excretion studies.

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

Advanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...

Ingenious characterization and assessment of lentil germplasm collection to aphid Acyrthosiphon pisum stress unveils distinct responses

Frontiers in Plant Science, 2022
Lentil cultivation is often hampered by aphid population outspreads with detrimental impacts to crop development and production, challenging food safety and agriculture sustainability. The pea aphid (Acyrthosiphon pisum) is a significant threat to lentil
