Parasitic Plant-Host Interactions: Molecular Mechanisms and Agricultural Resistance Strategies. [PDF]

Adv Sci (Weinh)
Parasitic plants devastate global agriculture through sophisticated molecular interactions with host crops. This review synthesizes current understanding of parasitic plant‐host interactions, from strigolactone‐mediated germination and haustorium formation to host defense mechanisms.

6-Hydroxynicotinic Acid From Cucumis melo Inhibits Prehaustorium Formation in Phelipanche aegyptiaca via Disruption of Auxin Signalling Pathway. [PDF]

Mol Plant Pathol
6‐hydroxynicotinic acid inhibits prehaustorium development in Phelipanche aegyptiaca by inhibiting GH3‐mediated auxin conjugation, downregulating key auxin‐responsive genes, and impairing the auxin transporter AUX1. ABSTRACT Phelipanche aegyptiaca, a root holoparasitic weed, severely threatens agricultural productivity due to its detrimental effects ...

A Riboflavin-Derived Flavinium Salt Mediates Chemoselective Methylation Reactions. [PDF]

Chemistry
A two‐component methylation protocol was developed, where the active flavin mediator can be recycled in a single step. Crystallographic data and NMR spectroscopy support the mechanistic proposal, while chemoselective methylation was observed for a broad range of biologically relevant substrates. ABSTRACT Selective methylation is among the most relevant

Differences in photosystem II activity and carbon allocation during photomixotrophic growth in distinct wild-type strains of Synechocystis sp. PCC 6803. [PDF]

Plant J
SUMMARY The regulation of photosynthetic electron transport during photomixotrophic growth in cyanobacteria remains incompletely understood. In this study, we characterized four wild‐type strains (WT 1–4) of Synechocystis sp. PCC 6803 and observed distinct strain‐specific differences in photosystem II (PSII) function under photomixotrophic conditions ...

2,6-DMBQ suppresses cell proliferation and migration via inhibiting mTOR/AKT and p38 MAPK signaling pathways in NSCLC cells

Journal of Pharmacological Sciences, 2021
2,6-Dimethoxy-1,4-benzoquinone (2,6-DMBQ) is the major bioactive compound found in fermented wheat germ extract. Although fermented wheat germ extract has been reported to show anti-proliferative and anti-metabolic effects in various cancers, the ...

Plant cell surface receptors. [PDF]

Plant J
SUMMARY Plants face constant environmental changes and must integrate external and internal cues to coordinate growth, development, reproduction, and stress responses. A major strategy is perception at the cell surface via a large, diverse network of receptors.

Investigation of the effect of salt stress on photosynthetic electron transport pathways in the Synechocystis PCC 6803 cyanobacterium. [PDF]

Physiol Plant
Abstract Cyanobacteria are important model organisms for studying the process of photosynthesis and the effects of environmental stress factors. This study aimed to identify the inhibitory sites of NaCl in the whole photosynthetic electron transport in Synechocystis sp. PCC 6803 WT cells by using multiple biophysical tools. Exposure of cells to various

Molecular level insights into the direct health impacts of some organic aerosol components [PDF]

, 2021
Organic aerosols (OAs) comprise 20-90 w% of atmospheric aerosols. While they have some positive impacts (e.g. acting as precipitation nuclei), they can pose some negative impacts on human health.

Allylsulfones through Palladium-Catalyzed Allylic C−H Sulfonylation of Terminal Alkenes [PDF]

, 2023
Two previously unknown protocols for Pd-catalyzed allylic C-H sulfonylation of terminal alkenes have been developed. While the former consists of a direct Pd(II)-catalyzed oxidative C-H allylic sulfonylation in the presence of sulfinate anions, the ...
