Salicylic acid receptor NPR1 is involved in guard cell chitosan signaling
Bioscience, Biotechnology, and Biochemistry, 2020 Abstract Chitosan (CHT) induces stomatal closure and thus plays a crucial role in plants to adapt to the adverse environments. Our previous results of a SA-deficient mutant nahG suggest that endogenous salicylic acid (SA) is involved in the CHT signaling in guard cells.

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2350-2371, April 2026.ABSTRACT Colletotrichum spp., hemibiotrophic fungal pathogens, threaten global strawberry production. Jasmonate (JA) regulates plant‐Colletotrichum interactions, but its mechanisms remain unclear. Here we demonstrate that both exogenous methyl jasmonate (MeJA) treatment and elevated endogenous MeJA levels increase strawberry susceptibility to ...

Molecular Oncology, Volume 20, Issue 3, Page 753-778, March 2026.A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Exploring plant tolerance to biotic and abiotic stresses [PDF]
, 2007 Plants are exposed to many stress factors, such as drought, high salinity or pathogens, which reduce the yield of the cultivated plants or affect the quality of the harvested products. Arabidopsis thaliana was used as a model plant to study the responses

A universal primer for isolation of fragments of a gene encoding phytoene desaturase for use in virus-induced gene silencing (VIGS) studies [PDF]
, 2010 We have been using Virus-Induced Gene Silencing (VIGS) to test the function of genes that are candidates for involvement in floral senescence. Although VIGS is a powerful tool for assaying the effects of gene silencing in plants, relatively few taxa have

Feedback regulation of TORC1 by its downstream effectors Npr1 and Par32
Molecular Biology of the Cell, 2018 TORC1 (target of rapamycin complex) integrates complex nutrient signals to generate and fine-tune a growth and metabolic response. Npr1 (nitrogen permease reactivator) is a downstream effector kinase of TORC1 that regulates the stability, activity, and trafficking of various nutrient permeases including the ammonium permeases Mep1, Mep2, and Mep3 and ...
