Novel 2[small alpha]-methyl-, 2[small alpha]-(3-hydroxypropyl)- and 2[small alpha]-(3-hydroxypropoxy)-substituted 25-dehydro-1[small alpha]-hydroxyvitamin D-26,23-lactone derivatives were efficiently synthesized Reformatsky type allylation and palladium-catalyzed alkenylative cyclization processes, and their biological activities were evaluated. Introducing functional groups into the 2[small alpha]-position of the vitamin D-26,23-lactones resulted in remarkable enhancement of their antagonistic activity on vitamin D receptor (VDR).

Fungal diseases in agricultural crops cause economic losses, with chemical control being the conventional method to manage them. However, this approach negatively impacts both the environment and human health. This study focused on endophytic fungi isolated from the roots of Ceratozamia mirandae in the Mexican locality of Juan Sabines (Villa Corzo, Chiapas).

Sweet potato foot rot disease caused by Diaporthe destruens (formerly Plenodomus destruens) severely affects the yield and quality of sweet potatoes. To gain basic knowledge on regulating the pathogen using indigenous soil bacteria, the following organic materials were applied to potted soils collected from a sweet potato field contaminated with D. destruens: Kuroihitomi (compost made from shochu waste and chicken manure), Soil-fine (material made by adsorbing shochu waste on rice bran), and rice bran.

A comprehensive understanding of the interplay between agricultural practices and the rhizosphere microbiome particularly the role of root exudates is essential for harnessing microbial potential in sustainable agriculture. In this study, we investigated how disease-suppressive soil alters root exudate profiles in pepper plants and how these elevated exudates influence rhizosphere microbiome assembly and modulate the antagonistic activity of Bacillus methylotrophicus 400 (BM400) against Phytophthora capsici. GC-MS analysis identified distinct compositional profiles of root exudates in the disease-suppressive soil, with marked enrichment of seven compounds.

Wheat production is limited by the rapid expansion of salinized arable land worldwide. Identification of the molecular mechanisms that underlie the salt stress response is of great importance. Here, we uncovered the NAC-type transcription factor, TaVOZ1, as a positive regulator of wheat salt tolerance.
