ORANGE proteins mediate adaptation to high light and resistance to Pseudomonas syringae in tomato by regulating chlorophylls and carotenoids accumulation.

Chlorophylls and carotenoids are crucial for photosynthesis and plant survival, with ORANGE (OR) protein being pivotal in pigment accumulation. Despite tomato being rich in carotenoids, the roles of OR proteins in tomato have been overlooked. Herein, we characterized two OR genes in tomato, SlOR and SlOR-like, which are highly expressed in stems, leaves, and flowers, with their proteins being localized to chloroplasts.

Cooperative Pd/Chiral Secondary Amine Enabled Diastereo- and Enantioselective [3 + 2] Cycloannulation: Synthesis of Polysubstituted Cyclopentanes.

A cooperative palladium/chiral amine enabled diastereo- and enantioselective [3 + 2] cycloaddition of π-allyl 1,3-dipoles with α,β-unsaturated aldehydes has been developed. A series of highly functionalized cyclopentanes bearing three continuous tertiary stereocenters can be facilely and efficiently obtained in good to excellent yields (51-97%) with synthetically useful diastereo- and enantioselectivity (93-99% ee) under mild reaction conditions. Control experiments and HRMS analyses were conducted to elucidate the possible mechanism.

Trichothecroamides A‒F, antifungal amides from potato associated fungus Trichothecium crotocinigenum.

Potato is the most important non-cereal food crop in the world.

As a continuation of the search of natural fungicides from the secondary metabolites of potato associated fungus Trichothecium crotocinigenum, five previously undescribed amide derivatives trichothecroamides A‒E, one previously undescribed cyclopeptide trichothecroamide F, together with three known cyclopeptides, have been obtained.

Enhancing remediation efficiency of cadmium-contaminated soil: integrating forage-microorganism systems with agronomic strategies.

Soil contamination due to heavy metals, especially cadmium (Cd), poses a growing concern. This study seeks to develop an economical and non-polluting sustainable remediation program for Cd-contaminated soil to address this issue. This study pioneered the exploration of Cd accumulation patterns in three forage species: Lolium multiflorum Lamk (LMJS), Sorghum bicolor × sudanense (SSBJ), and Sorghum sudanense (Piper) Stapf (SUJS) to identify their optimal harvest periods in Cd-contaminated soils.

Discovery of highly oxygenated cytochalasans with antiproliferative activity from an endophytic fungus Boeremia exigua.
