Unveiling the role of microRNAs in nonhost resistance to Sclerotinia sclerotiorum: Rice-specific microRNAs attack the pathogen via cross-kingdom RNAi.

The development of rapeseed with high resistance against the pathogen Sclerotinia sclerotiorum is impeded by the lack of effective resistance resources within host species. Unraveling the molecular basis of nonhost resistance (NHR) holds substantial value for resistance improvement in crops. In the present study, small RNA sequencing and transcriptome sequencing were carried out between rice (a nonhost species of S.

Effect of cerium-zirconium oxide-loaded red mud on the selective catalytic reduction of NO in downhole diesel vehicle exhaust.

Red mud (RM), an iron oxide-rich solid waste, shows potential as a catalyst for selective catalytic reduction in denitrification processes. This study investigates the catalytic performance and mechanism of metal-modified RM in reducing NO from diesel vehicle exhaust. Acid-washed RM catalysts were impregnated with varying ratios of cerium (Ce) and zirconium (Zr).

Electrospinning based biomaterials for biomimetic fabrication, bioactive protein delivery and wound regenerative repair.

Electrospinning is a remarkably straightforward and adaptable technique that can be employed to process an array of synthetic and natural materials, resulting in the production of nanoscale fibers. It has emerged as a novel technique for biomedical applications and has gained increasing popularity in the research community in recent times. In the context of tissue repair and tissue engineering, there is a growing tendency toward the integration of biomimetic scaffolds and bioactive macromolecules, particularly proteins and growth factors.

Brassinosteroid Enhances Cucumber Stress Tolerance to NaHCO by Modulating Nitrogen Metabolism, Ionic Balance and Phytohormonal Response.

Under NaHCO stress, exogenous 24-epibrassinolide (EBR) markedly alleviated Na accumulation in cucumber plants, thereby decreasing the Na/K, Na/Mg, and Na/Ca ratios. This mitigation was accompanied by elevated concentrations of K, Ca, and Mg, as well as enhanced expression of the and genes. In addition, the activities of plasma membrane H-ATPase, vesicular membrane H-ATPase, and vesicular membrane H-PPase were significantly increased, contributing to the maintenance of ionic balance in cucumber plants.

Exogenous 2,4-Epibrassinolide Alleviates Alkaline Stress in Cucumber by Modulating Photosynthetic Performance.

Brassinosteroids (BRs) are recognized for their ability to enhance plant salt tolerance. While considerable research has focused on their effects under neutral salt conditions, the mechanisms through which BRs regulate photosynthesis under alkaline salt stress are less well understood. This study investigates these mechanisms, examining plant growth, photosynthetic electron transport, gas exchange parameters, Calvin cycle dynamics, and the expression of key antioxidant and Calvin cycle genes under alkaline stress conditions induced by NaHCO.
