The thylakoid membrane (TM) is a specialized structure present in most oxygen-evolving photosynthetic cyanobacteria and chloroplasts. VESICLE-INDUCING PROTEINS IN PLASTIDS 1 (VIPP1) is a key protein involved in TM biogenesis, shaping, and maintenance. VIPP1 originated from PspA and over time has specialized to the TM, which likely coevolved with the emergence of the C-terminal tail (Vc) present in VIPP1 but not in PspA.

Introduction: Resveratrol synthase (RS) is a key enzyme involved in the synthesis of stilbene and resveratrol. Resveratrol has many biological pharmacological activities that are beneficial to human health including anti-cancer, cardiovascular protection, estrogen regulation, antibacterial, antiviral, and reduction of tissue and organ damage. In plants, RS catalyzes the production of resveratrol, which helps to protect against fungal and bacterial diseases.

The presence of -, , gene family has been reported in many important plants, playing roles in various aspects of plant biology but little has been uncovered in soybeans. Soybean is one of the major plants providing nutrition for humans and livestock globally. In this study, we overexpressed a novel gene () in and conducted bioinformatic analyses, evaluated the T2 transgenic line in an open field, and applied major stressors along with the growth promoter GA to investigate the potential functions of the gene.

Protein elicitors can induce plant systemic resistance to pathogens. The recognition of a potential elicitor activates intracellular signaling events, leading to plant resistance against pathogens. In this study, a novel protein elicitor was isolated from the culture filtrate of and named PeVn1, which can induce cell death in several plant species.

Article Synopsis
  • Brassicanate A sulfoxide, a compound derived from broccoli, inhibits weed growth, but its exact mechanism of action is still being investigated.
  • The study examines how brassicanate A sulfoxide interacts with the photosystem II D1 protein, revealing that it forms hydrogen bonds with specific amino acids in the protein.
  • The research confirms through various experiments that brassicanate A sulfoxide has a strong binding affinity to the photosystem II D1 protein, which may help in creating natural herbicides targeting photosynthesis.

Allelopathic interactions between plants serve as powerful tools for weed control. Despite the increasing understanding of the allelopathic mechanisms between different plant species, the inhibitory effects of on weed growth remain poorly understood. In this study, we conducted experiments to demonstrate that extract can suppress the germination of L.

  • * The study identified 35 VOCs produced by S-16, focusing on four key compounds, particularly 2-methyl benzothiazole (2-MBTH), which is crucial for its antifungal properties.
  • * Deletion of the thiazole-biosynthesis gene in the S-16 strain led to a decrease in 2-MBTH production and a reduction in its ability to inhibit fungal growth, resulting in more severe damage to sunflower leaves compared to the wild-type strain.

Introduction: 2P24 was isolated from soil of natural decay associated with wheat take-all and it can effectively control soil-borne diseases caused by a variety of plant pathogens. 2,4-diacetylphloroglucinol (2,4-DAPG), is produced by 2P24 and plays an important role in the prevention and control of plant diseases. To understand the resistant mechanism, in this study, we conducted experiments to explore the regulation role of in the synthesis of the antibiotic 2,4-DAPG and regulation of QS system.

Article Synopsis
  • Botryosphaeria dothidea, responsible for apple white rot, has available genome data, but a gene manipulation method is needed for studying its pathogenic mechanisms.
  • A gene disruption (GD) method using polyethylene glycol-mediated protoplast transformation showed high efficiency, achieving a disruption rate of 1.3 per 10 protoplasts with fewer random insertions.
  • Successful gene disruptions resulted in altered traits, such as reduced melanin production and slower growth rate, indicating the method's potential for investigating gene functions and pathogenicity in B. dothidea and similar fungi.

Article Synopsis
  • Rhinoncus sibiricus, a pest of buckwheat, has been damaging buckwheat crops in China for many years, but its distribution and impact were not well understood.
  • Field surveys over 6 years indicated that the pest is more prevalent and causes greater damage in northern China compared to the south.
  • The study revealed that R. sibiricus prefers Tartary buckwheat (F. tataricum) over Common buckwheat (F. esculentum), suggesting its potential threat to southern Chinese buckwheat cultivation, which could inform pest control strategies.
