Article Synopsis
  • Soybean is a vital global oilseed crop due to its high unsaturated fatty acid content, which directly affects its economic value.
  • Genetic variation in soybean cultivars leads to significant differences in seed oil content, but the specific genes regulating this trait are not fully understood.
  • This study identified the GmFATA1B gene as a key regulator of seed oil content and composition, and manipulating this gene can potentially improve soybean oil characteristics.

Introduction: Cadmium (Cd) stress is a significant threat to soybean production, and enhancing Cd tolerance in soybean is the focus of this study. The WRKY transcription factor family is associated with abiotic stress response processes. In this study, we aimed to identify a Cd-responsive WRKY transcription factor from soybean and investigate its potential for enhancing Cd tolerance in soybean.

Soybean is a major crop that produces valuable seed oil and protein for global consumption. Seed oil and protein are regulated by complex quantitative trait loci (QTLs) and have undergone intensive selections during the domestication of soybean. It is essential to identify the major genetic components and understand their mechanism behind seed oil and protein in soybean.

Cadmium (Cd) is a widely distributed heavy metal that is toxic to plants and humans. Although silicon (Si) has been reported to reduce Cd accumulation and toxicity in plants, evidence on the functions of Si and its mechanisms in the possible alleviation of soybean are limited. Therefore, a controlled experiment was conducted to investigate the impacts and mechanisms of Si on Cd retention in soybean.

Acyl activating enzyme 3 (AAE3) was identified as being involved in the acetylation pathway of oxalate degradation, which regulates the responses to biotic and abiotic stresses in various higher plants. Here, we investigated the role of () in Cadmium (Cd) and Aluminum (Al) tolerances. The recombinant GsAAE3 protein showed high activity toward oxalate, with a of 105.

Cadmium (Cd) is a widespread pollutant that is toxic to living organisms. Previous studies have identified certain WRKY transcription factors, which confer Cd tolerance in different plant species. In the present study, we have identified 29 Cd-responsive genes in Soybean [ (L.

Article Synopsis
  • - The study focuses on the IREG gene family in soybeans, which is crucial for regulating iron levels and managing metal stress, particularly aluminum.
  • - Researchers identified six IREG genes and highlighted one, GmIREG3, which increased aluminum resistance in transgenic plants, while not affecting tolerance to cobalt or nickel.
  • - The findings suggest GmIREG3 is a protein located in the tonoplast (the tonoplast is a membrane surrounding the vacuole), paving the way for future research on the roles of these genes in handling metal stress in plants.

The 2-acetyl-1-pyrroline (2AP) is a key aroma compound in fragrant rice. The present study assessed the γ-aminobutyric acid (GABA) and nitrogen (N) application induced regulations in the biochemical basis of rice aroma formation. Four N levels, that is, 0, 0.

Map-based cloning identified GmHAD1, a gene which encodes a HAD-like acid phosphatase, associated with soybean tolerance to low phosphorus stress. Phosphorus (P) deficiency in soils is a major limiting factor for crop growth worldwide. Plants may adapt to low phosphorus (LP) conditions via changes to root morphology, including the number, length, orientation, and branching of the principal root classes.
