Hainan's unique climate significantly contributes to soil acidification, causing phosphorus fixation into insoluble compounds, leading to phosphorus deficiency and reduced yield in sweet potatoes. The family, a group of trans-membrane phosphate transporters, is crucial for phosphate transport, distribution, and homeostasis regulation. Two genes, and , were first identified in sweet potato, and a phylogenetic analysis of 46 species showed high conservation of the gene family throughout plant evolution.

The HVA22 family of genes, induced by abscisic acid and stress, encodes a class of stress response proteins with a conserved TB2/DP1/HVA22 domain that are unique among eukaryotes. Previous studies have shown that play an important role in plant responses to abiotic stresses. In the present study, 34, 32, 16, and 17 were identified in , , , and , respectively.

Background: Plants suffer from various abiotic stresses during their lifetime, of which drought and salt stresses are two main factors limiting crop yield and quality. Previous studies have shown that abscisic acid (ABA) responsive element binding protein (AREB)/ ABRE binding factors (ABFs) in bZIP transcription factors are involved in plant stress response in an ABA-dependent manner. However, little is known about the properties and functions of AREB/ABFs, especially ABF3, in cotton.

Background: Salinity is a major abiotic stress seriously hindering crop yield. Development and utilization of tolerant varieties is the most economical way to address soil salinity. Upland cotton is a major fiber crop and pioneer plant on saline soil and thus its genetic architecture underlying salt tolerance should be extensively explored.

Article Synopsis
  • Cotton is a crucial natural fiber and a significant source of nutrition for humans and livestock, and this study focuses on the genetic architecture of its seed nutrients through a genome-wide association study (GWAS) involving 196 germplasm resources.
  • The research found high genetic diversity and phenotypic variation, revealing a negative correlation between seed protein and oil content, likely linked to oleic acid levels.
  • The study identified 47 significant SNP markers and 28 candidate quantitative trait loci (QTL) regions associated with key seed nutrients, enhancing the understanding of genetic factors influencing cottonseed nutrient composition and aiding the development of improved cotton cultivars.

Article Synopsis
  • Codon usage bias (CUB) is a key evolutionary characteristic that helps understand organism evolution and gene expression, and this study analyzed CUB in four cotton species: G. arboreum, G. raimondii, G. hirsutum, and G. barbadense.
  • The results indicated that these cotton species have a weak CUB, with a preference for pyrimidine-rich codons and that factors like translational selection and mutations significantly influence their codon usage patterns.
  • Additionally, the study identified 25 high-frequency and 31 low-frequency codons based on their terminal bases, concluding that weak codon usage bias exists, predominantly driven by translational selection across these cotton genomes.
