Abstract Variations in the nutrients and water that plants require for metabolism, development, and the maintenance of cellular homeostasis are the main causes of abiotic stress in plants. It has, however, hardly ever been studied how these transporter proteins, such as aquaporin which is responsible for food and water intake in cell plasma membranes, interact with one another. This review aims to explore the interactions between nutrient transporters and aquaporins during water and nutrient uptake. It also investigates how symbiotic relationships influence the plant genome’s responses to regulatory processes such as photoperiodism, senescence, and nitrogen fixation. More >

Abstract Aluminum-activated malate transporters (ALMT) are widely involved in plant growth and metabolic processes, including adaptation to acid soils, guard cell regulation, anion homeostasis, and seed development. Although ALMT genes have been identified in Arabidopsis, wheat, barley, and Lotus japonicus, little is known about its presence in Gossypium hirsutum L. In this study, ALMT gene recognition in diploid and tetraploid cotton were done using bioinformatics analysis that examined correlation between homology and evolution. Differentially regulated ALMT genetic profile in G. hirsutum was examined, using RNA sequencing and qRT-PCR, during six fiber developmental time-points, namely 5 d, 7 d, 10 d, 15 d,… More >

Abstract As the preferred nitrogen (N) source, ammonium (NH₄⁺ ) contributes to plant growth and development and fruit quality. In plants, NH₄⁺ uptake is facilitated by a family of NH₄⁺ transporters (AMT). However, the molecular mechanisms and functional characteristics of the AMT genes in peach have not been mentioned yet. In this present study, excess NH₄⁺ stress severely hindered shoot growth and root elongation, accompanied with reduced mineral accumulation, decreased leaf chlorophyll concentration, and stunned photosynthetic performance. In addition, we identified 14 putative AMT genes in peach (PpeAMT). Expression analysis showed that PpeAMT genes were differently expressed in peach… More >
