Article Abstract

(bay bean), distributing in coastal areas or islands in tropical and subtropical regions, is an extremophile halophyte with good adaptability to seawater and drought. Late embryogenesis abundant (LEA) proteins typically accumulate in response to various abiotic stresses, including dehydration, salinity, high temperature, and cold, or during the late stage of seed development. Abscisic acid-, stress-, and ripening-induced (ASR) genes are stress and developmentally regulated plant-specific genes. In this study, we reported the first comprehensive survey of the LEA and ASR gene superfamily in . A total of 84 s and three s were identified in and classified into nine groups. All CrLEAs and CrASRs harbored the conserved motif for their family proteins. Our results revealed that the genes were widely distributed in different chromosomes, and all of the / genes showed wide expression features in different tissues in plants. Additionally, we introduced 10 genes from different groups into yeast to assess the functions of the s/s. These results contribute to our understanding of genes from halophytes and provide robust candidate genes for functional investigations in plant species adapted to extreme environments.

Cis-regulatory elements (CREs) precisely control spatiotemporal gene expression in cells. Using a spatially resolved single-cell atlas of gene expression with chromatin accessibility across ten soybean tissues, we identified 103 distinct cell types and 303,199 accessible chromatin regions (ACRs). Nearly 40% of the ACRs showed cell-type-specific patterns and were enriched for transcription factor (TF) motifs defining diverse cell identities.

Research Question: Is it possible to predict blastocyst quality, embryo chromosomal ploidy, and clinical pregnancy outcome after single embryo transfer from embryo developmental morphokinetic parameters?

Design: The morphokinetic parameters of 1011 blastocysts from 227 patients undergoing preimplantation genetic testing were examined. Correlations between the morphokinetic parameters and the quality of blastocysts, chromosomal ploidy, and clinical pregnancy outcomes following the transfer of single blastocysts were retrospectively analyzed.

Results: The morphokinetic parameters of embryos in the high-quality blastocyst group were significantly shorter than those in the low-quality blastocyst group (p < 0.

Late Embryogenesis Abundant (LEA) proteins are extensively distributed among higher plants and are crucial for regulating growth, development, and abiotic stress resistance. However, comprehensive data regarding the LEA gene family in Ipomoea species remains limited. In this study, we conducted a genome-wide comparative analysis across seven Ipomoea species, including sweet potato (I.

Low temperature is the main strategy to preserve fruit quality post-harvest, in the supply chain. Low temperatures reduce the respiration, ethylene emission, and enzymatic activities associated with senescence. Unfortunately, peaches are sensitive to low temperatures if exposed for long periods, resulting in physiological disorders that can compromise commercial quality.
