Plants have large amounts of the late embryogenesis abundant protein (LEA) family proteins, which is involved in osmotic regulation. The Korla Pear (Pyrus sinkiangensis Yu) an uncommon pear species that thrives Xinjiang and can survive below-freezing conditions. We found PsLEA4 gene was more expressed after cold treatment by looking at transcriptome data Pear. In order to evaluate biological function under low-temperature stress its potential for use agricultural breeding, we cloned from Pear, made a plant overexpression vector, transformed it into tomato via Agrobacterium transformation. When exposed low temperatures, regulate proline metabolism antioxidant enzyme activity tomatoes compared wild tomatoes. Because this, transgenic are resilient temperatures produce than their counterparts. Thus, expressing has multiple advantages: (1) Improving frost resistance reducing damage. (2) Increasing crop yield. Therefore, this study provides theoretical basis role plants’ resilience as well application breeding.

Genome-Wide Analysis of AGC Genes Related to Salt Stress in Soybeans (Glycine max)

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(6), P. 2588 - 2588

Published: March 13, 2025

The AGC protein kinase family plays a crucial role in regulating plant growth, immunity, and cell death, as well responses to abiotic stresses such salt-induced stress, which impact development productivity. While the functions of kinases have been thoroughly studied model plants Arabidopsis thaliana, their roles soybeans (Glycine max) remain poorly understood. In this study, we identified 69 genes soybeans, are unevenly distributed across 19 chromosomes classified into five subfamilies: PDK1, AGCVI, AGCVII, AGCVIII, (other). Each subfamily shares similar exon–intron structures specific motifs. Gene duplication selection pressure analyses revealed that GmAGC gene is primarily expanded through segmental or whole-genome duplication, with all undergoing purifying during evolution. Promoter analysis numerous cis-regulatory elements associated light, hormonal, stress responses, including salt stress. expression demonstrated tissue-specific patterns, highest levels found roots (19.7%). Among 54 analyzed using RT-qPCR, significant changes were observed leaves treated sodium chloride, most showing increased expression. These results illustrate critical soybean salinity Our findings suggest targeting may enhance resistance toxicity, offering valuable insights for future crop improvement strategies.

Decoding plant thermosensors: mechanism of temperature perception and stress adaption

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: March 25, 2025

Global climate change, characterized by increased frequency and intensity of extreme temperature events, poses significant challenges to plant survival crop productivity. While considerable research has elucidated responses stress, the molecular mechanisms, particularly those involved in sensing, remain incompletely understood. Thermosensors plants play a crucial role translating signals into cellular responses, initiating downstream signaling cascades that govern adaptive processes. This review highlights recent advances identification classification thermosensors, exploring their physiological roles biochemical mechanisms which they sense changes. We also address thermosensor discovery discuss emerging strategies uncover novel thermosensory with implications for improving resilience stress face rapidly changing climate.

The Current Status and Prospects of the Application of Omics Technology in the Study of Ulmus

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(23), P. 12592 - 12592

Published: Nov. 23, 2024

Elm (Ulmus) species are important components of forest resources with significant ecological and economic value. As tall hardwood trees that drought-resistant, poor-soil-tolerant, highly adaptable, Ulmus an excellent choice for ecologically protected forests urban landscaping. Additionally, the bioactive substances identified in fruits, leaves, bark, roots have potential applications food medical fields as raw materials industrial cosmetic applications. However, survival natural environment has been threatened by recurrent outbreaks Dutch elm disease, which led to death large numbers trees. In addition, severe damage habitats some is driving their populations extinction. Omics technology become tool collection, protection, biological characteristic analysis due its recent advances. This article summarizes current research application status omics Ulmus. The remaining problems noted, future directions proposed. Our review aimed at providing a reference resource conservation scientific into this genus.
