Special Issue Information

Dear Colleagues,

Plants are faced with numerous environmental challenges, such as drought, salinity, temperature fluctuations, and pathogen attacks. These stresses are the primary cause of crop loss worldwide, reducing average yields for most of the major crop plants by more than 50%. To survive and thrive in these adverse conditions, plants have evolved complex stress response mechanisms that enable them to maintain homeostasis and protect their essential metabolic processes. The molecular and genetic basis of these mechanisms is an area of active research and has significant implications for the development of more resilient crops and the improvement of food security in a changing climate.

This Special Issue aims to shed light on the molecular and genetic mechanisms that enable plants to adapt and survive in adverse environmental conditions. The articles included in the Special Issue will cover a range of topics including, but not limited to, the identification of novel genes involved in the stress response, the characterization of their functions, and the development of genetic strategies for improving stress tolerance in crops. The studies presented in the Special Issue will highlight the complex interplay between the genetic and environmental factors in determining a plant's stress tolerance and provide a deeper understanding of the biological processes involved.

We welcome all manuscript types (original studies, reviews, communications, opinions, perspectives and discussions) that focus on novel topics including, but not limited to, the listed keywords.

Dephosphorylation is one of the important mechanisms regulating signal transduction in plant growth and development and in response to abiotic stresses. Type-one protein phosphatases (TOPPs) catalyze a significant number of important dephosphorylation events in cells, and play essential roles in plant developmental regulations and multiple stress responses. Nevertheless, the knowledge regarding the peanut’s TOPP gene family remains extremely restricted. Thirteen TOPP genes (AhTOPP1-13) were discovered in the peanut genome database through the utilization of HMMER and BLASTP methods in this research. The thirteen AhTOPP genes were classed into three clades together with their Arabidopsis homologs based on phylogenetic tree, and mapped on nine of twenty chromosomes. The examination of gene compositions and protein patterns indicated resemblance in the structure of exons and introns, as well as the arrangement of motifs within the identical clade, which further reinforces the findings of phylogenetic analysis. All AhTOPP proteins possessed STPPase_N, Metallophos domains, and the core catalytic sites. Promoter analysis showed that the AhTOPP genes may be widely involved in peanut development, hormones, and stress response. The RNA-seq data revealed the presence of AhTOPP genes in twenty-two tissues, suggesting potential variations in the functionality of AhTOPP genes. Furthermore, drought and salt stresses induced the expression of multiple AhTOPP genes, including AhTOPP1, AhTOPP4, AhTOPP7, AhTOPP9, and AhTOPP13. It is worth mentioning that the AhTOPP genes’ expression could potentially be controlled by various transcription factors with different functions, including ERF, WRKY, MYB, and Dof. We will conduct specific functional studies on the peanut TOPP genes through transgenics in future research. Full article
