Special Issue Information

Dear Colleagues,

Human beings’ reliance on food is increasing with the increasing world population. Thus, we pay more attention to the yield and quality of crops. However, crops such as wheat, rice, maize, barley, potato, soybean, rape seed, and common bean have to cope with biotic and abiotic stresses under adverse conditions. It has been revealed that the yield of crops is decreased under stressful conditions to balance development, growth, and resistance to stresses. Hence, understanding and revealing the underlying mechanisms is of importance to meet the food needs and guarantee food safety at the physiological, biochemical, molecular, and genetic level. With the development of new tools such as CRISPR-cas9-based gene editing, single-cell sequencing, and omics, as well as genetics and molecular plant-biology-related research approaches, our knowledge about crops’ responses to stresses is accumulating.  

In order to present the recent advances on molecular responses to and management strategies for crop stress and to stimulate fruitful discussions, the outstanding journal Agronomy (JCR, Q1) is organizing this Special Issue, which will focus on molecular responses to and management strategies for crop stress. Manuscripts related to crops’ responses to biotic and abiotic stresses at the molecular level and the management of strategies for crop stress are welcomed and encouraged for submission to the Special Issue, especially these manuscripts that report findings or advances on the employment of CRISPR-cas9 gene editing; RNAi; traditional transgenic techniques; and microbiome tools to improve the performance of wheat, rice, maize, tomato, soybean, or rape seed under abiotic stress conditions such as heat, cold, salinity, flooding, low oxygen, nutrient deficiency, low pH, heavy metals, and biotic stress conditions, for instance, pathogens and pests. In short, any manuscript worldwide related to the topic of the Special Issue is welcomed.

The ubiquitin-specific protease (UBP) family represents a type of deubiquitinase (DUB) that plays a significant role in plant abiotic stress responses, growth, and development. Although UBP genes have been characterized in many species, a genome-wide systematic analysis and the potential functions under abiotic stresses have not yet been reported in rice (Oryza sativa L.). In this study, we identified 21 UBP gene family members in the genome of rice, all of which had UCH domains containing short but highly conserved Cys-box and His-box. The DUF4220 and DUF594 domains, which are found in monocotyledonous plants, were unique. Phylogenetic analysis suggested that OsUBP7 and OsUBP12 genes had the closest genetic relationships with AtUBP12 and AtUBP13, implying that OsUBP7 and OsUBP12 might have similar biological functions to AtUBP12 and AtUBP13. Synteny analysis revealed that OsUBP genes were expanded through segmental duplication under purifying selection. Meanwhile, they had closer evolutionary relationships with monocotyledonous plants. Additionally, all OsUBP genes had an ABRE cis-element, which was related to abscisic acid (ABA) stress hormone response. Protein interaction analysis suggested that OsUBP22 might modulate gene regulation through OsGCN5- and OsADA2-mediated chromatin modification, and OsUBP10 might regulate salt stress through modulating OsDNA2_4 stability. Specifically, the expression profiles and the transcriptional levels of 11 representative OsUBPs suggested the potential important functions of OsUBP9 and OsUBP17 under drought and cold stresses. Taken together, our study provided a systematic analysis of OsUBPs and preliminarily explored their potential roles under abiotic stresses. Our results lay a foundation for further research on the functions of the OsUBP gene family under abiotic stresses. Full article
