Special Issue Information

Dear Colleagues,

Abiotic stress, including but not limited to heavy metal pollution, drought, extreme temperature, salinity, element deficiency, etc., has an important influence on plant growth and development. Abiotic stresses affect the entire life cycle of plants, such as seed germination, flowering and fruiting. In order to adapt to abiotic stress, plants respond at different scales (genetics, physiology, morphology, function, etc.). At the same time, with the global climate changing, there will be further interaction between plants and adverse environments. Research activity on plant genetics for abiotic stress resistance not only has the aim to understand the molecular mechanisms of plant response to adverse environments, but also the basis for application (e.g., phytoremediation, resistance breeding).

In recent years, with the development of molecular and bioinformatics technology, especially gene editing and plant genomics, great progress has been made in the response of plant genes to abiotic stress. To understand the advances in plant genetics regarding abiotic stress resistance, we have launched this Special Issue. The Special Issue has a wide scope, including both mechanistic research and engineering applications. We welcome research on all aspects of abiotic stress biology, including fundamental insights into the understanding of plant responses to abiotic stresses and the use of biotechnological and other strategies to improve the resistance/tolerance of plants to abiotic stresses. Of course, related bioinformatics research (e.g., software development) is also within the scope of our publications.

Salt stress seriously reduced the yield and quality of watermelon and restricted the sustainable development of the watermelon industry. However, the molecular mechanism of watermelon in response to salt stress is still unclear. In this study, 150 mmol·L−1 NaCl was used to deal with the seedlings of salt-tolerant and salt-sensitive watermelon varieties. Physiological characteristics showed that salt stress significantly reduced the biomass of watermelon seedlings and the accumulation of K+ in roots and leaves and significantly increased the content of Na+, Cl−, and malondialdehyde (MDA). Compared with the salt-sensitive variety, the salt-tolerant variety had higher K+ accumulation, lower Cl−, Cl− accumulation, and MDA content in roots and leaves. Then, RNA-seq was performed on roots and leaves in normal culture and under 150 mmol·L−1 NaCl treatment. A total of 21,069 genes were identified by RNA-seq analysis, of which 1412 were genes encoding transcription factors (TFs). In the comparison groups of roots and leaves, 122 and 123 shared differentially expressed genes (DEGs) were obtained, respectively. Gene ontology (GO) annotation and KEGG enrichment results showed that there were many identical GO terms and KEGG pathways in roots and leaves, especially the pathways that related to sugar or energy (ATP or NADP+/NADPH). In addition, some DEGs related to salt tolerance were identified, such as plant hormone indole-3-acetic acid (IAA) and gibberellin (GA) signal transduction pathway-related genes, K+/Na+/Ca2+-related genes, lignin biosynthesis-related genes, etc. At the same time, we also identified some TFs related to salt tolerance, such as AP2-EREBP, bZIP, bHLH, MYB, NAC, OFP, TCP, and WRKY and found that these TFs had high correlation coefficients with salt tolerance-related genes, indicating that they might have a potential regulatory relationship. Interestingly, one TCP TF (Cla97C09G174040) co-exists both in roots and leaves, and it is speculated that it may be regulated by miR319 to improve the salt tolerance of watermelon. Full article
