Special Issue Information

Dear Colleagues,

Agricultural crop productivity has been threatened by constant abiotic environmental stressors such as drought, salinity, flooding, low or high temperature, UV-B radiation, nutrient deficiency, and heavy metal toxicity, et al. To deal with those abiotic stresses, crops activate/repress complex signaling cascades consisting of a serial of stress-related genes/proteins, thus enabling their rapid physiological reactions to facilitate plant adaptive growth and development. Hence, the understanding of molecular mechanisms underlying the crop plants responses to various abiotic environmental stresses would advance our genetic toolbox and help develop strategies for crop improvement and modern genetic breeding.

The main goal of this Special Issue is to provide novel and deeper insights into the adaptions of horticultural crops to different abiotic stresses at the cellular, tissue, organ, and whole-plant level. We aim to provide multiple breeding strategies to develop abiotic stress-resilient traits and crops based on the understanding of stress responsive regulatory networks. We encourage authors to submit enlightening reviews addressing essential research gaps in the field. Original research on validating gene function from multiple aspects including, but not limited to, plant genomics, multi-omics resources, transcriptional/post-transcriptional regulations, translational/post-translational regulations, and plant–microbe interactions, which will help to elucidate the molecular mechanisms of horticultural crops’ adaptions to abiotic environmental stresses, are also welcome.

Salinity stress prominently limits cucumber growth and productivity. However, the mechanism underlying salinity response mediated by the C-TERMINALLY ENCODED PEPTIDE (CEP) peptide in cucumber primary root remains largely unclear. In this study, we show that salinity prominently inhibits cucumber primary root growth, and CsCEP gene expression is differentially induced by salinity. We further demonstrate that the exogenous application of synthetic CsCEP3 peptide partially suppresses salinity-triggered growth inhibition in cucumber primary root, although CsCEP3 peptide itself shows no obvious effect on cucumber primary root growth under normal conditions. Our transcriptomic and qRT-PCR data further reveal that CsCEP3 peptide may modulate gene expression related to abscisic acid (ABA) signaling pathway, reactive oxygen species (ROS) production, and slat-responsive transcription factors to attenuate the inhibitory effect of salinity on cucumber primary root growth. Taken together, our work provides a fundamental insight into CEP peptide-mediated cucumber salinity adaptation. Full article

As a molecular chaperone, HSP70 is widely involved in complex activities in plants. Under high temperature, drought, high salt, low temperature, heavy metals, and other stresses, HSP70 is rapidly synthesizes, stabilizes protein and biological macromolecular structures, and improves the stress resistance of plants. In this study, 83 ClHSP70 genes in Chrysanthemum lavandulifolium were identified based on the published Chrysanthemum lavandulifolium genome database. The genes were divided into six clusters based on a phylogenetic analysis, and the gene structures, conserved motifs, and functional domains were relatively conserved. Only two collinear genes were observed, and they formed a pair of duplicating genes. Multiple abiotic stress and phytohormone response elements were observed on the ClHSP70 promoter, such as temperature, drought, methyl jasmonate, abscisic acid, and other stress-related elements, and CpG islands were found on some ClHSP70 promoters, suggesting that they may be related to methylation modifications. Tissue expression analysis showed that the ClHSP70 genes were highly expressed in the roots. In addition, the gene expression changed significantly after 1 h of heat treatment and plays an important role in plant responses to temperature stress. The results of this study provide insights on the ClHSP70 gene family members and a theoretical basis for further research on functional analyses of the ClHSP70 gene family. Full article
