In the new era of high-through technologies combined with decades of molecular-level research, plant genetics has reached far beyond what were once thought to be its boundaries. Technological advances broadened our perspectives to include new dimensions of molecular pathways and networks defining plant responses and tolerance mechanisms to abiotic stresses (such as temperature, salinity, and desiccation). From genomic and transcriptomic to metabolic scales, scientists are now able to specify and explore complex response mechanisms at the molecular level, including the discovery of new genes, identification and exploration of gene expression modulators, cis-element regulators, promotor inducers, post-transcriptional and post-translational regulation, and protein secretion and degradation. Plant responsiveness and tolerance to abiotic stress have been enriched and diversified during the evolution of land plants. The polygenic nature of abiotic stress tolerance may be related to gene gain and loss in Embryophytes (i.e., bryophytes and tracheophytes). Environmental pressures on wild species (i.e., global climate change), and the relatively recent breeding of cultivated crops to favor mutations beneficial to agriculture result in continuous changes in plant genetic resources, including the development of new varieties and genotypes.
Now more than ever, exploring new solutions and approaches in accordance with human food security and gap-reduction is a central focus for scientific research, especially under the stresses that are emerging due to global climate changes. Comparative studies over several groups of Embryophytes (wild and/or cultivated) can widen our understanding of the genetic bases and the evolutionary mechanisms of molecular pathways and networks that contribute to plant abiotic stress tolerance. In this context, this Research Topic's purpose is to compile recent contributions from the scientific community through the submission of high-quality original research manuscripts or review articles, or any topic related to the evolution of abiotic stress responses in land plants, including all embryophytes whether vascular (tracheophytes) or non-vascular (bryophytes).
Regardless of the species type, origin, endemic level, wildness, or economic importance, scientists with an interest in the evolution of genes responsive to specific abiotic stresses (such as drought, salts, or heat) in land plants are encouraged to submit. Contributions at the genomic, transcriptomic, and/or metabolomic levels or any related field are welcome, including the discovery of new genes, description of gene interactions, identification and exploration of gene expression modulators, cis-element regulators, promotor inducers, post-transcription & post-translation regulation, and protein degradation. As well as genetic diversity assessment, genome-wide associations, plant adaptation, molecular ecology, phylogeny, and genome/gene-family research are of interest.
