Special Issue Information

Dear Colleagues,

Climate change is the result of the degradation of our natural resources, mainly due to the dramatic population increase. This scenario will compromise food security in marginal environments by inhibiting crop production. Applied molecular biology and biotechnology have the potential to yield a system-level perspective on plant biotic and abiotic stress response mechanisms through the characterization of stress-inducible genes, regulatory networks and biochemical pathways. A number of studies have adopted NGS (next-generation sequencing)-based profiling of the transcriptome, proteomic or metabolomic studies to identify genes involved in abiotic and biotic stress tolerance.

These advancements will lead to an array of new crops tailored to abiotic stresses and adapted to marginal environments. Therefore, it is essential to explore the ongoing genomic tools and latest biotechnological developments for understanding the various aspects of crop abiotic stress tolerance in marginal lands.

The present Special Issue, “Applied Molecular Biology and Biotechnology for Crop Improvement in Marginal Environments”, addresses the progress made in molecular and biotechnological approaches with the aim of gathering the most recent scientific knowledge for their applications in growing crops on marginal affected lands. In this broad context, we invite investigators/researchers to submit original research articles, reviews and mini reviews, opinions, and perspectives on these thematic areas. The range of research topics may include, but are not limited to, molecular/conventional breeding, linkage mapping and GWAS, transgenesis, application of omics approaches, RNA-Seq, epigenetics and computational approaches for diversified crop production under abiotic stress and marginal land conditions.

The so-called disruptive technologies, in particular infotech and biotech, will have a huge transformative potential role to cope with climate change in marginal lands in the near future.

Chickpea is widely grown in rainfed areas of developing countries because of its nutritional abundance and adaptability. To overcome the environmental effect of drought on yield, a characteristic-linked selection strategy is proved as well-thought-out and advantageous for the development of drought-tolerant cultivars. To precisely understand the contribution of various physio-biochemical and yield-attributing traits toward drought tolerance in chickpea (Cicer arietinum L.), forty chickpea genotypes were evaluated in the years 2020–2021 and 2021–2022 under normal irrigated as well as drought-stressed conditions. Among the studied genotypes, genotype ICC4958 retained the highest chl content (0.55 mg g−1 FW), minimal electrolyte leakage, and superoxide dismutase (1.48 U/mg FW) and peroxidase (2.21 µmol/min/g FW) activities while cultivar JG11 maintained the maximum relative water content and proline accumulation. The principal-component-based biplots prioritized the physio-biochemical and yield-accrediting characteristics based on their association significance and contribution to terminal drought tolerance. Under drought stress, grain yield per plant was depicted to have a strongly positive association with canopy temperature depression, catalase, superoxide dismutase, and peroxidase activities as well as total soluble sugar, proline, and chlorophyll content, along with the numbers of pods and biological yield per plant. These identified physio-biochemical and yield-attributing traits can be further deployed to select drought-tolerant chickpea genotypes for the breeding of climate-smart chickpea genotypes.
