Special Issue Information

Dear Colleagues,

Crop production is continuously threatened by diverse abiotic and biotic stresses, which severely limit grain yield and quality worldwide. Deciphering the genetic basis of agronomic traits and stress tolerance has become a core priority for modern molecular breeding. Rapid advances in genomics, GWAS, transcriptomics, and gene functional validation have greatly accelerated the identification of elite genes and molecular regulatory networks, laying a solid foundation for developing stress-resilient crop varieties with improved quality.

This Special Issue aims to collect cutting-edge studies on crop genetics, grain quality formation, and plant stress responses, which fully matches the research scope of Life focusing on molecular biology and plant science. We welcome high-quality original research papers, short communications, and comprehensive reviews that uncover genetic mechanisms in major cereal and food crops.

The potential topics include, but are not limited to:

(1) Genetic dissection of yield and quality-related traits using GWAS, QTL mapping, and pan-genome analysis;

(2) Molecular regulatory pathways of salt, drought, and nutrient stress responses in crops;

(3) Functional characterization of key genes governing stress tolerance and grain quality;

(4) Genomic-assisted breeding and elite germplasm innovation.

We look forward to receiving your valuable contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The semi-dwarfing gene Rht-D1b (formerly known as Rht2) was introduced into modern wheat breeding during the Green Revolution to reduce plant height, improve lodging resistance, and increase harvest index. In this study, two wheat (Triticum aestivum L.) lines carrying Rht-D1b (dwarf) and Rht-D1a (tall), respectively, were used to assess the role of Rht-D1b in salt tolerance through physiological and transcriptomic analyses under salt stress. Compared with Rht-D1a, Rht-D1b showed less growth inhibition, with smaller decreases in plant height, root length, and shoot biomass, as well as higher SPAD values. Rht-D1b also accumulated less Na+, had lower ROS and MDA levels, and maintained stronger POD and CAT antioxidant enzyme activities. Transcriptome analysis showed that 20 POD genes were consistently upregulated in Rht-D1b to Rht-D1a at 0, 6, and 24 h, while ion-transport- and ROS-related genes showed time-specific activation patterns linked to Na+ homeostasis, calcium signaling, and antioxidant defense. Together, these findings suggest that Rht-D1b may contribute to wheat seedling salt tolerance by improving ion homeostasis and redox balance. The salt-responsive genes identified in this study may also serve as candidates for future functional studies and wheat breeding. Full article
