Plant breeding- and genetics-based tools for food security under changing climate
Heterosis breeding is a crucial method for breaking the yield plateau in rice (Oryza sativa L.). Inter-subspecific crosses were used in rice to diversify the parental lines to harness high heterosis. We evaluated the newly developed inter-subspecific lines for agronomic and quality traits to identify promising candidates. The inter-subspecific derivatives showed substantial genetic diversity. Selection based on multiple traits identified a few superior lines that may serve as potential restorers in hybrid development.

This paper basically is about chickpea transcriptomics, which helps cope with biotic and abiotic stresses. Chickpea transcriptome research has made significant progress since the introduction of next-generation sequencing (NGS) technologies. Researchers from a wide range of disciplines have studied gene expression in reproductive and vegetative tissues by using NGS platforms, uncovering a plethora of transcripts that are unique to their development stages

This study has highlighted the significance of investigating genetic diversity in Catharanthus roseus by exploring how genetic variations influence the evolution of trait like petal color and pattern. Understanding this genetic diversity is crucial for improving plant breeding, and conservation. The research addresses the challenge of identifying meaningful genetic markers that can distinguish among cultivars and help map their evolutionary relationships. This work contributes to the broader goal of advancing our understanding of plant evolution within the Apocynaceae family.

Soybean (Glycine max) is one of the most important crop, primarily being cultivated as a substitute for high-protein meat and a source of vegetable oil. In recent years, several traditional breeding methods have increased soybean yields but are not able to meet the demands of the world’s rapidly growing population. Therefore, novel genomic techniques are required to overcome those challenges by introducing greater genetic diversity into the soybean germplasm, which will help develop multipurpose desired soybean varieties.

Chickpea (Cicer arietinum) is grown in arid climate of the southern Punjab in Pakistan. The major limits on chickpea production are poor genetic diversity, low and variable yield, and vulnerability to biotic and abiotic stressors. However, the abundance of chickpea germplasm accessions provides opportunity for improved production in a range of biotic and abiotic constraints.

Brassica juncea is farmed around the world, and varies widely in flowering time and the need for cold temperatues to trigger flowering. We used a range of molecular techniques to understand the genetics and evolution underpinning that variation, in contemporary breeds and ancestor species.

For decades, potato breeding has been hindered by high diversity and genetic complexity. We identified the individual locations of genes that contribute to potato yield, by analysing data from 14 prior studies. This knowledge will accelerate breeding programmes.

Wheat, a vital global food source, faces production limitations due to climate-induced stresses. Developing resilient cultivars is crucial. Genetic diversity aids in identifying variations for improved cultivars. This study utilised iPBS-retrotransposons to characterise wheat germplasm, yielding 170 bands. Genetic distance highlighted G9 and G60 as genetically distinct genotypes. Different methods identified three or four distinct groups of genotypes amongst the studied germplasm. This informs targeted breeding strategies for enhanced wheat varieties.

Ensuring universal food security is a crucial concern for all of humanity. Pea, as one of the most important legumes, faces many growing challenges in the light of changing climate, whereas growing superior cultivars is a key strategy to meet the ever-growing demands. Turkish pea germplasm encompasses a rich diversity that can be utilised in breeding programs, particularly among the more diverse samples, to generate cultivars adapted to new changing environments.
