Peanut (Arachis hypogaea L.) is a major oilseed crop, which is cultivated in tropical and subtropical regions of the world. It is an allotetraploid species (AABB, 2n = 4x = 40, genome size of 2.7 Gb) that derived from hybridization between the diploids A. duranensis (AA) and A. ipaensis (BB) in southern Bolivia to northern Argentina region about thousands of years ago. However, artificial selection during cultivation has resulted in narrow genetic base, with striking yield, but poor biotic and abiotic resistance. This presents a key vulnerability and a fundamental limitation to the genetic improvement of peanut. To overcome these limitations, landraces and wild species in Arachsis have been used as a strategic source of diversity for peanut improvement.
The sequencing of several peanut genomes, including allotetraploid cultivated peanuts and two diploid ancestral species, coupled with rapid advances in bioinformatics, provided powerful tools for detailed studies of functional genomics. However, current studies in the field of phenomics are mainly empirically based. Traditional crop phenotyping methods are labour intensive, time-consuming, subjective, and frequently destructive to plants. The high throughput analysis of peanut traits, including growth and development, seed quality, abiotic and biotic resistance, is a major bottleneck, which restricts functional genomics studies and peanut breeding. Therefore, it is necessary that efficient and accurate phenotypic data could be linked to genomics information for the improvement of peanut research.
The goal of this Research Topic is to bring forward the latest research in peanut, to address gaps in areas of plant physiology, genetics, functional genomics, phenomics and germplasm in the Arachis genus. This information would bring a better understanding of the physiology growth and development, seed quality, abiotic and biotic response of peanut, thereby leading to the sustainable production of this oilseed crop.
We welcome submissions on the following research themes but not limited to:
• Evaluation of germplasm and genetic diversity in Arachsis
• High-Throughput Phenotyping analysis
• Genetic basis and QTLs/genes mapping for important breeding traits, including oil, protein and other seed related traits
• Functional analysis of genes and genomics research
• Advances in genetic improvement research related to yield, quality and stress tolerance in Arachsis
