Introduction
Virginia-type peanut, Arachis hypogaea subsp. hypogaea , is the second largest market class of peanut cultivated in the United States. It is mainly used for large-seeded, in-shell products. Historically, Virginia-type peanut cultivars were developed through long-term recurrent phenotypic selection and wild species introgression project...
In this chapter, we introduce the main components of the Legume Information System (https://legumeinfo.org) and several associated resources. Additionally, we provide an example of their use by exploring a biological question: is there a common molecular basis, across legume species, that underlies the photoperiod-mediated transition from vegetativ...
Significance
A great challenge for humanity is feeding its growing population while minimizing ecosystem damage and climate change. Here, we uncover the global benefits arising from the introduction of one wild species accession to peanut-breeding programs decades ago. This work emphasizes the importance of biodiversity to crop improvement: peanut...
Key message
A major locus for spontaneous haploid genome doubling was detected by a case–control GWAS in an exotic maize germplasm. The combination of double haploid breeding method with this locus leads to segregation distortion on genomic regions of chromosome five.
Abstract
Temperate maize (Zea mays L.) breeding programs often rely on limited g...
Legumes, comprising one of the largest, most diverse, and most economically important plant families, are the subject of vibrant research and development worldwide. Continued improvement of legume crops will benefit from the recent proliferation of genetic (including genomic) resources; but the diversity, scale, and complexity of these resources pr...
Like many other crops, the cultivated peanut (Arachis hypogaea L.) is of hybrid origin and has a polyploid genome that contains essentially complete sets of chromosomes from two ancestral species. Here we report the genome sequence of peanut and show that after its polyploid origin, the genome has evolved through mobile-element activity, deletions...
As sequencing prices drop, genomic data accumulates-seemingly at a steadily increasing pace. Most genomic data potentially have value beyond the initial purpose-but only if shared with the scientific community. This, of course, is often easier said than done. Some of the challenges in sharing genomic data include data volume (raw file sizes and num...
The future of agricultural research depends on data. The sheer volume of agricultural biological data being produced today makes excellent data management essential. Governmental agencies, publishers and science funders require datamanagement plans for publicly funded research. Furthermore, the value of data increases exponentially when they are pr...
LIS (legumeinfo.org) is a resource for trait genetics and comparative genomics for legumes. The site hosts annotated genomes for nine species: common bean, chickpea, pigeonpea, Medicago truncatula, Lotus japonicus, mungbean, soybean (SoyBase.org) and two Arachis species (PeanutBase.org). A major effort at LIS is to leverage data from information-ri...
Legume Information System (LIS), at http://legumeinfo.org, is a genomic data portal (GDP) for the legume family. LIS provides access to genetic and genomic information for major crop
and model legumes. With more than two-dozen domesticated legume species, there are numerous specialists working on particular
species, and also numerous GDPs for these...
Here we report the draft genome sequence of perennial ryegrass (Lolium perenne), an economically important forage and turf grass species widely cultivated in temperate regions worldwide. It is classified along with wheat, barley, oats and Brachypodium distachyon in the Pooideae sub-family of the grass family (Poaceae). Transcriptome data was used t...
Background
Perennial ryegrass is a highly heterozygous outbreeding grass species used for turf and forage production. Heterozygosity can affect de-Bruijn graph assembly making de novo transcriptome assembly of species such as perennial ryegrass challenging. Creating a reference transcriptome from a homozygous perennial ryegrass genotype can circumv...
The development of next-generation sequencing technologies has made sequencing an affordable approach for detection of genetic variations associated with various traits. However, the cost of whole genome re-sequencing still remains too high to be feasible for many plant species with large and complex genomes. Recent developments in strategies for t...
Perennial ryegrass (Lolium perenne L.) is one of the most important forage and turf grass species of temperate regions worldwide. Its mitochondrial genome is inherited maternally and contains genes that can influence traits of agricultural importance. Moreover, the DNA sequence of mitochondrial genomes has been established and compared for a large...
Perennial ryegrass (Lolium perenne L.) is an outbreeding diploid species and one of the principal forage crops used in temperate agriculture. A sequenced genome will both enhance efforts to understand the genetic control of important traits, and accelerate the application of molecular breeding strategies to forage grasses. Sequencing efforts have f...
Lolium perenne (perennial ryegrass) is an outbreeding diploid species with an estimated genome size of 2,695 Mbp. It is the principal forage species used in temperate agriculture and therefore a prime candidate for genome sequencing. A sequenced genome will both enhance efforts to understand the genetic control of important traits, and accelerate t...
Perennial ryegrass (Lolium perenne L.) is an important grass species for both forage and amenity purposes for temperate regions worldwide. It is envisaged that breeding efforts may be enhanced with the assistance of new breeding technologies such as genomic selection. A major step towards genomic selection will be the availability of a reference ge...

AgBioData (https://www.agbiodata.org) is a consortium of people working at agricultural biological databases, data archives and knowledgbases who strive to identify common issues in database development, curation and management, with the goal of creating database products that are more Findable, Accessible, Interoperable and Reusable. We strive to promote authentic, detailed, accurate and explicit communication between all parties involved in scientific data.
