Domesticated species are impacted in unintended ways during domestication and breeding. Changes the nature intensity of selection impart genetic drift, reduce diversity, increase frequency deleterious alleles. Such outcomes constrain our ability to expand cultivation crops into environments that differ from those under which occurred. We address this need chickpea, an important pulse legume, by harnessing diversity wild crop relatives. document extreme domestication-related bottleneck...
Current food systems are challenged by relying on a few input-intensive, staple crops. The prioritization of yield and the loss diversity during recent history domestication has created contemporary crops cropping that ecologically unsustainable, vulnerable to climate change, nutrient poor, socially inequitable. For decades, scientists have proposed as solution address these challenges global security. Here, we outline possibilities for new era crop domestication, focused broadening palette...
Summary Humans have domesticated diverse species from across the plant kingdom, yet much of our foundational knowledge domestication has come studies investigating relatively few most important annual food crops. Here, we examine impacts on genetic diversity in a tropical perennial fruit species, mango ( Mangifera indica ). We used restriction site associated DNA sequencing to generate genomic single nucleotide polymorphism SNP ) data 106 cultivars seven geographical regions along with 52...
To estimate genetic diversity within and between 10 interfertile Cicer species (94 genotypes) from the primary, secondary tertiary gene pool, we analysed 5,257 DArT markers 651 KASPar SNP markers. Based on successful allele calling in 2,763 624 that are polymorphic genotypes pools were analyzed further. STRUCTURE analyses consistent with 3 cultivated populations, representing kabuli, desi pea-shaped seed types, substantial admixture among these groups, while two wild populations observed...
ABSTRACT Woody perennial plants make up nearly half of plant diversity and represent one‐third the world's major crop species, yet effective strategies to maintain preserve these important species require additional attention. The majority conservation programs focus on seed storage; however, seeds many woody are difficult in banks because they recalcitrant. In addition, most crops clonally propagated, seed‐based efforts miss clonal lineages that form foundation agriculture. often best...
Abstract Anacardiaceae is an ecologically and economically important plant family of about 200 species in 32 genera the Neotropics. The particularly diverse leaf architecture fruit morphology, making it a model to study evolution structural diversity as correlates with lineage diversification. This primary reason 11 Neotropical are monotypic that so many recognized Anacardiaceae. economic value driven by global markets for cashews, mangoes, pistachios, but there great potential its medicinal...
Mango is a globally important tropical fruit but lacks genomic tools to support cultivar identification and enable breeding efforts. Assessing the genetic diversity relatedness of mango germplasm essential for identifying genetically distant parents with favorable agronomic traits produce hybrid populations enabling selection improved cultivars. We thus genotyped 1915 accessions from United States, Senegal, Thailand, Australia 272 single nucleotide polymorphism (SNP) markers over 520,000...
Abstract Management and distribution of experimental data from prebreeding projects is important to ensure uptake germplasm into breeding research programs. Being able access share this in standard formats essential. The adoption a common informatics platform for crops that may have limited resources brings economies scale, allowing components be used across multiple species. close integration such with commonly software, visualization, analysis tools reduces the barrier entry researchers...
The most remarkable feature of our planet is the diversity its life forms, ranging from viruses and nanobacteria to blue whales giant sequoias satanic leaf-tailed geckos leafy seadragons (look them up!). Life found in essentially all environments on earth, number species living many times greater than we could have imagined a century ago. A well-regarded estimate pegs eukaryotic earth at 8.7 million (±1.3 million), which fewer 15% are currently described (Mora et al., 2011). prokaryotes less...
Societal Impact Statement Given the rapidly increasing drought and temperature stresses associated with climate change, innovative approaches for food security are imperative. One understudied opportunity is using feral crops—plants that have escaped persisted without cultivation—as a source of genetic diversity, which could build resilience in domesticated conspecifics. In some cases, however, plants vigorously compete crops as weeds, challenging security. By bridging historically siloed...
Abstract Sunflower seeds (technically achenes) are characterized by a wide spectrum of sizes, shapes, and colors. These traits genetically correlated with the branching plant architecture loci, which were introgressed into restorer lines to facilitate efficient hybrid production. To break this genetic correlation between seed traits, high resolution mapping genes that regulate is necessary. Recent progress in genomics permits acquisition comprehensive genotyping data for large diversity...
Molecular Ecology continues to be one of the most influential journals in ecology and evolution. It ranks second overall impact among or evolution as measured by Google Scholar's h5-index, which is h-index for articles published over past five years. also highly evolutionary biology h5-median (third both disciplines), median number citations that make up a journal's h5-index. In terms Impact Factor (IF), 7th out 50 according Clarivate. our view, h5-index offer more accurate statistically...
Abstract Homoploid hybridization is known to play an important role in the evolution of plants, including many crop species, but can have different outcomes introgression between parental taxa and formation new evolutionary lineages. We investigate occurrence consequences economically tree Mangifera indica (mango) two congeneric species Southeast Asia. A total 90 samples hybrid M. odorata its taxa, foetida , along with 65 a newly proposed hybrid, casturi putative quadrifida were sampled...
Few plants have captured the imagination and palettes of world like those which bear edible fruits, providing novel insights into relationships between people. This special collection reviews research highlights unique challenges opportunities we face when studying, breeding, working to conserve these species. The 18 articles included here examine fruiting across diverse scales topics, from genome global sustainability, fruit morphology species' geographic distributions, yet they showcase...
Functional recovery of secondary tropical forests Tropical disappear rapidly through deforestation but also have the potential to regrow naturally succession. To advance successional theory, it is essential understand how these and their assembly vary across broad spatial scales. Here I present some main findings [2ndFOR research network on forest succession](https://www.2ndFOR.org) that provides a long-term perspective succession using >100 chronosequence sites tropics. We synthesize...
