Knowledge of current genetic diversity and mating systems crop wild relatives (CWR) in the Fertile Crescent is important improvement, because western agriculture began area after cold-dry period known as Younger Dryas about 12,000 years ago these species are also genepools world's most food crops. Wild pea (Pisum sativum subsp. elatius) an source for further improvement harbouring traits useful climate change context. The structure was assessed on 187 individuals Pisum elatius from fourteen...

The origin of the agriculture was one turning points in human history, and a central part this evolution new plant forms, domesticated crops. Seed dispersal germination are two key traits which have been selected to facilitate cultivation harvesting objective study analyze anatomical structure seed coat pod, identify metabolic compounds associated with water-impermeable differentially expressed genes involved pea dormancy pod dehiscence. Comparative anatomical, metabolomics, transcriptomic...

Abstract There is growing interest in the conservation and utilization of crop wild relatives (CWR) international food security policy research. Legumes play an important role human health, sustainable production, global security, resilience current agricultural systems. Pea belongs to ancient set cultivated plants Near East domestication center remains today. Based on genome-wide analysis, P . fulvum was identified as a well-supported species, while diversity sativum subsp. elatius...

Pea, one of the founder crops from Near East, has two wild species: Pisum sativum subsp. elatius, with a wide distribution centered in Mediterranean, and P. fulvum, which is restricted to Syria, Lebanon, Israel, Palestine Jordan. Using genome analysis 11,343 polymorphic single nucleotide polymorphisms (SNPs) on set elatius (134) fulvum (20) 74 domesticated accessions (64 landraces 10 abyssinicum), we demonstrated that Ethiopian pea (P. abyssinicum) were derived different genepools....

Seed coats serve as protective tissue to the enclosed embryo. As well mechanical there are also chemical defence functions. During domestication, property of seed coat was altered including removal dormancy. We used a range genetic, transcriptomic, proteomic and metabolomic approaches determine function pea polyphenol oxidase (PPO) gene. Sequencing analysis revealed one nucleotide insertion or deletion in PPO gene, with functional allele found all wild samples, while most cultivated peas...

Soybean is an important legume crop and a leading source of dietary protein oil in animal feed, as well food for human consumption. The objective our research was to study soybean genetic resources context future self-sufficiency both nutrition. Collection 360 different accessions from various regions worldwide evaluated across four European locations during two consecutive years phenotyping trials. five most traits - plant emergence, length, content, seed yield, R8 stage were carefully...

Abstract Main conclusion We showed that wild pea seeds contained a more diverse combination of bioactive GAs and had higher ABA content than domesticated peas. Although the role abscisic acid (ABA) gibberellins (GAs) interplay has been extensively studied in Arabidopsis cereals models, comparatively little is known about effect domestication on level phytohormones legume seeds. In legumes, as other crops, seed dormancy largely or entirely removed during domestication. this study, we have...

The mature seed in legumes consists of an embryo and coat. In contrast to knowledge about the embryo, we know relatively little We analyzed gene expression during development using a panel cultivated wild pea genotypes. Gene co-expression analysis identified modules related development, dormancy, domestication. Oxidoreductase genes were found be important components developmental domestication processes. Proteomic metabolomic revealed that favored proteins involved photosynthesis protein...

Abstract Crops arose from wild ancestors and to understand their domestication it is essential compare the cultivated species with crop relatives. These represent an important source of further improvement, in particular relation climate change. Although there are about 58,000 Lens accessions held genebanks, only 1% wild. We examined geographic distribution genetic diversity lentil's immediate progenitor L. orientalis . used Genotyping by Sequencing (GBS) identify characterize...

Plant-rhizobia symbiosis can activate key genes involved in regulating nodulation associated with biological nitrogen fixation (BNF). Although the general molecular basis of BNF process is frequently studied, little known about its intraspecific variability and characteristics allelic variants. This study's main goals were to describe phenotypic genotypic variation context red clover (

Commonly studied in the context of legume–rhizobia symbiosis, biological nitrogen fixation (BNF) is a key component cycle nature. Despite its potential plant breeding and many years research, information still lacking as to regulation hundreds genes connected with plant–bacteria interaction, nodulation, fixation. Here, we compared root nodule transcriptomes red clover (Trifolium pratense L.) genotypes contrasting efficiency, found 491 differentially expressed (DEGs) between plants high low...

Bumblebees are significant pollinators for both wild plants and economically important crops. Due to the worldwide decrease in pollinators, it is crucial monitor prevalence distribution of bumblebee pathogens. Field-caught workers males were examined presence three pathogens during summer months years 2015–2020 (Bombus terrestris/lucorum) 2015–2017 lapidarius). The greatest was case Crithidia bombi, where significantly more (57%) B. terrestris/lucorum infected than (41%). Infection also...
