Crocus sativus, the saffron crocus, is source of saffron, which made from dried stigmas plant. It a male-sterile triploid lineage that ever since its origin has been propagated vegetatively. Its mode evolution and area are matters long-lasting debates. Here we analyzed chloroplast genomes genome-wide DNA polymorphisms obtained through genotyping-by-sequencing (GBS) to infer parent C. sativus. These data were complemented by genome size measurements analyses nuclear single-copy genes. We...

The internal transcribed spacer (ITS) region (ITS1, 5.8S rDNA, ITS2) represents one of the most popular molecular markers in phylogenetics. number investigations revealing high degrees intra-individual polymorphism connected with presence pseudogenic ITS regions is on increase. Studies including can lead to erroneous phylogenetic trees and false taxonomic conclusions. For their recognition, we focus rDNA as functional part this region, which also affected by degeneration processes. We...

Spring crocuses, the eleven species within Crocus series Verni (Iridaceae), consist of di- and tetraploid cytotypes. Among them is a group polyploids from southeastern Europe with yet-unclear taxonomic affiliation. Crocuses are generally characterized by complex dysploid chromosome number changes, preventing clear correlation between these numbers ploidy levels. To reconstruct evolutionary history particularly its polyploid lineages associated C. heuffelianus, we used an approach combining...

Hordeum bulbosum, the closest relative of barley (H. vulgare), is an important source resistance genes for cereals in Triticeae. This perennial and mainly outcrossing species occurs with two cytotypes: diploids thrive western central parts Mediterranean, while autotetraploids extend from Greece eastwards to Asia. To elucidate H. bulbosums origin, colonization patterns, population relationships, distinctions between cytotypes, we determined ploidy performed genotyping-by-sequencing analyses...

ABSTRACT The boreal forests of central and eastern Siberia, dominated by larches, are challenged increasingly harsher continental conditions more frequent droughts. Despite the crucial ecosystem services provided these Siberian forests, major stressors driving selective factors as well genetic adaptation mechanisms larches still unknown. Here we present a landscape genomics study on 243 individuals dominant larch tree species, Larix gmelinii L. cajanderi . We assessed genotype‐environment...

The allopolyploid complexes in Crocus series Verni represent taxonomic challenges due to their variable or mostly overlapping morphology with one parental species. Moreover, diploid ancestors remain unidentified, even genome-wide SNP data. One such case, collected from the southeasternmost point of series’ geographical distribution, is herein characterised and described as a new species, C. bachofenii. This study integrates phylogenomics cytogenetics infer origin bachofenii establish its...

Over more than 80 years, the collections of German Federal Ex Situ Genebank for Agricultural and Horticultural Crops have grown to around 152,000 accessions 3,000 species preserved at three locations: Gatersleben, Groß Lüsewitz Malchow/Poel. More 96% material is stored as desiccation-tolerant orthodox seeds according active–base–safety (A-B-S) replicate approach -18°C. Almost 70,000 freshly regenerated safety replicates are in Svalbard Global Seed Vault. However, 4% (2,000 field, vitro 2,500...

Abstract Wild plants can contribute valuable genes to their domesticated relatives. Fertility barriers and a lack of genomic resources have hindered the effective use crop-wild introgressions. Decades research into barley’s closest wild relative, Hordeum bulbosum , grass native Mediterranean basin Western Asia, yet manifest themselves in release cultivar bearing alien genes. Here, we construct pangenome bulbous barley comprising ten haplotype-resolved genome sequence assemblies....

The post-Miocene climatic histories of arid environments have been identified as key drivers dispersal and diversification. Here, we investigate how history correlates with the historical biogeography Atacama Desert genus Cristaria (Malvaceae). We analyze phylogenetic relationships by using next-generation sequencing (NGS), molecular clock dating, Dispersal Extinction Cladogenesis Bayesian sampling approaches. employ a novel way to identify biogeographically meaningful regions well rarely...

Recent phylogenetic analyses proved several infrageneric units within the genus Crocus to be para- or polyphyletic. In an attempt arrive at a system of that closely reflects species relationships, we provide here phylogenetic, morphometric, geographic, and nomenclatorial data for narrower-defined, monophyletic series Reticulati. We sequenced ETS ITS regions nuclear ribosomal DNA in 9 Reticulati 19 outgroup species. Three chloroplast loci (trnL-F, rps16-trnQ, matK-trnK) were newly defined 1...

Recent phylogenetic investigations on the genus Crocus proved several infra-generic units predominantly within section Nudiscapus to be para- or polyphyletic even at infra-specific level. In particular, 23 “subspecies” of C. biflorus Mill. turned out a assemblage grouping in very different clades and sub-groups. addition, they were established under binomial biflorus, not yet typified. As first step, we neotypified this name. Then, through phylogeny based ETS region nuclear ribosomal (nr)...

Abstract The Irano‐Turanian (IT) floristic region is considered an important center of origin for many taxa. However, there a lack studies dealing with typical IT genera that also occur in neighboring areas. species‐rich monocot genus Gagea Salisb. shows diversity and distribution adjacent regions, therefore representing good study object to investigate spatial temporal relationships among its areas (East Asia, Euro‐Siberia, Himalaya, Mediterranean). We aimed at (a) testing the major...
