Although applied over extremely short timescales, artificial selection has dramatically altered the form, physiology, and life history of cultivated plants. We have used RNAseq to define both gene sequence and expression divergence between cultivated tomato and five related wild species. Based on sequence differences, we detect footprints of positive selection in over 50 genes. We also document...
Beta vulgaris genus comprises wild and cultivated subspecies. The “maritima” subspecies is formed by wild or weedy accessions, well adapted to low-water potential environments; it was previously shown that B. vulgaris ssp. maritima has mechanisms of osmotic adjustment more effective than the cultivated B. vulgaris ssp. vulgaris. The response to a progressive lowering of soil potential was compa...
Cicer reticulatum L. is the wild progenitor of the fourth most important legume crop chickpea (C. arietinum L.). We assembled short-read sequences into 416 Mb draft genome of C. reticulatum and anchored 78% (327 Mb) of this assembly to eight linkage groups. Genome annotation predicted 25,680 protein-coding genes covering more than 90% of predicted gene space. The genome assembly shared a substa...
Shiikuwasha (Citrus depressa Hayata) is distributed from the South-west of the Japanese archipelago to Taiwan. In this study, re-sequencing against the orange (C. sinensis (L.) Osbeck) chloroplast genome was applied to one superior landrace of Shiikuwasha cultivated in Oku ward, Okinawa, Japan. The chloroplast genome of the landrace was estimated to comprise 160,118 bp, including 48 indels and ...
In this experiment 36 accessions of seven species of Brassica genus were evaluated under field condition (for study of genetic variation) and under laboratory condition (for study seedling drought tolerance) in 2012 at Isfahan university of technology research farm. The statistic design in field was completely randomized block with three replications. Results of field assessments were suggestiv...
Reliable estimations of drought tolerance in wild plant populations have proved to be challenging and more accessible alternatives are desirable. With that in mind, an ecological diversity study was conducted based on the geographical origin of 104 wild common bean accessions to estimate drought tolerance in their natural habitats. Our wild population sample covered a range of mesic to very dry...
The origin and domestication of rice has been a subject of considerable debate in the post-genomic era. Rice varieties have been categorized based on isozyme and DNA markers into two broad cultivar groups, Indica and Japonica. Among other well-known cultivar groups Aus varieties are closer to Indica and Aromatic varieties including Basmati are closer to Japonica, while deep-water rice varieties...
in order to study the genetic diversity among 35 accessions of ae. triuncialis l. from17 ssr loci of 56 primer pairs originated from a and d genomes of bread wheat were used. seventy one fragments amplified totally and 68 of them were polymorph between genotypes. allele number ranged from 1 to 8 with average 4.18 per locus. pic value of markers was from 0.593 (xgwm-30-2d, xgwm-383-3d, xgwm-654-...
Chinese ginseng (Panax ginseng Meyer) is a medicinally important herb and plays crucial roles in traditional Chinese medicine. Pharmacological analyses identified diverse bioactive components from Chinese ginseng. However, basic biological attributes including domestication and selection of the ginseng plant remain under-investigated. Here, we presented a genome-wide view of the domestication a...
