In order to understand the characteristics of Genetic resources of Kazakh horses in Xinjiang,their body size,phenotypes and coat colors were investigated and analyzed using the methods of resources survey and body size measurement. The results showed that the coat color of Kazakh horses in Xinjiang is very rich,covering more than 90% of the world＇s horse coat colors. The influencing factors of Kazakh horse body size data might include the environment and geographical distribution of Kazakh horses. The gap between Xinjiang Kazakh horse and Kazakhstan Kazakh horse was relatively large,which was related to the degree of breeding.There were some differences in the appearance of Kazakh horses between Altay and Ili regions with different ecological environment. The Kazakh horses in Altay were relatively strong in size,well developed in coat and long hair,long and dense in fuzz in winter,and rich in coat color. But the Kazakh horses in Ili were compact in size,less in coat than those in Altay,and have a single coat color.

Wild plants represent relatively unexplored resource of high economic potential,especially as an alternative to developing new crops and,even more relevant,for improving existing crops and contributing to nutrition and health.The wild species M alpighia mexicana(manzanita)has a wide tradition of food,medicinal and ornamental use in Mexico.It is part of the American-origin group of tropical shrubs that produce edible red fruits,such as A cerola,which is considered the most important natural source of vitamin C in the world.Given the role played by M.mexicana in Mexico,and particularly in Barranca del Río Santiago(Santiago River Canyon),we modelled its potential distribution in both geographical areas.We used species'records from databases,local herbaria and records collected by the authors as well as climatic variables representing long term average,variability and extreme conditions of temperature and precipitation.To fit the models we used the modelling algorithm Maxent and selected an adequate configuration by testing a range of model complexity settings.The results indicate a clear species preference for warm-dry tropical forest,most extensively in the Balsas river depression and the central valleys of Oaxaca.The probability of the species presence in the western region was also high,although the probability was also high for smaller surface areas,such as the region of Santiago river canyons,which are covered by warm-dry tropical forests.

Lentil(Lens culinaris Medik.), a diploid(2n = 14) with a genome size greater than 4000 Mbp, is an important cool season food legume grown worldwide. The availability of genomic resources is limited in this crop species. The objective of this study was to develop polymorphic markers in lentil using publicly available curated expressed sequence tag information(ESTs). In this study, 9513 ESTs were downloaded from the National Center for Biotechnology Information(NCBI) database to develop unigene-based simple sequence repeat(SSR) markers. The ESTs were assembled into 4053 unigenes and then analyzed to identify 374 SSRs using the MISA microsatellite identification tool. Among the 374 SSRs, 26 compound SSRs were observed.Primer pairs for these SSRs were designed using Primer3 version 1.14. To classify the functional annotation of ESTs and EST–SSRs, BLASTx searches(using E-value 1 × 10-5) against the public UniP rot(http://***/) and NCBI(http://www.***.nlh.***.gov/) databases were performed. Further functional annotation was performed using PLAZA(version3.0) comparative genomics and GO annotation was summarized using the Plant GO slim category. Among the synthesized 312 primers, 219 successfully amplified Lens DNA. A diverse panel of 24 Lens genotypes was used to identify polymorphic markers. A polymorphic set of 57 markers successfully discriminated the test genotypes. This set of polymorphic markers with functional annotation data could be used as molecular tools in lentil breeding.

Information on the center of genetic diversity of soybean（Glycine max） will be helpful not only for designing efficient strategies for breeding programs, but also for understanding the domestication and origin of this species. Here, we describe an analysis of genetic diversity based on simple-sequence repeat（SSR） variations within a core collection of 2 111 accessions of Chinese soybean landraces. Prior to the diversity assessment, the geographic origin of each accession was mapped. The map was then divided into grids each 2.5° in latitude and 5° in longitude. We found two regions that had higher number of alleles（NA） and greater polymorphic information content（PIC） values than the others. These regions are adjacently located within grid position of 30°–35°N×105°–110°E, which includes the valley of the middle and lower reaches of the Wei River, and the valley of the upper reaches of the Hanjiang River. It was also observed that in many regions, genetic diversity decreased with the increase in distance from the center. Another region, in northern Hebei Province（115°–120°E×40°–42.5°N）, was observed having higher diversity than any surrounding regions, indicating that this is a sub-center of soybean diversity. Based on the presented results, the domestication and origin of soybean are also discussed.

Ethylene plays essential roles in plant growth, development and stress responses. The ethylene signaling pathway and molecular mechanism have been studied extensively in Arabidopsis and rice but limited in peanuts. Here, we established a sand-culture method to screen pingyangmycin mutagenized peanut lines based on their specific response to ethylene(“triple response”). An ethylene-insensitive mutant, inhibition of peanut hypocotyl elongation 1(iph1), was identified that showed reduced sensitivity to ethylene in both hypocotyl elongation and root growth. Through bulked segregant analysis sequencing, a major gene related to iph1, named AhIPH1, was preliminarily mapped at the chromosome Arahy.01, and further narrowed to a 450-kb genomic region through substitution mapping strategy. A total of 7014 genes were differentially expressed among the ACC treatment through RNA-seq analysis, of which only the Arahy.5BLU0Q gene in the candidate mapping interval was differentially expressed between WT and mutant iph1. Integrating sequence variations, functional annotation and transcriptome analysis revealed that a predicated gene, Arahy.5BLU0Q, encoding SNF1 protein kinase, may be the candidate gene for AhIPH1. This gene contained two single-nucleotide polymorphisms at promoter region and was more highly expressed in iph1 than WT. Our findings reveal a novel ethylene-responsive gene, which provides a theoretical foundation and new Genetic resources for the mechanism of ethylene signaling in peanuts.

　　Germplasm is the foundation of any crop improvement process. The success of research in establishing PCR-based genetic maps,developing genetic stocks and tool-materials for genomic studies, creating specially-aimed materials, and even training high level educated specialists denpends in large part on the availability of diversity of Genetic resources.Cotton germplam also plays very important role in the genomic study.　　……

Lima bean is a legume belonging to Fabaceae family cultivated for edible seeds known to generic name of “haricot”. In Côte d’Ivoire, it’s cultivated on small scale in rural zone by local farmers. The main objective of this study was to document and collect local varieties of Lima beans (Phaseolus lunatus) grown in Côte d’Ivoire in order to define efficient strategies for better conservation, preservation and improvement of its Genetic resources. Investigations were carried out in seventeen localities of Côte d’Ivoire from November 2018 to September 2020. A total of 433 accessions were collected. Based on seed coat color, nineteen morphological types were identified. The length of seeds is ranged from 10 mm to 23 mm. The width of seeds varies from 7 mm and 15 mm. The 100-Seeds-weight are ranged from 31 g to 120 g. Comparison using analysis of variance (ANOVA) showed a significant difference between the nineteen morphological types of common bean. Two morphological types were observed: large seed cultivars and small seed cultivars. Data showed that the species studied have a good market potential. Thus, their promotion can contribute to the economic well-being of farmers due to their cultural and culinary importance.
