Despite its economic, social, biological, and cultural importance, wild forms of the genus Phaseolus are not well represented in germplasm banks, and they are at great risk due to changes in land use as well as climate change. To improve our understanding of the potential geographical distribution of wild beans (Phaseolus spp.) from Mexico and support in situ and ex situ conservation programs, we determined the climatic adaptation ranges of 29 species and two subspecies of Phaseolus collected throughout Mexico. Based on five biotic and 117 abiotic variables obtained from different databases—WorldClim, Global‐Aridity, and Global‐PET—we performed principal component and cluster analyses. Germplasm was distributed among 12 climatic types from a possible 28. The general climatic ranges were as follows: 8–3,083 m above sea level; 12.07–26.96°C annual mean temperature; 10.33–202.68 mm annual precipitation; 9.33–16.56 W/m2 of net radiation; 11.68–14.23 hr photoperiod; 0.06–1.57 aridity index; and 10–1,728 mm/month of annual potential evapotranspiration. Most descriptive variables (25) clustered species into two groups: One included germplasm from semihot climates, and the other included germplasm from temperate climates. Species clustering showed 45% to 54% coincidence with species previously grouped using molecular data. The species P. filiformis, P. purpusii, and P. maculatus were found at low‐humidity locations; these species could be used to improve our understanding of the extreme aridity adaptation mechanisms used by wild beans to avoid or tolerate climate change as well as to introgress favorable alleles into new cultivars adapted to hot, dry environments.

“…Of the four samples clustered together in Group 1, three were also clustered similarly in molecular dendrograms. Low correlations between genetic and chemical groupings have also been reported in various studies (Agrama and Tuinstra, 2003;Iqbal et al, 2010;Pandotraet al, 2013). To our knowledge, this is the first report on the association of molecular markers with fatty acid profiles in sorghum.…”

“…Sorghum is used for food, animal feed, fibers in wallboards, fences, biodegradable packing material, and for ethanol production (Rooney and Waniska, 2000;Mehmood et al, 2008;Iqbal et al, 2010). The grain is used mostly for food in the form of flat breads and porridges (thick or thin) in Asia and Africa, and as animal feed in the Americas (http://www.icrisat.org/crop-sorghum.htm).…”

ABSTRACT. This study evaluated the chemical and genetic diversity of high-seed-yield sorghum germplasms from Korea, the United States, and South Africa. We identified significant differences in the chemical contents of whole plants at the heading stage in all cultivars, including differences in crude protein, fat, fiber, ash, neutral detergent fiber, acid detergent fiber, mineral, and fatty acid contents. Our results suggest that Banwoldang is the most appropriate cultivar for roughage because of its high protein yield. We identified significant differences in the tannin, flavonoid, amylose, mineral, crude fat, fatty acid, and 3-deoxyanthocyanin contents in the whole grain from all cultivars, but not in the mineral or crude fat contents. Tannin levels were generally low. IS645 contained the highest levels of flavonoids and linolenic acid compounds, and Moktak had the highest amylose and deoxyanthocyanidin content in the grain. To assess genetic diversity, we used 10 simple sequence repeat (SSR) primer sets to identify 38 2 J. Ryu et al. Genetics and Molecular Research 15 (3): gmr.15038677 alleles with 3-8 alleles per locus. Based on phylogenetic analysis of the SSR markers, the sorghum cultivars were divided into three major groups. Comparison of clusters based on chemical compositions with those based on SSRs showed that the groups formed by the three native Korean cultivars clustered similarly in molecular dendrograms. Association analysis was conducted for the 10 SSR marker; 48 chemical and growth traits were present for two marker traits (seed color and whole plant fatty acid content) with significant marker-trait associations. These markers could be used to select sorghum cultivars for breeding programs.

“…The RAPD marker requires no prior sequence information for the survey of plant genomes, but generally suffers from low resolution due to various issues associated with reproducibility, dominance and non-homologous DNA fragments, which are similar issues for other dominant markers (Koopman, 2005). However, successful RAPD applications assessing genetic diversity have been documented in many plants (Arif et al, 2010) such as sorghum (Iqbal et al, 2010), pomegranate (Ercisli et al, 2011) and sea buckthorn (Singh et al, 2006). Unfortunately, molecular markers have rarely been applied to assess genetic variation of Jerusalem artichoke (Dozet et al, 1993;Wangsomnuk et al, 2006;El Gengaihi et al, 2009).…”

ABSTRACT. Jerusalem artichoke (Helianthus tuberosus) is a wild relative of the cultivated sunflower (H. annuus); it is an old tuber crop that has recently received renewed interest. We used RAPD markers to characterize 147 Jerusalem artichoke accessions from nine countries. Thirty RAPD primers were screened; 13 of them detected 357 reproducible RAPD bands, of which 337 were polymorphic. Various diversity analyses revealed several different patterns of RAPD variation. More than 93% of the RAPD variation was found within accessions of a country. Weak genetic differentiation was observed between wild and cultivated accessions. Six groups were detected in this germplasm set. Four ancestral groups were found for the Canadian germplasm. The most genetically distinct accessions were identified. These findings provide useful diversity information for understanding the Jerusalem artichoke gene pool, for conserving ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 10 (4): 4012-4025 (2011) Genetic diversity in Helianthus tuberosus 4013Jerusalem artichoke germplasm, and for choosing germplasm for genetic improvement.
