Genetic diversity in Iranian chickpea (Cicer arietinum L.) landraces as revealed by microsatellite markers
Naghavi MR, Monfared SR and Gomez H (2012). Genetic diversity in Iranian chickpea (Cicer arietinum L.) landraces as revealed by microsatellite markers. Czech Journal of Genetics and Plant Breeding 48(3):131–138.
Abstract: To estimate the genetic diversity of chickpea germplasm from Iran, a total of 307 landraces from 4 regions including: northern areas (29 from Ardebil, 3 from Qazvin and 5 from Mazanderan provinces), temperate (16 from Kermanshah, 2 from Semnan, 54 from Khorasan and 20 from Kerman provinces), semi-arid (28 from Ghom and 56 from Isfahan provinces) and cold areas (15 from West Azarbayjan, 52 from Tehran and 27 from East Azarbayjan provinces) were analysed using 16 microsatellite loci. The number of alleles per microsatellite locus ranged from 8 to 29, with an average of 19.31 per locus. A high level of genetic diversity in the northern area (He = 0.76), even with a limited number of available landraces (37) compared with the other three regions (84–94), might confirm the northern Persia as part of the chickpea centre of origin. The neighbour-joining tree showed a low relationship between molecular divergence and the geographical grouping of chickpea. Moreover, cluster analyses based on molecular data showed that the northern area was separated clearly from the other three regions, indicating a physical barrier or geographical and environmental differences among these regions. A wide genetic diversity of Iranian chickpea landraces is a critical component for future selection and use of this germplasm for future breeding of chickpea.

Genetic and physical mapping of candidate genes for resistance to Fusarium oxysporum f.sp. tracheiphilum Race 3 in cowpea [Vigna unguiculata (L.) Walp]
Pottorff M, Wanamaker S, Ma YQ, Ehlers JD, Roberts PA, Close TJ (2012). Genetic and physical mapping of candidate genes for resistance to Fusarium oxysporum f.sp. tracheiphilum Race 3 in cowpea [Vigna unguiculata (L.) Walp]. PLoS ONE 7(7):e41600. (DOI: 10.1371/journal.pone.0041600). (G6010.02/G7010.07.01).
Fusarium oxysporum f.sp. tracheiphilum (Fot) is a soil-borne fungal pathogen that causes vascular wilt disease in cowpea. Fot race 3 is one of the major pathogens affecting cowpea production in California. Identification of Fot race 3 resistance determinants will expedite delivery of improved cultivars by replacing time-consuming phenotypic screening with selection based on perfect markers, thereby generating successful cultivars in a shorter time period. Resistance to Fot race 3 was studied in the RIL population California Blackeye 27 (resistant) x 24-125B-1 (susceptible). Biparental mapping identified a Fot race 3 resistance locus, Fot3-1, which spanned 3.56 cM on linkage group one of the CB27 x 24-125B-1 genetic map.

Genetic and molecular mechanisms of aluminum tolerance in plants
Simões CC; Melo JO; Magalhaes JV; Guimarães CT (2012). Genetic and molecular mechanisms of aluminum tolerance in plants. Genetics and Molecular Research 11 (3):1949–1957. (DOI: 10.4238/2012.July.19.14). http://geneticsmr.com/articles/1770. (G7010.03.02).
Genes encoding membrane transporters and accessory transcription factors, as well as cis-elements that enhance gene expression are involved in Al tolerance in plants, thus studies of these genes and accessory factors should be the focus of molecular breeding efforts aimed at improving Al tolerance in crops. In this review, we describe the main genetic and molecular studies that led to the identification and cloning of genes associated with Al tolerance in plants. We include recent findings on the regulation of genes associated with Al tolerance. Understanding the genetic, molecular, and physiological aspects of Al tolerance in plants is important for generating cultivars adapted to acid soils, thereby contributing to food security worldwide.

Gene expression profile of wheat seedling response to drought stress by cDNA-AFLP
Zhang Y, Li J, Wang Z, Fan Z, Wang H, Zhang H (2012). Gene expression profile of wheat seedling response to drought stress by cDNA-AFLP. Journal of Triticeae Crops 32(2):240–244. (G7010.02.01). Article in Chinese with abstract in English. Not open access: view online
Drought is one of the most adverse environmental factors affecting wheat yield and quality. Under drought stress, target genes in wheat could be activated and expressed to produce drought-induced proteins, enabling plants to actively adapt to drought, and to maintain survival and yield formation. So, studying on drought-induced proteins and the related genes is essential for future genetic engineering and crop breeding of drought-resisting and water-saving. The objective of this research is to analyse the gene expression profile of wheat under drought stress, and to detect the fragments related to drought-resistant gene expression. Genes induced by drought stress in the seedling of Xinjiang spring wheat cultivar Xinchun 6 at 2-leaf stage were analysed by cDNA-AFLP techniques.
