A promoter-swap strategy between the AtALMT and AtMATE genes increased Arabidopsis aluminium resistance and improved carbon-use efficiency for aluminium resistance
Liu J, Luo X, Shaff J, Liang C, Jia X, Li Z, Magalhães J and Kochian LV (2012). A promoter-swap strategy between the AtALMT and AtMATE genes increased Arabidopsis aluminium resistance and improved carbon-use efficiency for aluminium resistance. The Plant Journal 71(2):327–337. (DOI: 10.1111/j.1365-313X.2012.04994.x).
The primary mechanism of Arabidopsis aluminum (Al) resistance is based on root Al exclusion, resulting from Al-activated root exudation of the Al3+-chelating organic acids, malate and citrate. Root malate exudation is the major contributor to Arabidopsis Al resistance, and is conferred by expression of AtALMT1, which encodes the root malate transporter. Root citrate exudation plays a smaller but still significant role in Arabidopsis Al resistance, and is conferred by expression of AtMATE, which encodes the root citrate transporter. In this study, we demonstrate that levels of Al-activated root organic acid exudation are closely correlated with expression of the organic acid transporter genes AtALMT1 and AtMATE.

Approaches towards nitrogen- and phosphorus-efficient rice
Vinod KK, Heuer S (2012). Approaches towards nitrogen- and phosphorus-efficient rice. AoB PLANTS 2012: pls028; (DOI:10.1093/aobpla/pls028).
For thedevelopment of nutrient-efficient rice,a holistic approach should be followed combining optimized fertilizer management with enhanced nutrient uptake via a vigorous root system, leading to increased grain filling and yield. Despite an increasing number of N- and P-related genes and QTLs being reported, very feware actively used inmolecular breeding programmes. The complex regulation of N- and P-related pathways challenges breeders and the research community to identify large-effect genes/QTLs. For this it will be important to focus more on the analysis of tolerant genotypes rather than model plants, since tolerance pathways may employ a different set of genes.

A reference microsatellite kit to assess for genetic diversity of Sorghum bicolor (Poaceae)
Billot C, Rivallan R, Sall MN, Fonceka D, Deu M, Glaszmann J-C, Noyer J-L, Rami J-F, Risterucci A-M, Wincker P, Ramu P and Hash CT (2012). A reference microsatellite kit to assess for genetic diversity of Sorghum bicolor (Poaceae). American Journal of Botany 99(6):e245–e250. (DOI: 10.3732/ajb.1100548).
Discrepancies in terms of genotyping data are frequently observed when comparing simple sequence repeat (SSR) data sets across genotyping technologies and laboratories. This technical concern introduces biases that hamper any synthetic studies or comparison of genetic diversity between collections. To prevent this for Sorghum bicolor, we developed a control kit of 48 SSR markers.

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.
