Seleção de linhagens de sorgo granífero eficientes e responsivas à aplicação de fósforo (Selection of grain sorghum lines efficient and responsive to phosphorus application)
Rodrigues F, Magalhães JV, Guimarães CT, Tardin FD and Schaffert RE (2014). Seleção de linhagens de sorgo granífero eficientes e responsivas à aplicação de fósforo (Selection of grain sorghum lines efficient and responsive to phosphorus application). Pesquisa Agropecuária Brasileira 49(8):613–621 (DOI: 10.1590/S0100-204X2014000800005). Article in Portuguese with abstract in English. (G7010.03.06)
Abstract: The objective of this work was to select sorghum lines simultaneously responsive to phosphorus fertilization and with high productive efficiency regarding this nutrient. Thirty six sorghum inbred lines were evaluated in a randomized complete block design, with two replicates. The traits used to evaluate the productive efficiency were average yield and efficiencies of absorption, utilization, and use of phosphorus, with and without phosphorus fertilization. For the analysis of the responsivity to the nutrient, the evaluated traits were relative yield and apparent recovery, physiological, and agronomic efficiencies. The lines were genetically divergent as to the efficiencies of absorption, utilization, and use of phosphorus, and to the responsivity to the nutrient, suggesting the possibility of producing hybrids destined to different market niches. The most responsive lines were P9401, BR007B, BR008B, SC414-12E, and SC566, and the most efficient ones under low phosphorus availability were ATF40B, SC566, BR005R, CMSXS225, and BR012 (R6). The ATF40B, ATF54 (f61), ATF54 (f596), QL3, and SC566 lines showed better simultaneous performance for the different evaluated efficiencies and for the responsivity to phosphorus. The evaluation of productivity alone, under different phosphorus availabilities, already makes it possible to identify efficient and responsive lines to phosphorus.

Selection of sorghum hybrids grown under aluminum saturation
Menezes CB, Carvalho Junior GA, Silva LA, Bernardino KC, Magalhães JV, Guimarães CT, Guimarães LJM and Schaffert RE (2014). Selection of sorghum hybrids grown under aluminum saturation. Genetics and Molecular Research 13(3):5964–5973 (DOI: 10.4238/2014.August.7.12).
Abstract: The purpose of this study was to evaluate 165 hybrids derived from lines previously selected for aluminum (Al) tolerance. Nine check cultivars were used, eight commercial hybrids and one experimental hybrid. Hybrids were evaluated at three levels of Al saturation (0, 20 and 40% on average). The differences between the environments were significant. Environment with 0% Al saturation yielded 29.5% more than that with 40% Al saturation, showing the importance of genotype selection for acid soils. The best check cultivar was the hybrid DKB550. The hybrids AG1020 and AG1040 also performed well, where the latter was more tolerant but the former more responsive to environment improvement. The hybrid BRS304 was susceptible to high levels of Al saturation. The three commercial BRS hybrids (BRS310, BRS330 and BRS332) performed better than BRS304 at high Al saturation. The hybrid BRS330 was the best BRS hybrid to grow on a field with high Al saturation. The hybrid DKB559 performed well at high Al saturation but did not respond to environment improvement. The hybrids 727029, 727039, 729041, 729095, 729109, AG1040, and DKB550 were tolerant to higher levels of Al saturation and responsive to environment improvement, and showed good stability and adaptability at both low and high Al saturation.

Structural variations in plant genomes
Saxena RK, Edwards D and Varshney RK (2014). Structural variations in plant genomes. Briefings in Functional Genomics 13(4):296-307 (DOI: 10.1093/bfgp/elu016).
Abstract: Differences between plant genomes range from single nucleotide polymorphisms to large-scale duplications, deletions and rearrangements. The large polymorphisms are termed structural variants (SVs). SVs have received significant attention in human genetics and were found to be responsible for various chronic diseases. However, little effort has been directed towards understanding the role of SVs in plants. Many recent advances in plant genetics have resulted from improvements in high-resolution technologies for measuring SVs, including microarray-based techniques, and more recently, high-throughput DNA sequencing. In this review we describe recent reports of SV in plants and describe the genomic technologies currently used to measure these SVs.
