The nucleotide-binding site (NBS)-leucine-rich repeat (LRR) gene family comprises the largest number of known disease resistance (R) genes and is one of the largest gene families in plants. In the present study, the full-length cDNA of ZmNL (GenBank Accession Number KF765443) was isolated using Rapid Amplification of cDNA Ends. The nucleotide sequence of ZmNL contains an open reading frame of 3156 bp...
Understanding the combining ability and heterosis of available germplasm is a prerequisite for successful maize improvement and breeding. The objectives of this study were to analyze the combining ability and heterosis of seven representative maize germplasm populations, and further, to evaluate their potential utility in germplasm improvement. A total of 21 crosses were made among these seven populations...
Salinity is an adverse environmental stress that limits the yield and quality of maize. As one of the most important osmolytes present in higher plants, glycinebetaine helps stabilize metabolism in plant cells and protects the constituents of cells from damage. In this study, a gene from Atriplex micrantha that encodes betaine aldehyde dehydrogenase was introduced by Agrobacterium-mediated transformation...
Head smut is a disease caused severely yield losses both in commercial maize and seed production in the spring maize growing region in northeastern China. In previous study, we located the major QTL qHS2.09 between SNP PZE-102187486 and PZE-102188421 by combined linkage and association mapping within an interval of ≈1.00 Mb. In this study, we report the development of six derived cleaved amplified...
Grain moisture in maize at harvest depends on the grain drying rate (GDR) after physiological maturity. The maize plants with high GDR can reduce grain moisture rapidly, which will shorten the drying time after harvest and prevent the grain to be mildew and enhance maize quality. In this study, A total of 280 recombinant inbred lines that were derived from a cross between Ji846 (high drying rate,...
