Nicotianamine (NA) is an important divalent metal chelator and the main precursor of phytosiderophores. NA is synthesized from S-adenosylmethionine in a process catalyzed by nicotianamine synthase (NAS). In this study, a set of structural and phylogenetic analyses have been applied to identify the maize NAS genes based on the maize genome sequence release.(More)
Plant annexins are Ca2+- and phospholipid-binding proteins forming an evolutionary conserved multi-gene family. They are implicated in the regulation of plant growth, development, and stress responses. With the availability of the maize genome sequence information, we identified 12 members of the maize annexin genes. Analysis of protein sequence and gene(More)
Maize is a cereal crop that is grown widely throughout the world in a range of agro-ecological environments. Trehalose is a nonreducing disaccharide of glucose that has been associated with tolerance to different stress conditions, including salt and drought. Bioinformatic analysis of genes involved in trehalose biosynthesis and degradation in maize has not(More)
Maize (Zea mays ssp. mays L.) is an important model organism for fundamental research in the agro-biotechnology field. Aldehydes were generated in response to a suite of environmental stresses that perturb metabolism including salinity, dehydration, desiccation, and cold and heat shock. Many biologically important aldehydes are metabolized by the(More)
The genetic diversity of four new species related to southwestern Sichuan buckwheats was examined using karyotypes, allozymes and intersimple sequence repeats (ISSR). Karyotype analysis showed that Fagopyrum wenchuanense, F. qiangcai and F. pugense are diploid (2n = 2x = 16) while F. crispatofolium is tetraploid (2n = 4x = 32). The karyotype evolutionary(More)
