1. Dynamic gene amplification and function diversification of grass-specific O-methyltransferase gene family

Author:

Subject:
S-adenosylmethionine; benzoxazinoids; biosynthesis; gene amplification; gene expression; genes; grasses; insect resistance; methyltransferases; phylogeny; roots; secondary metabolites; suberin
Abstract:
... The plant O-methyltransferases are dependent on S-Adenosyl-l-methionine, which can catalyze a variety of secondary metabolites. Here we identified different number of OMT genes from the respective grass genomes. Phylogenetic analysis showed that this OMT gene family is a grass-specific gene family that is different from COMT. Most of genes were expanded by tandem and segment duplication after the ...

Abstract:
... Wall‐associated kinases (WAKs) have recently been identified as major components of fungal and bacterial disease resistance in several cereal crop species. However, the molecular mechanisms of WAK‐mediated resistance remain largely unknown. Here, we investigated the function of the maize gene ZmWAK‐RLK1 (Htn1) that confers quantitative resistance to northern corn leaf blight (NCLB) caused by the h ...

Subject:
aluminum; benzoxazinoids; biosynthesis; chelation; corn; cultivars; exudation; hydroxamic acids; root growth; root tips; salicylic acid
Abstract:
... BACKGROUND AND AIMS: Although aluminum (Al) exclusion via root exudation of organic matters is a common resistance mechanism adopted by many plant species, whether root exudation of benzoxazinoids, such as hydroxamic acids (HAs), confers Al resistance remains unclear. METHODS: We performed physiological characterization for an Al-resistant maize cultivar TY and a sensitive maize cultivar ZD. RESUL ...
