- ... 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 ...

- ... BACKGROUND: Insect herbivory poses a major threat to maize. Benzoxazinoids are important anti-insect secondary metabolites in maize, whose biosynthetic pathway has been extensively studied. However, yet little is known about how benzoxazinoids are regulated in maize, partly due to lack of mutant resources and recalcitrance to genetic transformation. Transient systems based on mesophyll- or culture ...

- ... 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 ...
