Abstract:
... Crop yield is of a quantitative nature. Two complementary approaches linkage mapping and genome-wide association study (GWAS) have been employed for the identification of loci influencing maize yield. In previous research, we meta-analyzed QTL for maize yield. Here, we tried to integrate meta-QTL and GWAS analyses to dissect candidate genes for maize yield. A total of seven candidate genes were de ...

Abstract:
... Fusarium verticillioides is a fungal pathogen that is responsible for maize ear rot and stalk rot diseases worldwide. The fungus also produces carcinogenic mycotoxins, fumonisins on infested maize. Unfortunately, we still lack clear understanding of how the pathogen responds to host and environmental stimuli to trigger fumonisin biosynthesis. The heterotrimeric G protein complex, consisting of can ...

Abstract:
... Maize (Zea mays L.) is a monoecious grass plant in which mature male and female florets form the tassel and ear, respectively. Maize is often used as a model plant to study flower development. Several maize tassel seed mutants, such as the recessive mutants tasselseed1 (ts1) and tasselseed2 (ts2), exhibit a reversal in sex determination, which leads to the generation of seeds in tassels. The pheno ...
