Abstract:
... The mechanical harvesting of corn has always been a problem for the development of the corn industry. In the present investigation, a tangential flow–transverse axial flow threshing test system was designed based on the 4YL-4/5 harvester. The structure design was modular, and the threshing drum and other key parts could be changed, or the technical parameters could be adjusted according to the nee ...

Abstract:
... Increasing the planting density of maize is an effective measure to improve its yield. However, plants under high planting density tend to trigger shade avoidance syndrome (SAS), reducing lodging resistance and ultimately yield drop. Phytochrome B (phyB) plays a dominant role in mediating shade avoidance response. This study constructed two hyperactive mutated alleles of maize PHYB1: ZmPHYB1Y⁹⁸F ( ...

Abstract:
... Certain traits of maize ears, such as kernels per ear, kernels per row, and rows per ear, are highly related with the grain yield and stress resistance. They can be used as quantitative indices for selecting superior varieties and analyzing experimental results in maize breeding. However, these traits are often manually obtained, which is laborious and prone to error. Image-based object counting m ...

However, very few EL QTLs have been cloned, and their molecular mechanisms are largely unknown. Here, using a genome wide association study (GWAS), we identified a QTL, YIGE1, which encodes an unknown protein that regulates EL by affe ...
