Overexpression of Taetr1-1 promotes enhanced seed dormancy and ethylene insensitivity in wheat.

Taetr1-1 can promote enhanced seed dormancy and ethylene insensitivity in wheat, indicating a conserved function of ETR1 in regulating seed dormancy. Lots of wheat cultivars have weak dormant seed. Weak seed dormancy can cause pre-harvest sprouting (PHS) in grain which significantly reduces grain yield and quality.

Genome-wide association study reveals a NAC transcription factor TaNAC074 linked to pre-harvest sprouting tolerance in wheat.

Twelve QTL associated with pre-harvest sprouting tolerance were identified using association analysis in wheat. Two markers were validated and a candidate gene TaNAC074 for Qgpf.cas-3B.

Combining QTL mapping and gene co-expression network analysis for prediction of candidate genes and molecular network related to yield in wheat.

Background: Wheat (Triticum aestivum L.) is an important cereal crop. Increasing grain yield for wheat is always a priority.
