Research Plan
Progress of on-going collaboration
Mapping based cloning and functional analysis of grain length QTL GL3.1
GL3.1
Cloning of GL3.1
Overexpress GL3.1-WY3 increase the grain length
GL3.1 is predicted to encode a Ser/Thr
phosphatase with kelch domain
GL3.1 increase the grain length, weight and yield
The plot grain yield was significantly increased in NIL (+11.1%)
Subcellular location of GL3.1
GL3.1 in both parents was detected throughout the entire cell
Subcellular location of Cyclin-T1;3
When GL3.1 was co-expressed with Cyclin-T1;3, increased accumulation of GL3.1 was observed in the nuclei
