TAILIEUCHUNG - An APETALA1 ortholog affects plant architecture and seed yield component in oilseed rape (Brassica napus L.)

Increasing the productivity of rapeseed as one of the widely cultivated oil crops in the world is of upmost importance.

As flowering time and plant architecture play a key role in the regulation of rapeseed yield lt br gt understanding the genetic mechanism underlying these traits can boost the rapeseed breeding. Meristem identity lt br gt genes are known to have pleiotropic effects on plant architecture and seed yield in various crops. To understand lt br gt the function of one of the meristem identity genes APETALA1 AP1 in rapeseed we performed phenotypic analysis lt br gt of TILLING mutants under greenhouse conditions. Three stop codon mutant families carrying a mutation in Bna. lt br gt paralog were analyzed for different plant architecture and seed yield-related traits. lt br gt Results It was evident that stop codon mutation in the K domain of paralog caused significant lt br gt changes in flower morphology as well as plant architecture related traits like plant height branch height and lt br gt branch number. Furthermore yield-related traits like seed yield per plant and number of seeds per plants were also lt br gt significantly altered in the same mutant family. Apart from .
