Adaptive diversification through structural variation in barley

This study presents a barley pangenome revealing structural variation linked to traits like disease resistance and plant architecture, highlighting its role in adaptive evolution.

Anatomical insights into the vascular lay-out of the barley rachis: implications for transport and spikelet connection

This study examines the vascular anatomy of barley rachis to understand its relationship with spike size and transport capacity.

Dosage of duplicated and antifunctionalized homeobox proteins influences spikelet development in barley

This study shows that the dosage of HvHOX1 and HvHOX2, two antagonistic homeobox transcription factors, influences spikelet development in barley.

The barley mutant multiflorus2.b reveals quantitative genetic variation for new spikelet architecture

This study identifies QTLs for spikelet determinacy and supernumerary spikelet phenotypes in the barley mutant multiflorus2.b, revealing polygenic inheritance.

Strategies of grain number determination differentiate barley row-types

This study identifies differences in grain number determination mechanisms between two-rowed and six-rowed barley types by analyzing yield components and their interactions under greenhouse and field conditions.

COMPOSITUM 1 (COM1) contributes to the architectural simplification of barley inflorescence via meristem identity signals

This study identifies COM1 as a gene regulating inflorescence shape in barley by controlling meristem identity signals, with implications for evolution and breeding.
