Exogenous Gibberellins Induce Wheat Spike Development under Short Days Only in the Presence of VERNALIZATION1

Pearce, Stephen; Vanzetti, Leonardo Sebastian; Dubcovsky, Jorge (2013-11)

The activation of the meristem identity gene VERNALIZATION1 (VRN1) is a critical regulatory point in wheat (Triticum spp.) flowering. In photoperiod-sensitive wheat varieties, VRN1 is expressed only under long days (LDs), ...
Fine mapping and epistatic interactions of the vernalization gene VRN-D4 in hexaploid wheat

Kippes, Néstor Fabián; Zhu, Jie; Chen, Andrew; Vanzetti, Leonardo Sebastian; Lukaszewski, Adam; Nishida, Hidetaka; Kato, Kenji; Dvorak, Jan; Dubcovsky, Jorge (2014-02)

Wheat vernalization requirement is mainly controlled by the VRN1, VRN2, VRN3, and VRN4 genes. The first three have been cloned and have homoeologs in all three genomes. VRN4 has been found only in the D genome (VRN-D4) and ...
Identification and characterization of Rht25, a locus on chromosome arm 6AS affecting wheat plant height, heading time, and spike development

Youngjun Mo; Vanzetti, Leonardo Sebastian; Hale, Iago; Spagnolo, Emiliano J.; Guidobaldi, Fabio; Al-Oboudi, Jassim; Odle, Natalie; Pearce, Stephen; Helguera, Marcelo; Dubcovsky, Jorge (2018)

Understanding genes regulating wheat plant height is important to optimize harvest index and maximize grain yield. In modern wheat varieties grown under high-input conditions, the gibberellin-insensitive semi-dwarfing ...
