Vernalization regulatory network identifies potential novel functions for genes in the HvVRN2 locus

Introduction The transition to flowering is a major physiological event in plants. Its timing has a large agronomic impact on cereal crops of the Pooideae family (Carrera et al., 2024). This process is highly controlled by environmental conditions and both gene diversity and regulation. Vernalization is the induction of flowering after exposure to a prolonged cold period.

Vernalization regulatory network identifies potential novel functions for ZCCT genes within HvVRN2

Abstract Flowering is a key yield determinant, controlled by environmental and genetic factors. Vernalization requirement, a prolonged cold period to promote flowering, is determined in barley (Hordeum vulgare L.) by the allele in HvVRN1 and the presence of locus HvVRN2, which consists of two ZCCT genes: HvVRN2a and HvVRN2b. While the effect of HvVRN2 presence is well-known, its outcome on the transcriptome and other genes outside the flowering/vernalization pathway remains unknown.
