Effect of VRN1 and PPD1 genes on anthesis date and wheat growth

Crop & Pasture Science, 2017
Phasic development of wheat is largely determined by the interaction of the VRN1 and PPD1 genes with vernalising temperature and photoperiod. VRN1 and PPD1 are regulatory genes, known to influence freezing tolerance, plant morphology and grain yield as

Epigenomic identification of vernalization cis-regulatory elements in winter wheat [PDF]

Genome Biology
Background Winter wheat undergoes vernalization, a process activated by prolonged exposure to low temperatures. During this phase, flowering signals are generated and transported to the apical meristems, stimulating the transition to the inflorescence ...

Post-Translational Control of TaFT1 by WAPO1 Ubiquitination Shapes Spike Architecture and Yield in Wheat. [PDF]

Plant Biotechnol J
ABSTRACT The florigen protein TaFT1 coordinately regulates heading time and spikelet number per spike (SNS), serving as a key yield determinant in wheat. However, how its stability is post‐translationally controlled in the shoot apical meristem remains unclear.

Chromatin loops gather targets of upstream regulators together for efficient gene transcription regulation during vernalization in wheat [PDF]

Genome Biology
Background Plants respond to environmental stimuli by altering gene transcription that is highly related with chromatin status, including histone modification, chromatin accessibility, and three-dimensional chromatin interaction.

Genomic and Physiological Insights Into Heat-Drought Tolerance in Wheat Through GWAS and Phenotypic Evaluation. [PDF]

Plant Cell Environ
ABSTRACT Climate change‐driven heat and drought stresses during reproductive stages significantly threaten wheat productivity. To investigate the genetic and physiological basis of combined heat–drought (HD) tolerance, we evaluated 345 wheat genotypes under three environments of HD stresses, non‐stress glasshouse conditions and a late‐sowing field ...

VERNALIZATION2 alters early tiller development in a facultative spring hexaploid bread wheat. [PDF]

New Phytol
Summary An extended period of cold exposure enables the process of vernalization in winter cereals and is important for the synchronised timing of the floral transition. The cereal‐specific floral repressor VERNALIZATION2 (VRN2) has an integral role in vernalization, yet this locus remains poorly characterised in facultative spring hexaploid wheat ...

MicroRNA156 and its targeted SPL genes interact with the photoperiod, vernalization, and gibberellin pathways to regulate wheat heading time. [PDF]

Plant J
SUMMARY Heading time has a large impact on adaptation to different environments and crop productivity. In this study, we characterized the effect of the endogenous age pathway on heading time and its interactions with the photoperiod and vernalization pathways in the leaves of tetraploid wheat (Triticum turgidum ssp. durum).

Molecular-physiological model integration revolutionizes cereal flowering prediction. [PDF]

New Phytol
Summary Rapid prediction and control of flowering time is essential for breeding crops resilient to changing climates. Current models often fail to predict flowering time in new cultivars because molecular models lack integration of environmental signals, while physiological models inadequately capture the interactions of vernalization, photoperiod and

Long-Amplicon Single-Molecule Sequencing Reveals Novel, Trait-Associated Variants of VERNALIZATION1 Homoeologs in Hexaploid Wheat

Frontiers in Plant Science, 2022
The gene VERNALIZATION1 (VRN1) is a key controller of vernalization requirement in wheat. The genome of hexaploid wheat (Triticum aestivum) harbors three homoeologous VRN1 loci on chromosomes 5A, 5B, and 5D.
