Contemplation on wheat vernalization

Frontiers in Plant Science, 2023
Vernalization is a period of low non-freezing temperatures, which provides the competence to flower. This mechanism ensures that plants sown before winter develop reproductive organs in more favourable conditions during spring.

MiR172-APETALA2-like genes integrate vernalization and plant age to control flowering time in wheat.

PLoS Genetics, 2022
Plants possess regulatory mechanisms that allow them to flower under conditions that maximize reproductive success. Selection of natural variants affecting those mechanisms has been critical in agriculture to modulate the flowering response of crops to ...

Heading Date QTL in Winter Wheat (Triticum aestivum L.) Coincide with Major Developmental Genes VERNALIZATION1 and PHOTOPERIOD1. [PDF]

PLoS ONE, 2016
In wheat (Triticum aestivum L.), time from planting to spike emergence is influenced by genes controlling vernalization requirement and photoperiod response.

Wild emmer wheat, the progenitor of modern bread wheat, exhibits great diversity in the VERNALIZATION1 gene

Frontiers in Plant Science, 2023
Wild emmer wheat is an excellent reservoir of genetic variability that can be utilized to improve cultivated wheat to address the challenges of the expanding world population and climate change. Bearing this in mind, we have collected a panel of 263 wild

Evolution of VRN-1 homoeologous loci in allopolyploids of Triticum and their diploid precursors

BMC Plant Biology, 2017
Background The key gene in genetic system controlling the duration of the vegetative period in cereals is the VRN1 gene, whose product under the influence of low temperature (vernalization) promotes the transition of the apical meristem cells into a ...

Genome–wide association mapping for heading date in oats under subtropical environments

Scientia Agricola, 2021
: Selection for heading date has been a decisive factor to increase areas cropped with oats in Brazil. Although important to oat breeders, genomic regions controlling heading date have not been completely identified.

Transcriptome analysis of the vernalization response in barley (Hordeum vulgare) seedlings. [PDF]

PLoS ONE, 2011
Temperate cereals, such as wheat (Triticum spp.) and barley (Hordeum vulgare), respond to prolonged cold by becoming more tolerant of freezing (cold acclimation) and by becoming competent to flower (vernalization).

Transcriptome profiling of developing leaf and shoot apices to reveal the molecular mechanism and co-expression genes responsible for the wheat heading date

BMC Genomics, 2021
Background Wheat is one of the most widely planted crops worldwide. The heading date is important for wheat environmental adaptability, as it not only controls flowering time but also determines the yield component in terms of grain number per spike ...

Natural Variation of TaSG-D1-TaWRKY53 Module Regulates Heading Date in Wheat. [PDF]

Plant Biotechnol J
ABSTRACT Heading date is a critical determinant of regional adaptation and yield potential. Here, we identify an E286K substitution in TaSG‐D1, encoding an STKc_GSK3 kinase, which delays heading date in wheat. Mechanistically, this substitution strengthens the physical interaction between TaSG‐D1 and TaWRKY53 and enhances the phosphorylation of ...
