Flowering time is an important agronomic trait, and wide variation exists among Brassica rapa. In Arabidopsis, FLOWERING LOCUS C (FLC) plays an important role in modulating flowering time and the response to vernalization. Brassica rapa contains several paralogues of FLC at syntenic regions. BrFLC2 maps under a major flowering time and vernalization response quantitative trait locus (QTL) at th...
Timing of flowering is key to the reproductive success of many plants. In temperate climates, flowering is often coordinated with seasonal environmental cues such as temperature and photoperiod. Vernalization, the process by which a prolonged exposure to the cold of winter results in competence to flower during the following spring, is an example of the influence of temperature on the timing of...
Pak choi is a seed vernalization-type plant whose vernalization mechanism is currently unclear. Therefore, it is critical to discover genes related to vernalization and research its functions during vernalization in pak choi. Here, the gene expression profiles in the shoot apex were analyzed after low temperature treatment using high-throughput RNA sequencing technology. The results showed that...
Steep environmental gradients provide ideal settings for studies of potentially adaptive phenotypic and genetic variation in plants. The accurate timing of flowering is crucial for reproductive success and is regulated by several pathways, including the vernalization pathway. Among the numerous genes known to enable flowering in response to vernalization, the most prominent is FLOWERING LOCUS C...
Vernalization, the cold-induced acceleration of flowering, involves the epigenetic silencing of the floral repressor gene FLOWERING LOCUS C (FLC). We investigated the molecular basis for variation in vernalization in Arabidopsis natural accessions adapted to different climates. A major variable was the degree to which different periods of cold caused stable FLC silencing. In accessions requirin...
Vernalization is the acceleration of flowering by prolonged cold that aligns the onset of reproductive development with spring conditions. A key step of vernalization in Arabidopsis is the epigenetic silencing of FLOWERING LOCUS C (FLC), which encodes a repressor of flowering. The vernalization-induced epigenetic silencing of FLC is associated with histone deacetylation and H3K27me2 and H3K9me2...
Rapeseed has formed three ecological types, namely winter, semi-winter, and spring during the long domestication process. Different ecotypes have different low-temperature requirements for floral initiation. growth a large demand nitrogen, amount of nitrogen application significantly impacts number flowering. Meanwhile, time imitation determined quantity bud, final pods, yield rapeseed. Therefo...
BACKGROUND AND AIMS Accurately representing development is essential for applying crop simulations to investigate the effects of climate, genotypes or crop management. Development in wheat (Triticum aestivum, T. durum) is primarily driven by temperature, but affected by vernalization and photoperiod, and is often simulated by reducing thermal-time accumulation using vernalization or photoperiod...

In many temperate plant species, prolonged cold treatment, known as vernalization, is one of the most critical steps in the transition from the vegetative to the reproductive stage. In contrast to recent advances in understanding the molecular basis of vernalization in Arabidopsis non-vernalization mutants or the spring growth habits of cereal crops such as wheat and barley, natural variations ...
