Transcript levels of VRN1, PPD-D1, PPD-B1 and PPD-A1 genes during different developmental stages of winter wheat

Popis výsledku v původním jazyce

The phenology of winter wheat is largely affected by the expression of the vernalization gene VRN1 and the PPD-D1, PPD-B1 and PPD-A1 genes responsible for sensitivity to photoperiod. The transcript levels of these genes were studied in six winter and one facultative wheat variety during growing season 2020. During the development of the shoot apex, the activity of VRN1 and PPD-D1 is gradually increased, although some transcript level of the VRN1 gene was found also in the leaves during the cold weather. In the spring, after vernalization fulfilment and during prolonged daylight, the increased expression of VRN1 and PPD-D1 was related to the change of the developmental stage. From a certain developmental stage, an increase in expression was observed, which corresponds to a change in development. However, the activity of the PPD-B1 decreases when the development of the shoot apex increases. It is possible that certain combinations of PPD1 loci alleles can alter head timing by acceleration which can protect sensitive floral meristem during unfavourable weather conditions and therefore, the information about allele combination and regulation conditions of these genes can be used for breeding of new varieties suitable for specific environmental conditions.
