Bolting and flowering control in sugar beet: relationships and effects of gibberellin, the bolting gene B and vernalization
BACKGROUND AND AIMS Bolting, the first visible sign of reproductive transition in beets (Beta vulgaris), is controlled by the dominant bolting gene B (B allele), which allows for flowering under long days (LDs, >14 h light) without prior vernalization. The B-locus carries recessive alleles (bb) in sugar beet (Beta vulgaris L. spp. vulgaris), so that vernalization and LDs are required for boltin...
متن کاملEpigenomics and bolting tolerance in sugar beet genotypes.
In sugar beet (Beta vulgaris altissima), bolting tolerance is an essential agronomic trait reflecting the bolting response of genotypes after vernalization. Genes involved in induction of sugar beet bolting have now been identified, and evidence suggests that epigenetic factors are involved in their control. Indeed, the time course and amplitude of DNA methylation variations in the shoot apical...
متن کاملComparison of Promoter Sequences of Flowering Control Genes, FT1 and Three Versions of VIN3, in Susceptible and Resistant Sugar Beet Genotypes to Bolting
Autumn sowing of sugar beet is a suitable way in sustainable agriculture. Bolting is an undesirable phenomenon which reduces sugar beet yield and it is the most important limiting factor in autumn sowing of sugar beet. Identification and comparison of the sequence of flowering genes in various genotypes can help to understand the molecular mechanisms controlling bolting. In the previous studies...
متن کاملInteractions between Vernalization and Photoperiod on the Flowering and Bolting of Different Turnip Varieties
The interactions between vernalization and photoperiodic effects on the flowering of 12 turnip varieties were examined under controlled environment. Seedlings of all varieties bolted and flowered under a long-day condition of 24 h day-length (LD) when the germinated seeds had been pre-exposed to low temperature at 3 •Ž (LT) for 30 days. Under the LD condition, the ratio of flower formation of a...
متن کاملresponse of sugar beet (beta vulgaris l.) to photoperiod before and after bolting and flowering
this research was carried at the university of reading in 1999. the aim was to estimate the effects of 18 hd-1 (long-day, ld) and 12 hd-1 (short-day, sd) light exposure duration of plants before bolting or flowering on time to bolt and flower in two bolting susceptible (bsg, ic1) and bolting resistant (brg, saxon) genotypes of sugar beet. so, two experiments were conducted. the experiments were...
