Bolting and flowering control in sugar beet : relationships and effects of gibberellin, the bolting gene B and vernalization
Mutasa-Gottgens, Euphemia; Qi, Aiming; Zhang, Wenying; Schulze-Buxloh, Gretel; Jennings, Andrea; Hohmann, Uwe; Müller, Andreas E; Hedden, Peter (2010-09)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 ... -
Development of new quantitative physiological and molecular breeding parameters based on the sugar beet vernalization intensity model.
Chiurugwi, Tinashe; Holmes, Helen F.; Qi, Aiming; Chia, Tansy Y. P.; Hedden, Peter; Mutasa-Gottgens, Euphemia (2013-08)Sugar-beet crops, Beta vulgaris spp. vulgaris (L), suffer from premature bolting and flowering as a consequence of prolonged exposure to cold conditions (vernalization). This reduces crop yield and quality and could be ... -
Gibberellin as a factor in floral regulatory networks
Hedden, Peter; Mutasa-Gottgens, Euphemia (2009)Gibberellins (GAs) function not only to promote the growth of plant organs, but also to induce phase transitions during development. Their involvement in flower initiation in long-day (LD) and biennial plants is well ... -
Modification of gibberellin signalling (metabolism & signal transduction) in sugar beet: analysis of potential targets for crop improvement
Mutasa-Gottgens, Euphemia; Qi, Aiming; Thomas, Stephen; Mathews, Ann; Phillips, Andrew; Hedden, Peter (2009-04)Sugar beet, Beta vulgaris spp. vulgaris is a biennial long day plant with an obligate requirement for vernalization (prolonged exposure to low temperature). As a spring crop in temperate European climates, it is vulnerable ... -
A new RNASeq-based reference transcriptome for sugar beet and its application in transcriptome-scale analysis of vernalization and gibberellin responses
Mutasa-Gottgens, Euphemia; Joshi, Anagha; Holmes, Helen F.; Hedden, Peter; Gottgens, Berthold (2012)Sugar beet (Beta vulgaris sp. vulgaris) crops account for about 30% of world sugar. Sugar yield is compromised by reproductive growth hence crops must remain vegetative until harvest. Prolonged exposure to cold temperature ... -
Vernalization up-regulates gibberellin biosynthesis at the shoot apex prior to bolting in sugar beet
Holmes, Helen; Mutasa-Gottgens, Euphemia; Thomas, Stephen; Hedden, Peter (2010)
