Kohlrabi (Brassica oleracea var. gongylodes), with its edible stem tuber formed at the base of the plant stem, presents a valuable source of nutrients. The potential effects of plant growth regulators (PGRs), as well as various concentrations of different sugars on the in vitro development of kohlrabi were studied. Ten-day-old kohlrabi seedlings were cultivated in vitro for 5 weeks at 18?2?C on half-strength MS media containing different concentrations of carbon source such as sucrose, fructose, glucose, xylose and mannitol, combined with or without specific plant growth regulators (N6-benzyladenine (BA), gibberellic acid (GA3), 2,3,5-triiodobenzoic acid (TIBA)). Results showed no tuber formation in all treatments, but growth and development of treated kohlrabi seedlings was significantly affected in a distinctive manner, with a variety of morphological traits being altered in comparison to matching controls.

Influence of the photoperiod on growth, flowering, and seed development in vitro of Chenopodium rubrum L., a short day annual, was examined. Chenopodium rubrum plants modify their growth and reproductive development in accordance with the photoperiod. With an increase of day length, growth was stimulated, flowering was delayed, seed development occurred earlier, and the plants produced more seeds. By altering photoperiods during induction and evocation of flowering, it is shown that the photoperiod experienced by seedlings during early reproductive development determines the pattern of plant growth to the end of ontogenesis, the time to flowering, and the course of seed development. It is therefore concluded that growth and reproductive development of C. rubrum are photoperiod-sensitive to during a precise short part of its life cycle. .

SQUAMOSA-promoter binding protein-like (SPL) proteins are plant-specific transcript factors that play essential roles in plant growth and development. Although many SPL genes have been well characterized in model plants like Arabidopsis, rice and tomato, the functions of SPLs in strawberry are still largely elusive. In the present study, we cloned and characterized FvSPL10, the ortholog of AtSPL9, from woodland strawberry. Subcellular localization shows FvSPL10 localizes in the cell nucleus. The luciferase system assay indicates FvSPL10 is a transcriptional activator, and both in vitro and in vivo assays indicate FvSPL10 could bind to the promoter of FvAP1 and activate its expression. Ectopic expression of FvSPL10 in Arabidopsis promotes early flowering and increases organs size. These results demonstrate the multiple regulatory roles of FvSPL10 in plant growth and development and lay a foundation for investigating the biological functions of FvSPL10 in strawberry.

BAK1 (brassinosteroid-insensitive 1 (BRI1) associated receptor kinase 1) plays major roles in multiple signaling pathways as a coreceptor to regulate plant growth and development and stress response. However, the role of BAK1 in high light signaling is still poorly understood. Here we observed that overexpression of BAK1 in Arabidopsis interferes with the function of high light in promoting plant growth and development, which is independent of the brassinosteroid (BR) signaling pathway. Further investigation shows that high light enhances the phosphorylation of BAK1 and catalase activity, thereby reducing hydrogen peroxide (H2O2) accumulation. Catalase3 (CAT3) is identified as a BAK1-interacting protein by affinity purification and LC-MS/MS analysis. Biochemical analysis confirms that BAK1 interacts with and phosphorylates all three catalases (CAT1, CAT2, and CAT3) of the Arabidopsis genome, and the trans-phosphorylation sites of three catalases with BAK1-CD are identified by LC-MS/MS in vitro. Genetic analyses reveal that the BAK1 overexpression plants knocked out all the three CAT genes completely abolishing the effect of BAK1 on suppression of high light-promoted growth. This study first unravels the role of BAK1 in mediating high light-triggered activation of CATs, thereby degrading H2O2 and regulating plant growth and development in Arabidopsis.
