Special Issue Information

Dear Colleagues,

This Special Issue, titled “Plant Development and Hormonal Signaling”, in the International Journal of Molecular Sciences is a commendable initiative. Well-known plant hormones (phytohormones) include Abscisic acid; Auxins; Brassinosteroids; Cytokinins; Ethylene; Gibberellins; Salicylic acid; and Strigolactones. Some small peptide hormones, Polyamines, Nitric oxide (NO), Triacontanol, and other molecules are also involved in intercellular signaling, regulating plant growth and development and the defense mechanism of plant cells. Therefore, hormone signaling plays an important role in a plant’s whole life, including the formation of organs, flowering, fruiting, biotic and abiotic stress, etc. We encourage researchers to contribute papers focused on the topics of interest for this Special Issue, including, but not limited to, plant hormones, interactions between hormones, and hormone regulation in plant development. Original research articles and full reviews, communications, and other article types are welcome.

The diversity in the petal morphology of chrysanthemums makes this species an excellent model for investigating the regulation mechanisms of petal size. However, our understanding of the molecular regulation of petal growth in chrysanthemums remains limited. The GASA (gibberellic acid [GA]-stimulated Arabidopsis) protein plays a significant role in various aspects of plant growth and development. Previous studies have indicated that GEG (a gerbera homolog of the gibberellin-stimulated transcript 1 [GAST1] from tomato) is involved in regulating ray petal growth by inhibiting cell expansion in gerberas. In this study, we successfully cloned the GASA family gene from chrysanthemums, naming it CmGEG, which shares 81.4% homology with GEG. Our spatiotemporal expression analysis revealed that CmGEG is expressed in all tissues, with the highest expression levels observed in the ray florets, particularly during the later stages of development. Through transformation experiments, we demonstrated that CmGEG inhibits petal elongation in chrysanthemums. Further observations indicated that CmGEG restricts cell elongation in the top, middle, and basal regions of the petals. To investigate the relationship between CmGEG and GA in petal growth, we conducted a hormone treatment assay using detached chrysanthemum petals. Our results showed that GA promotes petal elongation while downregulating CmGEG expression. In conclusion, the constrained growth of chrysanthemum petals may be attributed to the inhibition of cell elongation by CmGEG, a process regulated by GA. Full article
