Light is crucial for flower bud development in plants, serving as both signal and energy source. However, the mechanisms by which daylength and light intensity regulate flowering in modern roses remain unclear. In Rosa hybrida 'Carola', insufficient light delays flowering and reduces the sugar content in terminal buds.

- - The root of a plant contains oleanolic acid glycosides as the main type of saponins, and a specific gene family is crucial for converting β-amyrin into oleanolic acid, although research on these genes is limited.
- - In this study, 22 genes were found, divided into seven subfamilies, with four specific genes showing significant involvement in saponin synthesis as indicated by RNA-seq analysis and subcellular localization studies.
- - Overexpressing these four genes in transgenic hair roots led to increased saponin compounds and supported the idea that these genes enhance oleanolic acid production by activating related upstream genes involved in triterpenoid biosynthesis.
A. DC, known for its saponin content, can potentially prevent and treat cerebrovascular diseases and COVID-19. Triterpenoid saponin biosynthesis in plants is enhanced by methyl jasmonate (MeJA) application.

- * A study identified 23 candidate genes related to this gene family in a particular plant's genome, analyzing their distribution across chromosomes, phylogenetic relationships, and expressions in different plant tissues.
- * Key genes (7, 9, and 12) were found to be highly expressed in swollen tubers, confirmed to be present on the cell membrane, suggesting their involvement in tuber formation and offering insights for future research and molecular breeding.
Trehalose, trehalose-6-phosphate synthase (TPS),and trehalose-6-phosphatase (TPP) have been reported to play important roles in plant abiotic stress and growth development. However, their functions in the flowering process of have not been characterized. In this study we found that, under a short photoperiod or weak light intensity, the content of trehalose in the shoot apical meristem of cv 'Carola' significantly decreased, leading to delayed flowering time.
