Exogenous ABA and its inhibitor regulate flower bud ... - Springer
2021年1月3日 · Exogenous ABA increased the flowering rate and advanced the flower formation of “Fuji” apple cv. “Nagafu No.2” by promoting the accumulation of soluble sugar, glucose and sucrose, and also increased the activities of α-AMY and SPS.
Abscisic Acid and Flowering Regulation: Many Targets ... - PubMed
2020年12月18日 · In the leaf, ABA signaling affects flowering genes responsible for the production of the main florigen FLOWERING LOCUS T (FT). At the shoot apex, FD and FD-like transcription factors interact with FT and FT-like proteins to regulate ABA responses.
Molecular regulatory events of flower and fruit abscission in ...
2023年10月1日 · Abscisic acid (ABA) is closely related to plant stress responses. ABA might be involved in the regulation of flower and fruit abscission (Mornya and Cheng, 2018). During shade-induced apple abscission, some ABA biosynthesis genes (NCED, SDR, AAO, etc.) were significantly changed (Zhu et al., 2011).
Abscisic acid promotes flowering and enhances LcAP1 expression …
2013年9月1日 · When trees were treated with ABA before panicle primordia emerged, the number of flowers per panicle in the ABA-treated trees was higher than that of the control. The ABA biosynthesis inhibitor naproxen reduced the percentage of flowering terminal shoots and number of flowers in one panicle, and suppressed the litchi homologue gene ( LcAP1 ).
经典案例 | 蛋白质组、转录组和代谢组综合分析揭示GA-ABA调控 …
2024年4月3日 · 为了揭示aba对花芽发育的调控功能，研究人员比较了aba及其抑制剂处理前后花芽的转录组，并筛选了差异表达基因。 其中， CsAP1 及其共表达的与花发育/激素信号转导相关的基因的差异表达变化最为显著。
藤本月季“安吉拉”花芽分化形态结构及内源激素变化研究
内源激素测定结果表明：ABA、CTK浓度在萼片原基分化期显著升高与花芽分化诱导有关，较低的IAA浓度以及GA浓度的降低有利于藤本月季“安吉拉”的花芽分化；萼片原基分化期CTK/GA和（ABA+CTK）/GA比值升高可能与花芽分化诱导有关，高水平的IAA/ABA和IAA/GA比值可能与花器官原基的进一步发育相关。 关键词: 月季, 花芽分化, 形态结构, 内源激素....
Abscisic Acid and Flowering Regulation: Many Targets, Different …
2020年11月24日 · Plants can react to drought stress by anticipating flowering, an adaptive strategy for plant survival in dry climates known as drought escape (DE). In Arabidopsis, the study of DE brought to surface the involvement of abscisic acid (ABA) in controlling the floral transition.
Integrated proteomic, transcriptomic, and metabolomic profiling …
2024年3月12日 · To reveal the regulatory function of ABA in flower bud development, we compared the transcriptome of flower buds before and after treatment with ABA and its inhibitors and screened for differentially expressed genes (DEGs).
Bud endodormancy in deciduous fruit trees: advances and prospects …
2021年6月1日 · In this review, we focus on the molecular regulation of endodormancy induction, maintenance and release in floral buds of deciduous fruit trees. We also describe recent advances in quantitative...
Exogenous ABA and its inhibitor regulate flower bud induction of …
2021年1月3日 · ABA plays important roles in the flower bud induction of fruit trees. However, the effect of exogenous ABA on flower… CEPA significantly repressed the vegetative growth attributed to the increase of ABA and ZT synthesis, and the decrease of IAA synthesis in leaves and buds, and was more susceptible to easy-flowering M.26/M.
