【文章內(nèi)容簡(jiǎn)介】 t al.,2013）在調(diào)控花期上，碳水化合物被認(rèn)為有著中重要的作用。在葉片中，即使受到光周期誘導(dǎo)，TREHALOSE6PHOSPHATE SYNTHASE 1 (TPS1)活性對(duì)于FT誘導(dǎo)來(lái)說(shuō)也是必須的。在頂端分生組織中，T6P途徑能夠通過(guò)年齡途徑直接影響一些重要成花調(diào)控基因表達(dá)，并獨(dú)立于光周期途徑，為分生組織發(fā)育決定和碳水化合物供應(yīng)之間的聯(lián)系提供了一條途徑。在葉片和SAM中，T6P途徑是通過(guò)調(diào)控成花關(guān)鍵基因表達(dá)誘導(dǎo)植物成花的一個(gè)信號(hào)坐標(biāo)。參考文獻(xiàn)1.
