[求助] 求高手翻譯一下，自己雖然能看懂大概但不能用漢語準(zhǔn)確表述。

As part of an elaborate signaling system, the phloem translocation stream contains a large population of RNA molecules and proteins, suggesting that plants use mobile RNAs and proteins to integrate developmental processes at the whole-plant level. Because of the phloem’s involvement in the production and collection of signal molecules in source organs and in transporting and releasing them to sink organs, the phloem exhibits great potential to facilitate interorgan coordination and to mediate processes of development. This chapter focuses on three model systems as primary examples of noncell autonomous movement of protein or full-length mRNAs that impact plant development. The first example is the long-distance transport of FLOWERING LOCUS T (FT) protein to the apical shoot to induce flowering. The second example involves aRNA–protein complex of pumpkin (Cucurbita maxima) that moves CmGAI and other full-length mRNAs. In this system, a polypyrimidine tract-binding protein, designated CmRBP50, serves as the core RNA-binding protein in a phloem–mobile complex. The final example is the transport of Solanum tuberosum BEL5 (StBEL5) RNA from leaves to stolon tips to activate tuber formation in potato (Solanum tuberosum). StBEL5 is a transcription factor that functions in tandem with Knotted1-like proteins. These examples represent complex and dynamic phloem transport systems involving RNA–protein
and protein–protein interactions that facilitate directed movement and maintain the integrity of the signal molecules.

作為精巧信號(hào)系統(tǒng)的一部分，韌皮部運(yùn)輸流中含有大量RNA分子和蛋白質(zhì)，說明植物在植株水平上利用可移動(dòng)RNAs和蛋白來整合發(fā)育進(jìn)程。由于韌皮部參與源器官中信號(hào)分子的產(chǎn)生和收集及其向庫器官的運(yùn)輸和釋放，韌皮部在促進(jìn)器官間協(xié)調(diào)作用及介導(dǎo)發(fā)育進(jìn)程方面發(fā)揮巨大的潛在作用。本章集中在3個(gè)模式系統(tǒng)上，作為影響植物發(fā)育的蛋白或全長(zhǎng)mRNAs的非細(xì)胞自主移動(dòng)的主要例子。第一個(gè)例子是開花位點(diǎn)（FT）蛋白向莖尖長(zhǎng)距離運(yùn)輸誘導(dǎo)開花。第二個(gè)例子論及南瓜(Cucurbita maxima)中一個(gè)RNA-蛋白復(fù)合體移動(dòng)CmGAI及其他全長(zhǎng)mRNAs。該系統(tǒng)中，多聚嘧啶區(qū)結(jié)合蛋白CmRBP50是韌皮部移動(dòng)復(fù)合體中核心的RNA結(jié)合蛋白。最后一個(gè)例子是馬鈴薯（Solanum tuberosum）BEL5(StBEL5)RNA從葉片向匍匐莖尖運(yùn)輸，激活馬鈴薯塊莖形成。StBEL5是一個(gè)轉(zhuǎn)錄因子，和類Knotted1蛋白共同發(fā)揮作用。這些例子代表了復(fù)雜、動(dòng)態(tài)的韌皮部運(yùn)輸系統(tǒng)，包括RNA-蛋白、蛋白-蛋白互作促進(jìn)定向移動(dòng)，并維持信號(hào)分子的完整性。
