Abstract

, a significant woody oil crop in southern China, produces oil from its fruit seeds. Understanding sugar metabolism enzyme regulation is crucial for sugar accumulation and oil synthesis in fruit organs. This study examines the dynamic changes in sugar metabolism across four developmental stages of fruits, from rapid fruit enlargement to oil conversion. We analyzed sugar content, enzyme activity, and transcriptomic data to identify key periods and mechanisms involved in sugar metabolism. Our findings indicate that photosynthetic products are rapidly transported from leaves to fruit organs after synthesis, with transport efficiency decreasing significantly after 48 hours. September was identified as a critical period for oil conversion, during which the highest sucrose levels and SuSy-II enzyme activity were detected in the kernels. A positive correlation was found between high expression of ten genes related to sugar metabolism enzymes and sugar transport proteins and sucrose content. Notably, the expression levels of c158337.graph_c0 (SPS), c166323.graph_c0 (SuSy), c159295.graph_c0 (SUC2-like), and c156402.graph_c0 (SUC2-like) significantly increased during the oil conversion phase.These findings provide a crucial theoretical foundation for elucidating the molecular mechanisms of sugar metabolism in fruits, offering insights that could enhance its economic yield.

摘要

作为中国南方一种重要的木本油料作物，通过其果实种子产油。了解糖代谢酶调控对于果实器官中的糖分积累和油脂合成至关重要。本研究考察了果实从快速膨大到油脂转化的四个发育阶段糖代谢的动态变化。我们分析了糖含量、酶活性和转录组数据，以确定参与糖代谢的关键时期和机制。我们的研究结果表明，光合产物合成后迅速从叶片运输到果实器官，48小时后运输效率显著下降。9月被确定为油脂转化的关键时期，在此期间，籽粒中检测到最高的蔗糖水平和蔗糖合成酶-II（SuSy-II）活性。发现与糖代谢酶和糖转运蛋白相关的十个基因的高表达与蔗糖含量呈正相关。值得注意的是，在油脂转化阶段，c158337.graph_c0（蔗糖磷酸合成酶，SPS）、c166323.graph_c0（蔗糖合成酶，SuSy）、c159295.graph_c0（类SUC2）和c156402.graph_c0（类SUC2）的表达水平显著增加。这些发现为阐明果实糖代谢的分子机制提供了重要的理论基础，为提高其经济产量提供了见解。
