Pear Leaves Accumulate Sugars, Potentially Revolutionizing Crop Cultivation and Food Production
Pear leaves can take up sorbitol and glucose from their environment through a transport mechanism. The uptake of these sugars is influenced by factors like tissue age, sugar concentration, and light exposure. Sorbitol and glucose are likely taken up by separate mechanisms. Different plant species have varying abilities to accumulate sorbitol, with some storing it as a specific storage compound. In pear leaves, sorbitol is not well metabolized, while glucose is mostly converted to sorbitol. In contrast, rose leaves metabolize both sorbitol and glucose into sucrose and other compounds. This study sheds light on how different plants handle sugar accumulation and storage.
