Cucumber carbohydrate metabolism and translocation under chilling night temperature

Low-temperature effect on enzyme activities involved in sucrose–starch partitioning in salt-stressed and salt-acclimated cotyledons of quinoa (Chenopodium quinoa Willd.) seedlings

“…2D and 3D). Leaf starch accumulation induced by low temperature has also been described for other species such as Oryza sativa, Helianthus annuus, Lycopersicon esculentum and Cucumis sativus, among others [26,27]. For these species it has been proposed that decreases in the flux of carbon from source leaves produced by low temperature may indicate a low sink demand as well as a restriction of phloem transport itself by cold.…”

“…Seedlings adapt to salinity and low temperature by different mechanisms, including changes in morphological and developmental pattern as well as physiological and biochemical processes [13,16,26,31,34,40]. Adaptation is associated with maintaining osmotic homeostasis by metabolic adjustments that lead to the accumulation of metabolically compatible compounds such as carbohydrates, polyols, betaines and proline [7,44].…”

Regulation of Photoassimilate Distribution between Source and Sink Organs of Crops through Light Environment Control in Greenhouses

“…At 10˚C of air temperature, translocation of photoassimilates is strongly inhibited. Miao et al reported that compared to cucumbers grown at 22˚C of night air temperature, sucrose, stachyose and galactinol contents increase in mature leaves, while sucrose, glucose and fructose contents in fruits remain unchanged at 12˚C [31]. In peduncles, where stachyose is catabolized to sucrose after long-distance transport, cold night simultaneously induces a significant increase of stachyose and a decrease of sucrose, indicating that the metabolic step from stachyose to sucrose is significantly inhibited in peduncles of cold-night grown cucumbers.…”

Arbutin- and benzotiadiazole-mediated cucumber response to Pseudomonas syringae pv. lachrymans infection in carbohydrate metabolism

“…After long-distance transport to peduncles stachyose is converted to Suc (Miao et al, 2007). Utilization of Suc in cell metabolism depends on its cleavage into hexoses catalyzed, except sucrose synthase (EC 2.4.1.13), by invertase (EC 3.2.1.26).…”
