喜马拉雅旱獭（Himalayan marmots）是仅分布于青藏高原区域啮齿类动物，在冬季低温食物缺乏季节，它们在每年9-10月进入洞穴冬眠，在次年3月左右恢复活动。在冬眠期消耗体内的脂肪维持基础代谢，因此需要活动期快速增肥，积累足够脂肪。但其生活的环境中，食物季节性变化非常大，与脂肪代谢有关的肝脏是如何适应快速积累脂肪，是一个非常有趣的生理生态过程。
Kalancho? PPC1 is Essential for Crassulacean Acid Metabolism and the Regulation of Core Circadian Clock and Guard Cell Signaling Genes
Crassulacean acid metabolism (CAM) plants oxaloacetate phosphoenolpyruvate carboxylase circadian clock
2024/1/22
Unlike C3 plants, Crassulacean acid metabolism (CAM) plants fix CO2 in the dark using phosphoenolpyruvate carboxylase (PPC; EC 4.1.1.31). PPC combines PEP with CO2 (as HCO3-), forming oxaloacetate tha...
Persulfidation-based Modification of Cysteine Desulfhydrase and the NADPH Oxidase RBOHD Controls Guard Cell Abscisic Acid Signaling
