Carotenoids belong to the widespread group of lipophilic tetraterpenoids that play essential roles in plants, microbes, and animals. In photosynthetic microalgae and cyanobacteria, carotenoids are the fundamental components of photosynthesis and protect these organisms from excess radiations, and oxidative stress. Also, polar xanthophyll carotenoids are well known to regulate the biophysical properties of cellular membranes with respect to corresponding changes in temperature. In Zygomycetes fungi, carotenoids-derived trisporoids play crucial roles in early sexual reproduction and mycelial development. Considering these multifaceted roles, carotenoids are widely researched on. In this article, we highlighted the emerging roles of carotenoids in the survival and adaptations of microalgae, bacteria, and fungi under normal as well as extreme environmental conditions.
类胡萝卜素属于广泛存在的亲脂性四萜类化合物，在植物、微生物和动物中发挥着重要作用。在光合微藻和蓝细菌中，类胡萝卜素是光合作用的基本组成部分，可保护这些生物体免受过量辐射和氧化应激的影响。此外，众所周知，极性叶黄素类胡萝卜素可根据温度的相应变化调节细胞膜的生物物理特性。在接合菌纲真菌中，类胡萝卜素衍生的三孢酸在早期有性生殖和菌丝体发育中起关键作用。鉴于这些多方面的作用，人们对类胡萝卜素进行了广泛的研究。在本文中，我们重点介绍了类胡萝卜素在正常以及极端环境条件下微藻、细菌和真菌的生存与适应过程中所发挥的新作用。
