563. 蛇菰:打破规则的寄生植物界异类
from 知为谁 · host 知为谁
这项研究揭示了蛇菰这一奇特植物的生物奥秘,它因外形酷似蘑菇且完全放弃了光合作用而备受瞩目。作为一种通过寄生树木根部获取养分的古老物种,蛇菰在进化过程中极度简化了其基因组,却保留了与疟原虫类似的微型质体结构以维持生命。科研人员发现,某些岛屿种群甚至演化出了无需受精的无性繁殖能力,以此在极端的生态位中繁衍。尽管这种独特的生存策略使其延续了亿年之久,但高度的寄生依赖性也让该植物在面对栖息地破坏时显得尤为脆弱。这项多国合作的研究不仅梳理了其演化脉络,更为保护这些稀有且脆弱的寄生植物提供了科学依据。内容来源:https://www.sciencedaily.com/releases/2025/12/251219093322.htm
