Timelapse microscopy has recently been employed to study the metabolism and physiology of cyanobacteria at the single-cell level. However, the identification of individual cells in brightfield images remains a significant challenge. Traditi...
Aquatic plant Myriophyllum spicatum displays contrasting morphological, photosynthetic, and transcriptomic responses between its aquatic and terrestrial morphotypes [0.03%]
水生植物(Myriophyllum spicatum)的水生和陆生生境下的形态、光合特性及转录组学特征差异响应分析
Huan Xu,Wei Li,Wenlong Fu et al.
Huan Xu et al.
Myriophyllum spicatum, a semi-aquatic plant, can develop heterophylly by forming both submerged and aerial leaves to adapt to water level variations in its habitat. The aerial leaves exhibit shorter and fewer lobes, but thicker cuticle and ...
