- Abstract
This article presents the findings of a study on the response of the green alga Serritaenia testaceovaginata to moderate UV radiation. The study used comparative transcriptomics to analyze gene expression in the alga and discovered that it possesses a plant-like system for UV perception and signal transduction, as well as components of major plant photoreceptor systems. This suggests that adaptations to light conditions on land may rely on the adaptation of existing systems rather than the development of new components. The study emphasizes the importance of understanding the genetic and physiological changes that enabled the transition of plants from water to land. Additionally, the study found that genes involved in the production of aromatic amino acids and phenylpropanoid biosynthesis were up-regulated under UV irradiance, indicating a polyphenolic origin of the sunscreen pigment in Serritaenia. The study also identified components of various photoreceptor systems in Serritaenia, including UVR8, which is involved in UV radiation signaling. The authors call for further research on light signaling in non-seed plant species.
