Abstract
Erythrotrichia bohanensis Huang, Chu et Ding is a recently reported new species, with the type specimen originating from Qinhuangdao, China. Being a lower filamentous red alga, it lives an epiphytic life. In this study, E. bohanensis was isolated from red and brown macroalgae collected in Qinhuangdao, Hebei, in spring 2023. They were cultured under laboratory conditions, and their life cycle was an alternation of sporophyte and gametophyte generations. Thalli are monoecious, with mature gametophytes producing carpogonia and spermatangia. Spermatangia release spermatia through “post-maturation” (maturation after detachment from the thallus) and “over-maturation” (maturation within the thallus). Fertilization occurs between sperms and ova outside the thallus or on the thallus surface, and the zygote germinates to form the sporophyte. Mature sporophytes release monospores, which germinate into gametophytes outside the thallus. This study first reports the life cycle of the new species E. bohanensis, supplementing the sexual reproductive structures and early life history pathways of the genus Erythrotrichia. It also enriches understanding of the diverse reproductive strategies and life history processes that characterize the adaptive capabilities of lower marine red algae to their environments.
期刊介绍:
Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. Algae is defined to include cyanobacteria, microalgae, and protists and symbionts of interest in biotechnology. The journal publishes original research and reviews for the following scope: algal biology, including but not exclusive to: phylogeny, biodiversity, molecular traits, metabolic regulation, and genetic engineering, algal cultivation, e.g. phototrophic systems, heterotrophic systems, and mixotrophic systems, algal harvesting and extraction systems, biotechnology to convert algal biomass and components into biofuels and bioproducts, e.g., nutraceuticals, pharmaceuticals, animal feed, plastics, etc. algal products and their economic assessment
