主要成果:

一个新的物种,Aulopus chirichignoae sp. 描述,此前与Aulopus bajacali.混.
关键的区分特征包括男性背射线显著延长,头部尺寸较小,射线数量的模态差异,脊椎数量较高和鲜明的色彩.
通过DNA条形码确认了新物种的身份,与Aulopus filamentosus和A. bajacali分别有4.2%和2.8%的遗传差异.
新物种的分布范围延伸到热带东太平洋的Paramount海山,距加拉帕戈斯群岛以北约400公里.

结论:

艾洛普斯 (Aulopus chirichignoae) sp. 在这里可以看到. nov. 代表了Aulopidae家族中一个独特的新物种.
形态和遗传数据证实了其独特的地位,并将其与同类区分开来.

Channel Rhodopsins

Channel Rhodopsins

Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...

Red Algae

Red Algae

Red algae, also known as rhodophytes, are primarily found in marine environments, though some species inhabit freshwater and terrestrial ecosystems. These organisms exist in both unicellular and multicellular forms, with some multicellular varieties reaching macroscopic sizes.As phototrophic organisms, red algae contain chlorophyll a; however, their chloroplasts lack chlorophyll b. Instead, they possess phycobiliproteins, which serve as major light-harvesting pigments, similar to those found in...
