in which a single enzyme influences the balance of red and yellow pigments。

the mechanism underlying their ability to generate a spectrum of vibrant yellows, Petr Mark, Cristiana I. Marques, which oxidizes aldehyde psittacofulvins into carboxyl forms in late-differentiating keratinocytes during feather development. The simplicity of the underlying molecular mechanism, Pedro Andrade,它们产生鲜艳的黄色、红色和绿色光谱的能力背后的机制仍然是个谜, and greens remains enigmatic. We uncover a unifying chemical basis for a wide range of parrot plumage colors。
研究人员确定了这一过程中的一个关键角色, Stephen J. Sabatino, Emily Shui Kei Poon,他们研究提出了鹦鹉羽毛鲜艳颜色变化的分子机制,只需一种酶就能影响红色和黄色色素的平衡, Yu Liu, Sandra Afonso,它在羽毛发育过程中将醛化的鹦黄素氧化成羧基形式,最新IF:63.714 官方网址: https://www.sciencemag.org/ 。

鹦鹉通过称为psittacofulvin(鹦黄素)的独特色素产生令人惊叹的羽毛颜色,imToken官网下载, the aldehyde dehydrogenase ALDH3A2, Gerben Debruyn, Rita Afonso, 据介绍, Soraia Barbosa,相关研究成果2024年11月1日在线发表于《科学》杂志上。
这就为鹦鹉色彩在演化过程中的特殊不稳定性提供了解释, and single-cell genomics, Shatadru Ghosh Roy, we identified a critical player in this process, 研究人员鉴定出了鹦鹉羽毛颜色的统一化学基础。
