A specific high temperature-induced deficiency of chloroplast ribosome formation, as indicated by the absence of chloroplast rRNA, has been observed in the leaves of light-or dark-grown seedlings of Avena sativa L., Hordeum vulgare L., and Triticum aestivum L. at certain temperatures between 28 and 34 C. While the growth of the leaves (size, morphology, total amino nitrogen content) was little affected by the elevated temperature, chlorophyll accumulation was strongly inhibited, amounting to only 2 to 20% of its content in 22 C-grown leaves which were used as a reference for normal development. The carotenoid contents were also lower but still reached at least 15 to 20% of the
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
