The formation of homogentisate in the biosynthesis of tocopherol and plastoquinone in spinach chloroplasts [PDF]
, 1982 Homogentisate is the precursor in the biosynthesis of -tocopherol and plastoquinone-9 in chloroplasts. It is formed of 4-hydroxyphenylpyruvate of the shikimate pathway by the 4-hydroxyphenylpyruvate dioxygenase.

A ‘foldosome’ in the chloroplast? [PDF]
Plant Signaling & Behavior, 2009 The proper functioning of many cytosolic proteins involved in signal transduction depends on protein folding steps carried out cooperatively by a multichaperone complex containing the Hsp90 and Hsp70 machineries. We have recently found that also in the chloroplast the Hsp90 and Hsp70 machineries form a multichaperone complex, although chloroplast Hsp90

Frontiers in Plant Science, 2020 The plastid terminal oxidase (PTOX) – an interfacial diiron carboxylate protein found in the thylakoid membranes of chloroplasts – oxidizes plastoquinol and reduces molecular oxygen to water. It is believed to play a physiologically important role in the

Phytol synthesis from geranylgeraniol in spinach chloroplasts [PDF]
, 1981 The reduction of /2-14C/-geranylgeranylpyrophosphate to phytylpyrophosphosphate is shown for the first time in chloroplasts. The esterification of exogenous /2-14C/-geranylgeranylpyrophosphate with endogenous chlorophyllide and the stepwise reduction of ...

Faraday Discussions of the Chemical Society, 1979 The principal function of the chloroplast is to capture solar quanta and to store them in some stable form. We are in the process of trying to construct a totally synthetic system that would simulate some of the reactions of the two photosystems which occur in natural chloroplasts.

Chloroplast SRP54s are Essential for Chloroplast Development in Rice [PDF]
Rice, 2020 Abstract Background The chloroplast signal recognition particle 54 (cpSRP54) is known for targeting the light-harvesting complex proteins to thylakoids and plays a critical role for chloroplast development in Arabidopsis, but little is known in rice.

SHORT-TERM CHILLING OF WHEAT SEEDLINGS OR ROOTS AFFECTS THE ULTRASTRUCTURE OF MESOPHYLL CELLS
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2017 The effects of short-term chilling (2°C, 10 min) of seedlings or roots of wheat (Triticum aestivum L.) on the cold tolerance and ultrastructure of mesophyll cells were studied under controlled conditions.
