How can you use “dark-grown” in a sentence? Here are some example sentences to help you improve your vocabulary:
Experiments with the model alga Chlamydomonas reinhardtii [ 11 ] showed that LHCPs were not detectably imported into the chloroplast in the absence of Chl synthesis and instead accumulated outside of the chloroplast in the cytosol and in vacuoles [ 12 ] . High concentrations of chloramphenicol caused strong suppression of total Chl synthesis when dark-grown algal cells were exposed to light, possibly by inhibition of Mg-chelatase [ 13 ] in addition to chloroplast protein synthesis.
It is present in tomato leaves, fruits, flowers, light-grown seedlings, and dark-grown seedlings (Fig.
In detail, the progeny of the primary transgenic plant, T1 plant C73, which possessed a single transgene locus as determined by segregation of antibiotic resistance, segregated almost one quarter cop1-like seedlings in the dark-grown T2 generation.
This result, obtained with cells incubated at 25°C, was consistent with localization of LHCPs on envelope membranes in cells immediately after initiation of thylakoid biogenesis at 38°C [ 16 ] . At the higher temperature, not all the newly synthesized LHCPs were incorporated into envelope membranes, and the excess accumulated in cytosolic vacuoles [ 16 17 ] . This evidence for the envelope as the site of initial interaction of LHCPs with Chl was also supported by proliferation of envelope-derived vesicles in dark-grown Chlamydomonas cells exposed to only a few minutes of light [ 18 ] and the lack of thylakoids in a mutant of Arabidopsis deficient in a protein apparently required for formation of vesicles from the inner membrane of the envelope [ 19 ] .
Etioplasts, the form of the plastid that develops in dark-grown plants, were unable to insert LHCPs into membranes unless Chl was added [ 3 ] . In these experiments, in which the Zn derivatives were used because of their increased chemical stability over the Mg-containing molecules, Zn-pheophytin b was more effective in insertion than Zn-pheophytin a.
