Photosynthetic Units
Leaf tissues of aurea mutants of tobacco and Lespedeza have been shown to have higher photosynthetic capacity per molecule of chlorophyll, a higher saturation intensity, a simpler lamellar structure, and the same quantum yield as their dark green parents. Here we report on the values of photosynthetic units for both types of plants and some algae. The unit has been assumed to be about as unifor...
متن کاملPhotosynthetic units of sun and shade plants.
A computer analysis of fluorescence induction curves of leaves treated with 3-(3,4-dichlorophenyl)-1,1 dimethylurea was done for several species. These measurements gave the ratios of the total chlorophyll to photosystem II reaction centers. This communication is a preliminary survey of sun and shade plants and demonstrates a significant variation in this ratio. In the sun plants, the photosynt...
متن کاملPhotosynthetic Inhibitors
Life on Earth is dependent on sunlight. In the process known as photosynthesis, plants, algae and certain bacterias are capable of using this source of energy to drive the synthesis of organic compounds. The oxygenic photosynthesis results in the release of molecular oxygen and the removal of carbon dioxide from the atmosphere that is used to synthesize carbohydrates. This process, which involv...
متن کاملPhotosynthetic phosphorylation catalyzed by factors isolated from photosynthetic organisms.
where DaUk converges strongly to Dau in L2(Q). Furthermore, daf(uk)Dv converges strongly to da,,(u)Dv in L2(Q) by dominated convergence. Hence, each term in the sum for a (u k, V) converges to the corresponding term in the sum for a(u, v), (G(uk), v)m . (G(u), v)m for each v in V, and the proof of Lemma 3 is complete. Proof of Theorem 1: By Lemma 2, it suffices to show that the mapping G is one...
متن کاملPhotosynthetic Mutant of Lemna
The biosynthesis of the cytochrome b6f complex has been studied in a mutant, no. 1073, of Lemna perpusilla that contained less than 1% of the four protein subunits when compared with a wild-type strain. RNA gel blot analyses of the mutant indicated that the chloroplast genes for cytochrome f , cytochrome b6, and subunit IV (petA, petB, and petD, respectively) are transcribed and that the petB a...
