Lipid Composition of Pea and Bean Leaves during Chloroplast Development.
The changes in composition of the complex lipids were followed during the greening of dark-grown pea (Pisum sativum) and bean (Phaseolus vulgaris) seedlings. No significant changes in glycerolipid concentrations in the leaves were observed during the early stages of greening (0-8 hour for peas and 0-12 hour for beans). On further greening, there was an increase in the proportion of galactolipid...
متن کاملDark CO2 Fixation in Avocado Roots, Leaves, and Fruit
In a previous study avocado roots fixed CO2 about as rapidly as orange and lemon roots but much slower than bean roots (2). However, homogenates of avocado roots or leaves did not fix CO2. This study was made to explore reasons for the failure of homogenates of avocado to show CO2 fixation, and also to understand more of the relatively low degree of CO2 fixation by avocado roots in. case it may...
متن کاملHydrogen peroxide synthesis in isolated spinach chloroplast lamellae : an analysis of the mehler reaction in the presence of NADP reduction and ATP formation.
Light-dependent O(2) reduction concomitant with O(2) evolution, ATP formation, and NADP reduction were determined in isolated spinach (Spinacia oleracea L. var. America) chloroplast lamellae fortified with NADP and ferredoxin. These reactions were investigated in the presence or absence of catalase, providing a tool to estimate the reduction of O(2) to H(2)O(2) (Mehler reaction) concomitant wit...
متن کاملTendril-less regulates tendril formation in pea leaves.
Tendrils are contact-sensitive, filamentous organs that permit climbing plants to tether to their taller neighbors. Tendrilled legume species are grown as field crops, where the tendrils contribute to the physical support of the crop prior to harvest. The homeotic tendril-less (tl) mutation in garden pea (Pisum sativum), identified almost a century ago, transforms tendrils into leaflets. In thi...
متن کاملArrangement of photosystem II and ATP synthase in chloroplast membranes of spinach and pea.
We used cryoelectron tomography to reveal the arrangements of photosystem II (PSII) and ATP synthase in vitreous sections of intact chloroplasts and plunge-frozen suspensions of isolated thylakoid membranes. We found that stroma and grana thylakoids are connected at the grana margins by staggered lamellar membrane protrusions. The stacking repeat of grana membranes in frozen-hydrated chloroplas...
