Sidedness studies of thylakoid phosphatidylglycerol in higher plants.
The transmembrane distribution of phosphatidylglycerol was determined in thylakoids from barley (Hordeum vulgare), lettuce (Lactuca sativa) and pea (Pisum sativum) chloroplasts. Phospholipase A2 and phospholipase D digestion and chemical-labelling methods were used. Phosphatidylglycerol was preferentially localized in the outer (stromal) leaflet. The proportion of the phospholipid in this leafl...
متن کاملHigher Plants
Contamination with 2,4,6-trinitrotoluene (TNT) is widespread at sites of past munitions manufacture. It is moderately toxic to plants and highly toxic to some animals. Some aquatic plant species have been observed to promote degradation of TNT. The degradative activity is associated with the root systems but products are found in the surrounding medium. We have examined a range of sixteen gener...
متن کاملUpdate on Development Gravitropism in Higher Plants
Since 1806, we have known that plant organs use gravity as a guide for growth (Knight, 1806). The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. It also directs roots to grow downward in soil, where they can reach out to take up the water and mineral ions required for ...
متن کاملThe interpretation of studies on rapidly labeled ribonucleic Acid in higher plants.
The properties of at least one class of rapidly labeled RNA, the precursor rRNA, have been well characterized in eucaryotes, particularly in HeLa cells. The initial transcription product of the gene is a large molecule containing one sequence of each of the two stable rRNAs plus additional nonribosomal RNA, the latter being removed during the processing or maturation of the initial transcriptio...
متن کاملATP sulfurylase from higher plants : purification and preliminary kinetics studies on the cabbage leaf enzyme.
ATP sulfurylase was purified extensively from green cabbage (Brassica capitata L.) leaf. The enzyme appears to be an asymmetric dimer composed of 57,000 dalton subunits. Initial velocity and product inhibition studies of the forward and reverse reactions point to an obligately ordered kinetic mechanism with MgATP adding before MoO(4) (2-) (or SO(4) (2-)). and MgPPi leaving before AMP + MoO(4) (...
