Higher plant mitochondria
Over the past 20 years, researchers investigating the mitochondria of plants have been astonished by the phenomenal variation these organelles display relative to their mammalian and fungal counterparts. Plant mitochondria have evolved distinct strategies for genome maintenance, genetic decoding, gene regulation, and organelle segregation. Their physiological and biochemical functions have simi...
متن کاملProtein synthesis in plant mitochondria.
Plant mitochondria can incorporate amino acids into protein (1, 2), but the details of the process are lacking, although the situation is somewhat clearer with mitochondria from animal source (3-6). The present paper is concerned with the incorporation of amino acids by the mitochondria from the seedlings of Vigna &ens-is (Linn.) Savi and also with the role of the microsomal fraction in this pr...
متن کاملRNA metabolism in plant mitochondria.
Mitochondria are essential for the eukaryotic cell and are derived from the endosymbiosis of an α-proteobacterial ancestor. Compared to other eukaryotes, RNA metabolism in plant mitochondria is complex and combines bacterial-like traits with novel features that evolved in the host cell. These complex RNA processes are regulated by families of nucleus-encoded RNA-binding proteins. Transcription ...
متن کاملOxaloacetate and malate transport by plant mitochondria.
The permeability of mitochondria from pea (Pisum sativum L. var Kleine Rheinländerin) leaves, etiolated pea shoots, and potato (Solanum tuberosum) tuber for malate, oxaloacetate, and other dicarboxylates was investigated by measurement of mitochondrial swelling in isoosmolar solutions of the above mentioned metabolites. For the sake of comparison, parallel experiments were also performed with r...
متن کاملEffects of rotenoids on isolated plant mitochondria.
The effects of several rotenoids have been studied on potato (Solanum tuberosum L.) tuber and etiolated mung bean (Phaseolus aureus Roxb.) hypocotyls mitochondria. The selective inhibition of mitochondrial complex I is characterized by several tests: (a) no effect can be observed on exogenous NADH or succinate oxidation; (b) malate oxidation is inhibited at pH 7.5; (c) one-third decrease of ADP...
