Small sized ribosomes from mitochondria of locusta migratoria.

Incorporation of amino acids into mitochondrial protein of the flight muscle of Locusta migratoria in vitro and in vivo in the presence of cycloheximide.

The incorporation of arnino acids into distinct protein fractions of mitochondria from various sources [1-4) including a cytoplasmic mutant of Neurospora crassa [5] has been shown tobe an inherent Capacity of isolated mitochondria in vitro. An independent method for studying this system is affered by the specific inhibition of extramitochondrial protein synthesis in vivo. Cycloheximide is known...

Electron Microscope Study of Mitochondrial 60s and Cytoplasmic 80s Ribosomes from Locusta Migratoria

Purified mitochondrial ribosomes (60S) have been isolated from locust flight muscle. Purification could be achieved after lysis of mitochondria in 0.055 M MgCl(2). Mitochondrial 60S and cytoplasmic 80S ribosomes were investigated by electron microscopy in tissue sections, in sections of pellets of isolated ribosomes, and by negative staining of ribosomal suspensions. In negatively stained prepa...

An electron - microscope study of the cytoplasmic inclusions in the neurones of Locusta migratoria

The cytoplasmic inclusions of the neurones of adult Locusta migratoria have been examined in the electron microscope. The mitochondria are easily recognized by their cristae and outer double membranes. Electron-dense inclusions, also with an outer double membrane but possessing numerous closely spaced internal lamellae in various orientations, are probably small lipochondria. Larger and more di...

بررسی تاکسونومی .Locusta migratoria L و تعیین فاز آن در مزارع نیشکر و برنج خوزستان

Concise synthesis of an antifeedant sesquiterpene against Locusta migratoria.

A concise synthesis of (1S*,3R*,6R*)-1-hydroxy-7(14),10-bisaboladien-4-one, an antifeedant against the locust Locusta migratoria isolated from the Japanese cedar Cryptomeria japonica, was achieved by starting from 4-hydroxy-2-cyclohexenone.
