The effects of decreasing oxygen concentration on growth, polypeptide pattern of newly synthesized proteins and ADH (E.C.1.1.) activity in intact roots of 2 d old wheat seedlings are described and that of rice roots in the same experimental conditions is compared.

Abstract

The effects of decreasing oxygen concentration on growth, polypeptide pattern of newly synthesized proteins and ADH (E.C. 1.1.1.1.) activity in intact roots of 2 d old wheat seedlings are described. These parameters indicated that anaerobic metabolism started when the oxygen concentration in the gas bubbling through the growth medium was between 21% and 10%. With further decrease of the oxygen concentration the rate of anaerobic protein metabolism increased, reaching its height at an oxygen concentration of 1 %. This behaviour is compared with that of rice roots in the same experimental conditions.

186 Citations1971M. MCMANMON, R. M. M. Crawford

A metabolic system of flooding tolerance is formed based on the control of glycolysis through the inductive and kinetic properties of alcohol dehydrogenase and a diversion from ethanol to malate accumulation, dependent upon the presence or absence of ‘malic’ enzyme.

Interspecific differences in the ability of seedlings and rhizomes of higher plants to survive under prolonged and strict anaerobiosis are revealed.

It is concluded that root cells of a hydrophyte are not more tolerant to anoxia than mesophyte, and the ability of hydrophytes to grow on anaerobic soils should be attributed not so much to peculiar features of the roots' metabolism but to the ability to perform an easy transport of O2 from leaves to roots.

When 3 d old aerobic seedlings were subjected to anaerobic conditions the amount of reducing sugars and sucrose in the roots immediately decreased, and the progressive reduction of (both acid and basic) invertase activity in the absence of oxygen is discussed.

Zeitschrift für PflanzenphysiologieSome Effects of Anaerobiosis on Protein Metabolism in Rice Roots

42 Citations1981A. Bertani, Faustino Menegus +1 more

When 3d aerobic rice seedlings were subjected to anaerobiosis, free amino-acid content in the roots increased and their relative concentration changed, resulting in a sharp increase in the rate of protein synthesis and the restoration of the aerobic polypeptide pattern.

27 Citations1982A. Bertani, I. Brambilla

It appear that not all aspects of anaerobic metabolism respond similary to decreasing oxygen concentrations, while for free aminoacid accumulation and for the relative alanine concentration it was between, 2.5% and 1%.

8 Citations1979Raymond E. Girton

In view of the known tolerance of rice to wet soils, in contrast to maize, a comparison of the respiratory responses of the two plants to different O2 concen trations was made and it was found that if the O2 concentration was raised to 100%, an increase was observed in maize root-tip segments and in germinating grains of rice and also in buckwheat.
