متن کاملNitrogenase Activity and Amounts of Nitrogenase Proteins in a Frankia-Alnus incana Symbiosis Subjected to Darkness.
Effects of prolonged darkness on nitrogenase activity in vivo, nitrogenase activity in vitro, and the amounts of nitrogenase proteins were studied in symbiotic Frankia. Plants of Alnus incana (L.) Moench in symbiosis with a local source of Frankia were grown for 9 to 10 weeks in an 18/6 hour light/darkness cycle. After 12 hours of a light period, the plants were exposed to darkness for up to 40...
متن کاملUptake, metabolism and distribution of organic and inorganic nitrogen sources by Pinus sylvestris.
Although an increasing number of studies show that many plant species have the capacity to take up amino acids from exogenous sources, the importance of such uptake for plant nitrogen nutrition is largely unknown. Moreover, little is known regarding metabolism and distribution of amino acid-N following uptake or of the regulation of these processes in response to plant nitrogen status. Here res...
متن کاملNitrogen Fixation by Ceanothus.
The rapidity of successioni of Ceanothus species in burned-over areas where they are indigenous and the apparent enhancing effect which these species have on the development of other shrubs and ground cover suggests that Ceanothus has a soil-improvement effect and implies the fixation of nitrogen. Nodulation of some species of Ceanothus was observed as early as 1912 (3). Bottomley and also Petr...
