Niederpruem, Donald J. (Indiana University Medical Center, Indianapolis). Respiration of basidiospores of Schizophyllum commune. J. Bacteriol. 88:210-215. 1964.-The aerobic metabolism of basidiospores of the wood-rotting mushroom Schizophyllum commune was investigated by use of manometric techniques and specific respiratory poisons. Basal respiration was stimulated markedly by the uncoupling ag...

We report the recent isolation of Cryptococcus laurentii from the blood of a patient given the diagnosis of ganglioneuroblastoma. The organism was identified using physiological and molecular characteristics, including morphology, carbohydrate and nitrate assimilation, urease activity, inability to form melanin on appropriate media, positive staining with diazonium blue B and sequence analysis ...

A major spawning ground of the European anchovy (Engraulis encrasicolus) population in the Bay of Biscay is located near the mouth of the Gironde estuary. Variations in the river discharge affect the supply of nutrients to the coastal marine area encompassing anchovy spawning grounds. Two “Pegase” cruises (May–June 1997 and 1998) observed two contrasting situations: with and without a superfici...

In a two-year field study, we quantified the impact of post-flowering soil waterlogging on carbon assimilation and grain yield formation in wheat crops. At anthesis, cultivars YangMai 18 (YM18) YanNong 19 (YN19) were waterlogged for different durations, i.e., 0 (W0), 3 (W3), 6 (W6) 9 (W9) days using artificial structures. Changes leaf physiology, biomass production at 0, 7, 14, 21 after anthesi...

Drought is expected to become an increasingly important factor limiting tree growth caused by climate change. Two divergent clones of Populus nigra (58-861 and Poli) originating from contrasting environments were subjected to water limitation (WL) to elucidate whether they differ in tolerance to drought, which mechanisms to avoid stress they exhibit and whether drought has an impact on the inte...

Woody perennials subjected to root oxygen-stress often respond with varying levels of reduced assimilation and leaf gas exchange. Yet in most of these studies, seedlings grown in pots were subjected to experimental conditions that rarely exist in nature for mature trees. To determine if flooding mature orchard-grown pecan (Carya illinoiensis (Wangh) K. Koch) results in a similar depressed photo...

The effect of potassium supply of Vicia faba on the fixation of molecular nitrogen by root nodules was studied by using (15)N-labeled molecular nitrogen. Plants well supplied with potassium showed higher contents of (15)N in the soluble amino fraction and in the protein fraction of various plant organs as compared with plants of a lower potassium status. This effect was evident particularly in ...

The Roseobacter clade of aerobic marine proteobacteria, which compose 10-25% of the total marine bacterial community, has been reported to fix CO(2), although it has not been determined what pathway is involved. In this study, we report the first metabolic studies on carbohydrate utilization, CO(2) assimilation, and amino acid biosynthesis in the phototrophic Roseobacter clade bacterium Roseoba...
