Bacteria-phage antagonistic coevolution in soil.
Bacteria and their viruses (phages) undergo rapid coevolution in test tubes, but the relevance to natural environments is unclear. By using a "mark-recapture" approach, we showed rapid coevolution of bacteria and phages in a soil community. Unlike coevolution in vitro, which is characterized by increases in infectivity and resistance through time (arms race dynamics), coevolution in soil result...
متن کاملDifferential Soil Acidity Tolerance of Tropical Legume Cover Crops
In tropical regions, soil acidity and low soil fertility are the most important yield-limiting factors for sustainable crop production. Using legume cover crops as mulch is an important strategy not only to protect the soil loss from erosion but also to ameliorate soil fertility. Information is limited regarding tolerances of tropical legume cover crops to acid soils. A greenhouse experiment wa...
متن کاملInfluence of Cover Crops on Populations of Soil Nematodes
Wang, Q., Y. Li, Z. Handoo, and W. Klassen. 2007. Influence of cover crops on populations of soil nematodes. Nematropica 37:79-92. A pot experiment was carried out in south Florida to elucidate suppressive or antagonistic effects of several cover crops grown in rotation on soil nematode populations. The crops were two marigolds, Tagetes patula L. ‘Dwarf Double French Mix’ (MDF), and Tagetes pat...
متن کاملAntagonistic interaction networks among bacteria from a cold soil environment.
Microbial antagonism in an Arctic soil habitat was demonstrated by assessing the inhibitory interactions between bacterial isolates from the same location. Of 139 isolates obtained from five soil samples, 20 antagonists belonging to the genera, Arthrobacter, Pseudomonas and Flavobacterium were identified. Inter-genus, inter-species and inter-strain antagonism was observed between the interactin...
متن کاملCultivation of globally distributed soil bacteria from phylogenetic lineages previously only detected in cultivation-independent surveys.
The culturability of microorganisms in a 10 cm core of an Australian pasture soil was investigated using a minimal agar medium with xylan as the growth substrate. Culturability decreased with increasing depth, from a maximum of 19% of the total microscopically countable cells in the 0-2 cm section to 2.4% in the 8-10 cm section. Seventy-one isolates from the core were identified by comparative ...
