This paper summarizes previous work linking protein aggregation to the heterozygosity of organisms. It also cites the literature showing a correlation between species' morphological complexity and the lengths of their proteins. These two findings are combined to form a theory that may potentially explain the ploidy levels of organisms. Organisms can employ heterozygosity to inhibit protein aggr...

BACKGROUND Bacteriophage survives in at least two extremes of ionic environments: bacterial host (high ionic-cytosol) and that of soil (low ionic-environmental water). The impact of ionic composition in the micro- and macro-environments has not so far been addressed in phage biology. RESULTS Here, we discovered a novel mechanism of aggregation/disaggregation transitions by phage virions. When...

ABSTRACT An important strategy for the sustainable management of Cerrado soils is no-till (NT) systems, which may improve soil properties, particularly aggregation. Soil aggregates can be categorized according to their formation pathways into physicogenic (Phy) and biogenic (Bio). This study aimed (i) quantify relative proportion (ii) evaluate levels total organic carbon respective humic physic...

Afforestation influences soil aggregates and the microenvironment, it also affects bacterial communities. However, interactions between aggregation, properties, community that occur following afforestation are still unclear rarely studied in karst ecosystems. Soil samples were collected from cropland, for reference, natural secondary forests managed a rocky desertification region of Southwest C...

Termites are the most important soil fauna in the Sahelian zone of Africa, intensely interacting with the soil. Both the biotic and abiotic state of the soil affect the termite population and activity. The construction by termites of nests, gallery systems or sheetings from soil or from a mixture of soil and other material within the soil horizons or on the soil surface affect the physical and ...

The freeze–thaw cycle can change the size and shape of soil particles, that is, cause fragmentation aggregation mineral thereby affecting structure, which, in turn, affects properties. In addition, process aggregation, as an event closely related to cold climate, plays irreplaceable role reconstructing climatic conditions a certain area period time has important referential significance for res...

Willow (Salix viminalis spp.) shrubs are being planted along riverbanks, on erodible and marginal farmland. Wood chips made from the woody biomass could improve properties of light-textured soils with low organic matter content in potato-based systems. were applied at 0, 20, 40, 60 Mg ha ?1 (fresh weight) as a soil amendment. Soil health parameters evaluated after 12 months, followed by C N con...

Soil aggregates and their stability affect a wide range of soil properties. This study aimed to (a) verify whether biogenic aggregation provides higher macro- microaggregate stabilization, (b) evaluate are associated with labile organic carbon glomalin contents. Three management systems were evaluated (permanent pasture, PP; no-tillage system, NT; + Brachiaria NT+B) as well reference area (Atla...
