Greenhouse gas emissions (CO2, N2O, CH4) and chemical, physical and microbiological properties (pH, macro and micronutrients, texture, moisture, exchangeable NH4+, NO3−, total C and N, organic C, microbial biomass C and metabolic coefficient) were monitored in casts of a large, endogeic native Brazilian earthworm species Rhinodrilus alatus and from noningested control soil incubated for up to 32 days. Earthworm casts represented a significantly different chemical and microbiological environment, with higher soil moisture, pH, H + Al, exchangeable NH4, Cu, Fe and Mn contents, lower microbial biomass C and higher metabolic quotient (qCO2), but with few differences in CO2, N2O andCH4 emissions compared with noningested control soil. Nonetheless, fermenting, methanogenic and nitrate-reducing microbes encountered ideal conditions for sustained anaerobic activity in the clayey, dense and moist castings of R. alatus, maintaining emission of N2O and CH4 and confirming previous results observed using gut contents. The high exchangeable NH4 and H2O contents influenced the oxyreduction processes, affected GHG emissions and N transformations and modified soil microbial biomass and activity. In addition, selective ingestion concentrates C and N contents in the casts and transformation processes affect the availability of important plant nutrients, topics that deserve further attention, considering the widespread collection of this species for use as fish-bait in Brazil. |

The objective of this work was to identify genes that could be used as suitable markers for molecular recognition of phenological stages during coffee (Coffea arabica) fruit development. Four cultivars were evaluated as to their differential Expression of genes associated to fruit development and maturation processes. GEne expression was characterized by both semi?quantitative and quantitative RT?PCR, in fruit harvested at seven different developmental stages, during three different seasons. No size polymorphisms or differential expression were observed among the cultivars for the evaluated genes; however, distinct expression profiles along fruit development were determined for each gene. Four out of the 28 evaluated genes exhibited a regular expression profile in all cultivars and harvest seasons, and, therefore, they were validated as candidate phenological markers of coffee fruit. The gene ??galactosidase can be used as a marker of green stage, caffeine synthase as a marker of transition to green and yellowish?green stages, and isocitrate lyase and ethylene receptor 3 as markers of late maturation. |
