Conteúdo:  Endophytic microbes have been proposed to contribute to a range of plant support functions, including nutrient acquisition and disease protection. To date, the molecular mechanisms underlying disease protection in the endosphere have only been studied for individual culturable organisms. Here, we conducted a systematic microbiome-wide perspective on the taxonomic diversity and functional potential of the endophytic microbiome of plants grown in an agricultural soil that is naturally suppressive to damping-off disease caused by the fungal root pathogen Rhizoctonia solani. Metagenomic analyses showed an enrichment of Burkholderiaceae, Chitinophagaceae and Xanthomonadaceae in the endosphere of plants grown in disease-suppressive soil challenged with the fungal root pathogen. Binning of the metagenomic sequences allowed de novo assembly of 25 high quality genomes of different endophytic bacterial genera. Subsequent trait-based analyses revealed numerous biosynthetic gene clusters (BGCs) overrepresented in the endophytic bacterial families of plants under fungal pathogen attack, including BGCs involved in signal transduction and antimicrobial activities, in particular nonribosomal peptides and polyketides. Network analyses further indicated that the traits enriched in the endophytic microbiome are multifactorial involving several novel BGCs encoding metabolites with yet unknown activities.

Título:  Models to estimate potassium and nitrate in changes of ion concentration in soil solution in banana cultivation.

Conteúdo:  The adequate fertigation use bases on the application of nutrients by water according to crop needs throughout its cycle. The evaluation of nutrients in the soil solution may be faster if based upon soil electric conductivity and moisture by using parametric models. The objective of this study was to evaluate the sensitivity of two parametric models for estimating nitrate and potassium concentration in the soil solution under changes of ion concentration during a crop cycle. One model was that from Vogeler et al. (1996) in which ion concentration is a function of soil moisture and electrical conductivity; the other was the potential in which the concentration is a function of the electrical conductivity of the soil solution. The potential model presented a better performance compared to that of adapted from Vogeler, as for estimation of ion concentrations as for the sensitivity of this model to changes in concentration of this ion in the soil solution. The models showed greater sensitivity when fitted to data corresponding to all possible occurrences in the soil during the crop cycle. The model should consider a range of concentrations with the possible values of the soil solution along crop cycle.
