Mimosa tenuiflora (Willd.) Poir. is widespread in southern and central American drylands, but little information is available concerning its associated rhizobia. Therefore, this study aimed to characterize M. tenuiflora rhizobia from soils of the tropical dry forests (Caatinga) in Pernambuco State, Brazil, at the molecular and symbiotic levels. Soil samples of pristine Caatinga areas in four municipalities were used to grow M. tenuiflora. First, the bacteria from root nodules were subjected to nodC/nifH gene amplification, and the bacteria positive for both genes had the 16S rRNA gene sequenced. Then, ten strains were evaluated using recA, gyrB, and nodC gene sequences, and seven of them had their symbiotic efficiency assessed. Thirty-two strains were obtained and 22 of them were nodC/nifH positive. Twenty strains clustered within Paraburkholderia and two within Rhizobium by 16S rRNA gene sequencing. The beta-rhizobia were similar to P. phenoliruptrix (12) and P. diazotrophica (8). Both alpha-rhizobia were closely related to R. miluonense. The recA + gyrB phylogenetic analysis clustered four and five strains within the P. phenoliruptrix and P. diazotrophica branches, respectively, but they were somewhat divergent to the 16S rRNA phylogeny. For Rhizobium sp. ESA 637, the recA + gyrB phylogeny clustered the strain with R. jaguaris. The nodC phylogeny indicated that ESA 626, ESA 629, and ESA 630 probably represented a new symbiovar branch. The inoculation assay showed high symbiotic efficiency for all tested strains. The results indicated high genetic diversity and efficiency of M. tenuiflora rhizobia in Brazilian drylands and included P. phenoliruptrix-like bacteria in the list of efficient beta-rhizobia in the Caatinga biome.

Evapotranspiration (ET) is normally considered as the sum of all water that evaporates from the soil and transpires from plants. However, accurately estimating ET from complex landscapes can be difficult because of its high spatial heterogeneity and diversity of driver factors, which make extrapolation of data from a point to a larger area quite inaccurate. In this paper, we hypothesize that MODIS products can be of use to estimate ET in areas of Caatinga vegetation, the hydrology of which has not been adequately studied. The experiment was conducted in a preserved level area of Caatinga in which meteorological and water flux measures were taken throughout 2012 by eddy covariance. Evapotranspiration estimates fromeddy covariance were comparedwith remotely sensed evapotranspiration estimates from MOD16A2 and SAFER products. Correlations were performed at monthly, 8-day, and daily scales; and produced ??2 values of monthly scale = 0.92, 8-day scale = 0.88, and daily scale = 0.85 for the SAFER algorithm. Monthly MOD16A2 data produced a value of ??2 = 0.82, and they may be useful because they are free, downloadable, and easy to use by researchers and governments. |
