The Date Palm Tree Rhizosphere Is a Niche for Plant Growth Promoting Bacteria in the Oasis Ecosystem
Table 1
Environmental factors associated to the structure of the date palm soil bacterial community. Relationships between bacterial assemblages and climate features using nonparametric multivariate multiple regression analysis (DISTLM). (a) Marginal test considers each single geographical variables and their contribution to explain the total variability. (b) Sequential test explaining the total variation with the contribution of all the variables accounted together. Lat. N: latitude north; Long. E: longitude east; Alt.: altitude; : minimum temperature; : maximum temperature; Rainfall min: minimum rainfall; Rainfall max: maximum rainfall; : statistic ; : probability (in bold the variables statistically significant; ); Prop.: proportion of total variation explained; Cumul.: cumulative variation explained by the variables listed; Res df: residual degrees of freedom.
