Sorghum bicolor adapts to phosphorus (P) deficient soils through mechanisms that contribute to its absorption and solubilization, including the association with microorganisms. The direct application of rock phosphate (RP) and the inoculation with phosphate solubilizing bacteria (PSB) is a sustainable alternative for P supply to the crops. The aim of this study was to evaluate the effect of PSB inoculation of two sorghum genotypes with different P responses (BR007 - efficient and responsive and SC283 - efficient and non-responsive), cultivated in soil fertilized with RP and triple superphosphate (TSP), in greenhouse and field experiments. The sorghum genotypes were inoculated separately with the Bacillus strains that are efficient in P solubilization, B116 and B70, and cultivated under different P fertilization sources (TSP, RP, ½TSP + ½RP). The results suggest that the inoculation response was dependent on sorghum genotype, P source and microbial strain. Inoculation of the genotype BR007 significantly increased root biomass and grain P content under greenhouse conditions, as well as yield and grain P content in field experiments, but no effect was observed on genotype SC283. The use of PSB as bioinoculants, in combination with RP, is a promising alternative to reduce the use of synthetic fertilizers, contributing to the sustainable sorghum production. |

Plants have a variety of active defense mechanisms to protect themselves from pathogen infection. Plant defense response results from the transcriptional activation of a large number of genes upon pathogen infection or treatment with pathogen elicitors. Among them, WRKY proteins are considered important transcriptional regulators in defense signaling, including the activation of SAR (systemic acquired resistance). Several genes regulating plant defense, such as NPR1 and PR (Pathogenesis-related proteins), have W-box elements in their promoters that are specifically recognized by WRKY proteins also required for induction or expression. The defining feature of WRKY transcription factors is their DNA binding domain. The WRKY domain is about 60 residues in length that contains the WRKY signature and also an atypical zinc-finger structure at the C-terminus (Cx4?5Cx22?23HxH or Cx7Cx23HxC). The aim of this work was to identify all potential WRKY transcription factors in citrus, retrieved from the CitEST (Citrus ESTs) database and to construct a phylogenetic tree with orthologs from Arabidopsis thaliana and Oryza sativa. To find ESTs coding for WRKY proteins in citrus we performed a tBLASTn search on the CitEST database. The WRKY domain sequences of seven Arabidopsis WRKY family members each representing one of the WRKY subgroups were used as query sequences. Phylogenetic tree were constructed by the neighbor-joining (NJ) method in MEGA 4. NJ analysis was performed with the Pairwise Deletion option and the Poisson correction. For statistical reliability, bootstrap analysis was conducted with 1,000 replicates to assess statistical support for each node. The primary search resulted in 71 non-redundant hits, of which 9 were removed as they did not contain the conserved WRKY domain signature. The remaining 62 sequences were used to construct the phylogenetic tree; this analysis identified 19 unigenes for the group 1; 6 unigenes for the subgroup 2a, 3 unigenes for the subgroup 2b, 12 unigenes for the subgroup 2c, 13 unigenes for the group 2d, 9 unigenes for subgroup 2e and 7 unigenes for the group 3. To complete the phylogenetic analysis, WRKY sequences from the draft sequencing of the genomes of Citrus clementina and C. sinensis will be included. We are particularly interested in WRKY proteins involved in biotic stress, so the next step will be to evaluate the transcriptional profile of some WRKY genes under different biotic stress conditions. This study will be crucial to select candidates for citrus genetic transformation. MenosPlants have a variety of active defense mechanisms to protect themselves from pathogen infection.
