In a backcross population of the allotetraploid Coffea arabica, the loci with diploid-like segregation were predominant, although a few loci with tetrasomic inheritance or distortion of the expected segregation were also observed. A partial genetic map of C. arabica was constructed with 82 RAPD loci scored in this backcross population of 104 individuals. It covered the estimated length of 540.6 cM in 8 linkage groups. The linkage group size was highly correlated with the number of markers, indicating random distribution of the markers in the groups. The average distance between two markers was 7.3 cM.

Concurrent with the population growth, agricultural production tends to grow to meet the food demand. To reset the macro and micronutrients that are removed from the soil in crops chemical fertilizers are constantly applied. The indiscriminate use of phosphate fertilizers, besides being responsible for great environmental impacts; might lead to an early depleting of phosphates rock deposits. With this project, it is expected to demonstrate how the host plant relies on its bacterial community for P uptake and provide cues on how to reduce the use of phosphate fertilizers in agriculture by optimizing the plant uptake through microbiome manipulation. We tested the hypothesis that P-inefficient cultivars, limitation of phosphorus in the soil and phosphate rock supply would enrich the rhizosphere microbiome with microorganisms capable of mobilizing this nutrient. The rhizosphere microbial structure of two cultivars of common bean contrasting in P uptake efficiency, growing in a gradient of triple superphosphate and phosphate rock Bayovar were accessed and evaluated through amplicon sequencing and qPCR. Phosphate doses had a significant effect on bacterial community structure of the rhizosphere. The recruitment of bacteria among doses of phosphorus were different between the cultivars but not between the sources of phosphorus supplied. Preliminary analysis showed that in the cultivar IAC Imperador (P-efficient), Acidobacteriales were more abundant in lower doses of phosphorus while Burkholderiales, Actinomycetales, Bacillales dominated in the higher doses of phosphorus. In the cultivar DOR-364 (P-inefficient) Actinomycetales and Burkholderiales were mainly recruited in the lowest dose of phosphorus while Acidobacteriales and Bacillales were more abundant in the higher doses of phosphorus. Preliminary results suggest that the cultivars of common bean contrasting in P uptake efficiency and limitation of phosphorus in the soil influence the rhizosphere community composition.
