Established vineyard soils may have high copper (Cu) contents due to the ongoing foliar applications of copper-based fungicides. In viticulture, the replacement of old vineyards with new vines is common practice, however,limited by Cu excess in soil and its toxicity to young grapevines. The application of phosphorus (P) and ar-buscular mycorrhizal fungi (AMF) inoculation are potential strategies to reduce Cu toxicity to young grapevines.This study aimed to assess the effects of phosphorus fertilization and AMF (Rhizophagus clarus) inoculation ongrowth and physiological parameters of young grapevines grown in soil with high Cu content. The experimentwas conducted in a greenhouse, where natural grassland soil was artificially contaminated by the addition of60 mg kg−1Cu. The soils were treated with and without AMF inoculation, combined with additions of 0, 40 and100 mg P kg−1. After 90 days of cultivation, grapevine plants were assessed for chlorophyllafluorescence,photosynthetic pigment contents, superoxide dismutase (SOD) activity, plant height, plant biomass, and con-centrations of Cu and P in roots and shoots. Phosphorus fertilization promoted increases in seedling growth(related to the increase of total P concentration in roots and shoots), soluble Pi concentration in leaves, and thequantum yield of the PSII (YII) (associated with a reduction in shoot Cu concentration). The AMF inoculationincreased the concentration of P in roots and shoots, soluble Pi in leaves and electron transport rate (ETR).Phosphorus fertilization and inoculation of grapevines with AMF are strategies capable of reducing Cu toxicity inyoung grapevines.

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.
