ABSTRACT.
The search for environmentally biocompatible and cost-effective methods to control filamentous fungi in agriculture is becoming increasingly urgent. In vitro antimicrobial activity of three synthetic peptides was investigated against some filamentous fungi with agricultural relevance. The peptides were an analog of Temporin called Temporizina, a fragment from Pleurocidin termed Plc-2, and a peptide identified from sesame seeds named Pses3. Antimicrobial activity of these peptides towards filamentous fungi has not been previously reported. Seven plant pathogenic or mycotoxigenic fungal species, isolated from plant tissues were assayed: Alternaria solani, Colletotrichum gloesporioides, Fulvia fulvum, Fusarium oxisporum, Aspergillus niger, A.
ochraceus and Penicillium digitatum. Values of Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) were determined and compared with the commercially available fungicide Captan as a positive control. The peptides showing greatest inhibition were Pses3 and Plc-2 and C.
gloesporioides was the most sensitive of the evaluated fungi. The MIC values for Plc-2 and Pses3 peptides ranged from 0.64 µM to 10.25 µM. These values were much lower than those observed for Captan, suggesting the potential of these peptides as fungicides. In particular, Pses3 is a novel peptide derived from sesame seeds not reported in databases. |

Abstract:
The goal of our study was to improve Tannat grape and wine composition by achieving vine balance in high-capacity conditions. The current Uruguayan grape-growing paradigm accepts unpredictable periods of water deficit or excess in non-irrigated vineyards, only applying herbicides to eliminate weed competition (H). We used an under-trellis cover crop (UTCC) to limit vine water availability and to reduce vine growth rate and final canopy size. However, to avoid excessive vine water stress due to UTCC competition, irrigation was used as needed during water deficit periods. The experiment was conducted over three consecutive growing seasons from 2011 to 2013, in two experimental vineyards located in southern Uruguay (34°?S 56°?W). Treatments were: UTCC (full cover of the vineyard soil with tall fescue) versus conventional alleyway tall fescue with a 1.0?m-wide weed-free strip under the trellis. Deficit drip irrigation was provided at mid-day stem water potential (SWP) thresholds of ?0.9?MPa early in the season and ?1.1?MPa later. Shoot growth rate, SWP, berry size and berry composition (Brix, organic acids, total anthocyanins) were monitored over the season as well as final yield, cluster and pruning weights and wine sensory attributes. UTCC regulated vine vegetative growth and final canopy size and reduced bunch rot incidence as well as increasing fruit Brix and anthocyanin concentration in grapes and wines. Wines from UTCC treatments had an increased fruity aroma and overall aroma intensity levels and had distinctive sensory characteristics that exceeded those of H wines during overall palatability tests (liking tests).
