Coffee is a very important product in the State of Espírito Santo, Brazil, and most of it is planted as unshaded coffee monocultures, with few growers managing shaded coffee agroforestry systems (AFS). To analyze the opportunities and challenges associated with coffee agroforestry management, we conducted 58 semistructured interviews with coffee growers. In addition, we conducted a field investigation that tested production of Coffea canephora with the shade trees Australian Cedar (Toona ciliata), Jequitibá (Cariniana legalis), and Teak (Tectona grandis). Of the 58 interviewed farmers, 64% (37) were satisfied with the AFS. One of the main factors that caused satisfaction was obtaining income from sources other than coffee. Unsatisfied farmers mentioned the competition between shade trees and coffee shrubs. Cedar was the shade tree that grew most and reduced coffee production, while the combination with Jequitibá maintained more stable yields. We conclude that the higher the growth rate of trees, the higher the negative impact on the coffee production in the study areas. |

Papaya sticky disease is caused by the association of a fusagra-like and an umbra-like virus, named papaya meleira virus (PMeV) and papaya meleira virus 2 (PMeV2), respectively. Both viral genomes are encapsidated in particles formed by the PMeV ORF1 product, which has the potential to encode a protein with 1563 amino acids (aa). However, the structural components of the viral capsid are unknown. To characterize the structural proteins of PMeV and PMeV2, virions were purified from Carica papaya latex. SDS-PAGE analysis of purified virus revealed two major proteins of ~40 kDa and ~55 kDa. Amino-terminal sequencing of the ~55 kDa protein and LC-MS/MS of purified virions indicated that this protein starts at aa 263 of the deduced ORF1 product as a result of either degradation or proteolytic processing. A yeast two-hybrid assay was used to identify Arabidopsis proteins interacting with two PMeV ORF1 product fragments (aa 321?670 and 961?1200). The 50S ribosomal protein L17 (AtRPL17) was identified as potentially associated with modulated translation-related proteins. In plant cells, AtRPL17 co-localized and interacted with the PMeV ORF1 fragments. These findings support the hypothesis that the interaction between PMeV/PMeV2 structural proteins and RPL17 is important for virus?host interactions. |
