Among the most serious problems in papaya production are the viruses associated with papaya ringspot and papaya sticky disease (PSD). PSD concerns producers worldwide because its symptoms are extremely aggressive and appear only after flowering. As no resistant cultivar is available, several disease management strategies have been used in affected countries, such as the use of healthy seeds, exclusion of the pathogen, and roguing. In the 1990s, a dsRNA virus, papaya meleira virus (PMeV), was identified in Brazil as the causal agent of PSD. However, in 2016 a second virus, papaya meleira virus 2 (PMeV2), with an ssRNA genome, was also identified in PSD plants. Only PMeV is detected in asymptomatic plants, whereas all symptomatic plants contain both viral RNAs separately packaged in particles formed by the PMeV capsid protein. PSD also affects papaya plants in Mexico, Ecuador, and Australia. PMeV2-like viruses have been identified in the affected plants, but the partner virus(es) in these countries are still unknown. In Brazil, PMeV and PMeV2 reside in laticifers that promote spontaneous latex exudation, resulting in the affected papaya fruit?s sticky appearance. Genes modulated in plants affected by PSD include those involved in reactive oxygen species and salicylic acid signaling, proteasomal degradation, and photosynthesis, which are key plant defenses against PMeV complex infection. However, the complete activation of the defense response is impaired by the expression of negative effectors modulated by the virus. This review presents a summary of the current knowledge of the Carica papaya-PMeV complex interaction and management strategies.

Dois ciclos de selecao entre e dentro de familias de meios-irmaos foram efetuados na populacao de milho EEL, nas regioes Norte, Sul e Serrana do Estado do Espirito Santo, no periodo de 1987 a 1989. Em cada ciclo, duzentas progenies de meios-irmaos foram avaliadas, usando dois latices 10 x 10 com duas repeticoes por local. Aplicaram-se os indices de 15% de selecao entre as progenies, e 12,5% entre as progenies na recombinacao. Em relacao ao carater peso de espigas, as analises de variancia individuais e conjuntas detectaram deiferencas significativas para progenies e para a interacao progenies x locais. As variancias geneticas aditivas variaram entre locais e ciclos com valores entre 501,4 e 1002,7 (g/planta). Os valores dessas variancias nas analisesconjuntas foram inferiores aos das analises individuais, sendo de 58,0 e 292,7 (g/planta) no 1 e 2 ciclo, respectivamente. O ganho genetico medio esperado com a selecao do primeiro e segundo ciclo foi de 1,5% e 8,2%, respectivamente. As magnitudes destas estimativas, os altos valores de herdabilidade e dos coeficientes de variacoes geneticas, associados a altas medias de produtividade das progenies, sao indicadores do grande potencial desta populacao em um programa de melhoramento. |
