Papaya meleira virus (PMeV) is the causal agent of papaya sticky disease, which is characterized by a spontaneous exudation of fluid and aqueous latex from the papaya fruit and leaves. The latex oxidizes after atmospheric exposure, resulting in a sticky feature on the fruit from which the name of the disease originates. PMeV is an isometric virus particle with a double-stranded RNA (dsRNA) genome of approximately 12 Kb. Unusual for a plant virus, PMeV particles are localized on and linked to the polymers present in the latex. The ability of the PMeV to inhabit such a hostile environment demonstrates an intriguing interaction of the virus with the papaya. A hypersensitivity response is triggered against PMeV infection, and there is a reduction in the proteolytic activity of papaya latex during sticky disease. In papaya leaf tissues, stress responsive proteins, mostly calreticulin and proteasome-related proteins, are up regulated and proteins related to metabolism are down-regulated. Additionally, PMeV modifies the transcription of several miRNAs involved in the modulation of genes related to the ubiquitin-proteasome system. Until now, no PMeV resistant papaya genotype has been identified and roguing is the only viral control strategy available. However, a single inoculation of papaya plants with PMeV dsRNA delayed the progress of viral infection. |

This work tested the use of a superabsorbent polymer (hydrogel) in a silvopastoral system with Brazilian-rosewood (Dalbergia nigra (Vell.) Allemão ex Benth.) in a degraded pasture area. The experimental site is part of the Bananal do Norte experimental farm, Cachoeiro de Itapemirim, EspÃrito Santo, Brazil. Over 480 seedlings were planted and submitted to the treatments: Dry hydrogel (DRY); Hydrated hydrogel around the root ball (HAR); Hydrated hydrogel mixed with soil (HMS); and water only (WAT). The design was in randomized blocks, with three repetitions. The tested variables were plant survival, height and root collar diameter until 672 days after planting, soil moisture at 93 days after planting and total biomass and leaf chemical analysis at 184 days after planting. Survival was positively influenced by the application of the hydrogel, but there was little or no effect regarding the application method. The hydrogel and its application techniques did not alter growth in height and root collar diameter. The polymer did not influence the development in biomass and nutritional content of the leaves, but did influence the biomass distribution. The use of the superabsorbent polymer was therefore not effective in accelerating plant growth and anticipating the stages in the implantation of the silvopastoral system.
Neste trabalho, foi testado o uso de um polÃmero superabsorvente (hidrogel) em sistema silvipastoril com jacarandá-da-bahia (Dalbergia nigra (Vell.) Allemão ex Benth.), em área de pastagem degradada. A área experimental faz parte da fazenda experimental Bananal do Norte, Cachoeiro de Itapemirim, EspÃrito Santo, Brasil. Mais de 480 mudas foram plantadas e submetidas aos tratamentos Hidrogel seco (DRY); Hidrogel hidratado ao redor do torrão (HAR); Hidrogel hidratado misturado com solo (HMS); e apenas água (WAT). O delineamento foi em blocos casualizado, com três repetições. As variáveis testadas foram sobrevivência da planta, altura e diâmetro do coleto, até 672 dias após o plantio, umidade do solo aos 93 dias após o plantio e biomassa total e análise quÃmica foliar aos 184 dias após o plantio. A sobrevivência foi positivamente influenciada pela aplicação do hidrogel, mas pouca ou nenhuma diferença foi observada para os métodos de aplicação. O hidrogel e suas técnicas de aplicação não afetaram o crescimento em altura e diâmetro do coleto. O polÃmero não influenciou o desenvolvimento em biomassa e conteúdo nutricional das folhas, mas influenciou na distribuição de biomassa. Portanto, o uso do polÃmero superabsorvente não foi efetivo para acelerar o crescimento das plântulas e antecipar etapas na implantação de sistemas silvipastoris.
