Avaliou-se o efeito de doses e fontes de fósforo na produção de alface americana em experimento no município de Santo Antônio do Amparao, MG, de junho a setembra/98. O delineamento utilizado foi blocos ao acaso em esquema fatorial 2x4, com três repetições, compreendendo duas fontes de fósforo [superfosfato simples (18% de P2O5) e termofosfato magnesiano (17% de P2O5)] , e quatro doses (0, 300, 600, 900 kg ha-1 de P2O5). Avaliou-se a produção total e comercial de alface, comprimento e caule e circunferência da cabeça comercial. Observou-se para a produção total e comercial efeitos significativos na interação entre doses e fontes. Para o superfosfato simples houve regressão quadrática em que as doses de 672 e 617 kg ha-1 de P2O5, apresentaram as maiores produções total e comercial, respectivamente. Quanto ao termofosfato magnesiano verificou-se aumento linear na produtividade. Com o uso da dose de 583 kg ha-1 de P2O5, obteve-se o maior comprimento de caule (6,7 cm), sem no entanto, prjudicar o valor comercial. As doses, bem como as fontes de fósforo utilizadas não apresentaram o efeito significativo com relação à circunferência da cabeça comercial. |

Brevipalpus-transmitted viruses (BTVs) belong to the genera Dichorhavirus and Cilevirus and are the main causal agents of the citrus leprosis (CL) disease. In this report, we explored aspects related to the movement mechanism mediated by dichorhaviruses movement proteins (MPs) and the homologous and heterologous interactions among viral proteins related to the movement of citrus leprosis-associated viruses. The membrane-spanning property and topology analysis of the nucleocapsid (N) and MP proteins from two dichorhaviruses revealed that the MPs are proteins tightly associated with the cell membrane, exposing their N- and C-termini to the cytoplasm and the inner part of the nucleus, whereas the N proteins are not membrane-associated. Subcellular localization analysis revealed the presence of dichorhavirus MPs at the cell surface and in the nucleus, while the phosphoproteins (P) were located exclusively in the nucleus and the N proteins in both the cytoplasm and the nucleus. Co-expression analysis with the MP, P, and N proteins showed an interaction network formed between them. We highlight the MP capability to partially redistribute the previously reported N-P core complex, redirecting a portion of the N from the nucleus to the plasmodesmata at the cell periphery, which indicates not only that the MP might guide the intracellular trafficking of the viral infective complex but also that the N protein may be associated with the cell-to-cell movement mechanism of dichorhaviruses. The movement functionality of these MPs was analyzed by using three movement-defective infectious systems. Also, the MP capacity to generate tubular structures on the protoplast surface by ectopic expression was analyzed. Finally, we evaluated the in vivo protein?protein interaction networks between the dichorhavirus MP and/or N proteins with the heterologous cilevirus movement components, which suggest a broad spectrum of interactions, highlighting those among capsid proteins (CP), MPs, and Ns from citrus leprosis-associated viruses. These data may aid in understanding the mixed infection process naturally observed in the field caused by distinct BTVs.
