Fusarium oxysporum f. sp. lycopersici (FOL) races 1 and 2 were, up to recent years, the only pathogenic Fusaria associated with tomatoes (Solanum lycopersicum L.) in Brazil. However, recent outbreaks of F. oxysporum isolates with the ability to breakdown the I?2-mediated resistance prompted us to conduct nationwide surveys of the pathogens associated with vascular wilt of tomatoes. During these surveys, eight atypical F. oxysporum isolates (collected across five tomato?producing Brazilian states) displayed a peculiar ability of infecting accessions carrying the I?3 and I?7 genes (controlling resistance to FOL race 3 isolates). These observations suggested the involvement of either a new FOL race or of F. oxysporum f. sp. radicis-lycopersici (FORL) isolates. Koch?s postulates were fulfilled for these eight atypical isolates via root dipping inoculation (106 conidia mL− 1) of seedlings from two tomato cultivars ?Ponderosa? and ?Dominador?. All eight isolates induced crown-rot symptoms only in ?Ponderosa?, but not in ?Dominador? (which is resistant to FORL). To confirm the FORL identity, PCR assays were done using a set of race-specific and forma specialis-specific primers. A single amplicon of ≈ 947 bp was observed with the primer pair Sprl only with DNA template obtained from standard FORL isolates and from the eight atypical isolates, confirming the first detection of this forma specialis in Brazil. The geographical distribution of FORL isolates across major tomato?producing areas may require the incorporation of resistant factors into adapted cultivars.

The production of black pepper seedlings through grafting is a promising strategy to mitigate the effect of environmental stresses, such as drought, that limit its cultivation. However, studies on compatibility between grafts and rootstocks are still scarce, especially considering the wild species of the genus Piperand the cultivated genotypes of black pepper. The objective of this work was to evaluate the relationshipbetween primary metabolism and the development of black pepper seedlings obtained through intra-and interspecific grafting. The method used was that of cleft lateral grafting, as graft the Bragantina cultivar, better known in the world as ?Panniyur 1?, and ?Kottanadan? cultivar and three wild species (Piper hispidum, Piper aduncum and Piper tuberculatum) were used as root-stock. As a control, ́Bragantina` was grafted onto itself (homograft). The experiment was carried out for 110 days and the seedlings were evaluated for development, gas exchange, and carbohydrate allocation. The rootstock influences the development and primary metabolism of seedlings. P. aduncum showed greater initial compatibility among wild species, due to less impediment to carbohydrate flow. P. tuberculatum showed early incompatibility, as the grafts died.The seedlings grafted on P. hispidumand 'Kottanadan' had initial compatibility with an average of 78% survival and 60% budding, but they may have late incompatibility due to limitation of carbohydrate flow.

No entanto, ainda são escassos os estudos de compatibilidade entre enxerto e porta-enxerto, principalmente considerando as espécies selvagens do gênero Pipere os genótipos cultivados de pimenteira-do-reino. Objetivou-se com este trabalho avaliar a relação entre o metabolismo primário e o desenvolvimento das mudas da pimenteira-do-reino obtidas através da enxertia intra e interespecífica. O método empregado foi o de enxertia lateral em fenda cheia, como enxerto foi utilizada a cultivar Bragantina, mais conhecida no mundo como ?Panniyur 1? e como porta-enxerto foram avaliados a cultivar ?Kottanadan? e três espécies selvagens (Piper hispidum, Piper aduncum e Piper tuberculatum).Como controle foi efetuado a enxertia da Bragantina` nela mesma (homoenxerto). O experimento foi conduzido durante 110 dias e as mudas foram avaliadas quanto ao desenvolvimento, trocas gasosas e alocação de carboidratos. O porta-enxerto influencia no desenvolvimento e nometabolismo primário das mudas. O porta-enxerto influencia no desenvolvimento e no metabolismo primário das mudas. P. aduncum apresentou maior compatibilidade inicial entre as selvagens, devido ao menor impedimento ao fluxo de carboidratos. P. tuberculatumapresentou incompatibilidade precoce, pois houveamorte dos enxertos. As mudas enxertadas em P. hispidume a ́Kottanadan` tiveram compatibilidade inicial apresentando em média 78% de sobrevivência e 60% de brotamento, porém podem ter incompatibilidade tardia por limitação ao fluxo de carboidratos.
