Estruturas do tipo mycoplasma no floema de tomateiro afetado pelo cálice gigante

Abstract: Lycopersicon esculentum Mill.), denominada cálice gigante ou superbrotamento, é de ocorrência esporádica no Estado de S. Paulo. Ela é transmissível por enxertia e pela Cuscuta, tendo sido apontada sua similaridade com o vírus do "big bud" (2). Há evidências de que o cálice gigante do tomateiro e o superbrotamento de Erigeron bonariensis L. têm o mesmo agente causai (3). Recentemente, estruturas do tipo mycoplasma têm sido associadas ao "stolbur" europeu (4-5), que é considerado como sendo relacionado ao "big b… Show more

“…Phytoplasmas have been associated to several economic crops, weeds and wild species in Brazil (Kitajima, 1994). Tomato big bud is a disease known since the 1940s in Brazil, but its causal agent was identified as a phytoplasma only at the end of the 1960s (Costa, 1949; Kitajima and Costa, 1968). Recently, a phytoplasma belonging to group 16SrIII was identified from tomato plants with symptoms of big bud by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) analyses (Amaral Mello et al., 2003).…”

“…No Brasil, na década de 60, fitoplasmas foram associados a plantas de tomate exibindo sintomas de superbrotamento de ramos, enfezamento, clorose, redução no tamanho de folhas e cálice gigante (14,23). Trinta anos depois, no Distrito Federal, fitoplasmas foram detectados em plantas de berinjela exibindo os mesmos sintomas (5).…”
