Prolonged infection of tomato hybrid (Lycopersicon esculentum×Lycopersicon peruvianum) by Citrus exocortis viroid (CEVd) resulted in viroid-like enlarged structures, detected by gel electrophoresis. This population included two new enlarged variants or D-variants, D-87 and D-76, and three transient species or D-forms, D-38, D-40 and D-43. Sequence analyses exposed a locus near the terminal repeat region where major changes appeared consistently. In transmission tests to CEVd hosts, a variety of progeny populations were recovered, including progeny enlargements of and reversions to CEVd, as well as sequence fidelity to the inoculum. Transmission tests to citrus hosts of the genera Citrus, Poncirus or Fortunella were unsuccessful. The importance of host specificity to the recovery and processing of the various CEVd-related structures, as well as the temporal variability of progeny populations, was demonstrated.

Septoria Lycopersici

A transferência de genes da espécie silvestre Lycopersicon peruvianum para a espécie L. esculentum por processo convencional de hibridação é limitada por incompatibilidade. O objetivo deste trabalho foi desenvolver um método de obtenção de híbridos entre essas duas espécies, mediante a técnica de cultura de óvulos, tendo em vista o interesse em transferir genes presentes em acessos de L. peruvianum que conferem resistência a Septoria lycopersici. Foram utilizados os acessos CNPH 946, CNPH 947 e CNPH 948 de L. peruvianum e as cultivares Floradade e Ipa-5 de L. esculentum. Sementes híbridas de frutos com 25-68 dias após a polinização foram colocadas para germinar inicialmente em meio de cultura Murashige & Skoog (MS), e posteriormente em meio HLH. As sementes foram incubadas no escuro a 25°C. Só foram regenerados os híbridos provenientes das sementes colocadas para germinar em meio HLH. Dezesseis híbridos foram obtidos de 1.573 óvulos, sendo de 1% a taxa de regeneração de plantas híbridas. As características morfológicas dos híbridos F1 quando comparadas com os dois genitores indicaram que as plantas eram realmente resultado da hibridação entre L. esculentum e L. peruvianum.
