1. Expressão fenotípica e mecanismos de ação de genes envolvidos na resistência ampla e begomovírus monopartidos e bipartidos em tomate
O tomateiro é uma das hortaliças mais importantes no Brasil tanto em área cultivada como pela importância sócio-econômica, entretanto o seu cultivo no país e no mundo tem sido severamente afetado por espécies de Begomovirus (família Geminiviridae). Estes vírus são transmitidos eficientemente pela mosca-branca (Bemisia tabaci), importante insetopra

2. Busca por Tomato yellow leaf curl virus e Tomato yellow leaf curl Sardinia virus em tomateiros
A doença causada pelo complexo de vírus do tomato yellow leaf curl (TYLC) é muito séria em tomateiro, principalmente na América Central e Europa, e é causada por um complexo de begomovírus monopartidos. A doença torna-se predominante, mesmo em áreas com a presença de outros begomovírus. No Brasil, os problemas advindos da infecção por begomovír

3. Transgenically Expressed T-Rep of Tomato Yellow Leaf Curl Sardinia Virus Acts as a trans-Dominant-Negative Mutant, Inhibiting Viral Transcription and Replication
We have previously shown that transgenic expression of a truncated C1 gene of Tomato yellow leaf curl Sardinia virus (TYLCSV), expressing the first 210 amino acids of the replication-associated protein (T-Rep) and potentially coexpressing the C4 protein, confers resistance to the homologous virus in Nicotiana benthamiana plants. In the present study we have

4. Tête à Tête of Tomato Yellow Leaf Curl Virus and Tomato Yellow Leaf Curl Sardinia Virus in Single Nuclei
Since 1997 two distinct geminivirus species, Tomato yellow leaf curl Sardinia virus (TYLCSV) and Tomato yellow leaf curl virus (TYLCV), have caused a similar yellow leaf curl disease in tomato, coexisted in the fields of southern Spain, and very frequently doubly infected single plants. Tomatoes as well as experimental test plants (e.g., Nicotiana benthamian

5. Tomato Yellow Leaf Curl Sardinia Virus Rep-Derived Resistance to Homologous and Heterologous Geminiviruses Occurs by Different Mechanisms and Is Overcome if Virus-Mediated Transgene Silencing Is Activated
The replication-associated protein (Rep) of geminiviruses is involved in several biological processes brought about by the presence of distinct functional domains. Recently, we have exploited the multifunctional character of the Tomato yellow leaf curl Sardinia virus (TYLCSV) Rep to develop a molecular interference strategy to impair TYLCSV infection. We sho

6. Interaction between a Geminivirus Replication Protein and the Plant Sumoylation System
Geminiviruses are small DNA viruses that replicate in nuclei of infected plant cells after accumulation of host replication machinery. Tomato golden mosaic virus (TGMV) and Tomato yellow leaf curl Sardinia virus (TYLCSV) encode a protein, RepAC1 (or Rep), that is essential for viral replication. Rep/RepAC1 is an oligomeric protein that binds to double-strand
