    ..Thus, the spiralin could play a key role in the transmission of S. citri by mediating spiroplasma adherence to epithelial cells of insect vector gut or salivary gland. ..
  5. Killiny N, Almeida R. Host structural carbohydrate induces vector transmission of a bacterial plant pathogen. Proc Natl Acad Sci U S A. 2009;106:22416-20 pubmed publisher
    ..A better understanding of how vector-borne pathogens transition from host to vector, and vice versa, may lead to previously undiscovered disease-control strategies. ..
  6. Killiny N, Prado S, Almeida R. Chitin utilization by the insect-transmitted bacterium Xylella fastidiosa. Appl Environ Microbiol. 2010;76:6134-40 pubmed publisher
    ..In addition, chitin may trigger X. fastidiosa's gene regulation and biofilm formation within vectors. Further work is necessary to characterize the role of chitin and its utilization in X. fastidiosa. ..

    ..Exploring energy metabolic regulation in relation with adult survival might help in understanding the physiological basis of how ACP tolerates newly invaded regions. ..
  9. Killiny N, Jones S. Profiling of volatile organic compounds released from individual intact juvenile and mature citrus leaves. J Plant Physiol. 2017;208:47-51 pubmed publisher
    ..The finding that juvenile leaves emitted higher levels of sesquiterpenes while mature leaves released mostly monoterpenes suggests that younger leaves of plants may be involved in a more complex chemical communication system. ..
