Overview

Experiments show drought and virus infection impact plant traits and aphid feeding behavior, suggesting complex interactions.

Key Points

  • Drought and virus infection significantly reduced plant dry weight, number of leaves, and leaf area.
  • Moderate water stress decreased the transmission rate of the persistent virus CABYV, while severe drought did not affect CMV inoculation.
  • Observations indicated that drought altered aphid feeding behavior, impacting its effectiveness in transmitting specific viruses.
  • Despite plant phenotype changes due to drought, the combination of drought and virus infection did not significantly affect aphid feeding related to virus transmission.
