Trehalose increases tomato drought tolerance, induces defenses, and increases resistance to bacterial wilt disease

A. M. MacIntyre, V. Meline, Z. Gorman, S. P. Augustine, C. J. Dye, C. D. Hamilton, A. S. Iyer-Pascuzzi, M. V. Kolomiets, K. A. McCulloh, C. Allen

This study shows that exogenous trehalose improves tomato drought tolerance and bacterial wilt resistance by enhancing ABA and SA signaling, and triggering systemic disease resistance.

Image-based assessment of plant disease progression identifies new genetic loci for resistance

V. Meline, D. Caldwell, B.-S. S. Kim, S. Baireddy, C. Yang, E. E. Sparks, E. J. Delp, A. S. Iyer-Pascuzzi

The paper uses image-based phenotyping to identify new genetic loci for disease resistance in tomato plants, detecting QTL earlier and more accurately than human assessment.
