Physiological and Proteomic Investigations to Study the Response of Tomato Graft Unions under Temperature Stress.

ABSTRACT:

Background

Grafting is an established practice for asexual propagation in horticultural and agricultural crops. The study on graft unions has become of interest for horticulturists using proteomic and genomic techniques to observe transfer of genetic material and signal transduction pathways from root to shoot and shoot to root. Another reason to study the graft unions was potentially to observe resistance against abiotic stresses. Using physiological and proteomic analyses, we investigated graft unions (rootstock and scions) of tomato genotypes exposed to standard-normal (23/23 and 25/18°C day/night) and high-low temperatures (30/15°C day/night).

Results

Graft unions had varied responses to the diverse temperatures. High-low temperature, but not standard-normal temperature,
