ЗАВИСИМОСТЬ ЭКСПРЕССИИ ГЕНОВ, КОНТРОЛИРУЮЩИХ ФУНКЦИОНИРОВАНИЕ БРАССИНОСТЕРОИДОВ И ЭТИЛЕНА В КЛЕТКАХ РАСТЕНИЙ ТОМАТА, ОТ ГРАВИСТИМУЛЯЦИИ ИХ ВЕРХУШЕЧНЫХ ЛИСТЬЕВ

Abstract

The influence of gravistimulation on the gene expression level in tomato leaf cells at early (15 minutes – 3 hours) and late (more than 3 hours – 24 hours) stages of the gravitropic response was assessed. The sensitivity of expression of genes coding proteins associated with brassinosteroid and ethylene functioning was determined using real-time RT-PCR. The pre-treatment of tomato plants with ethephon (the source of exogenous ethylene) led to an increase in the relative level of expression of the investigated genes under gravistimulation in the plants.
