Effect of gravistimulation on the level of gene expression controlling phospholipid, carbohydrate metabolism and transmembrane transport in tomato leaf cells at early (15 minutes–3 hours) and late (more than 3 hours–24 hours) expositions of gravitropic response was estimated. Sensitivity to gravistimulation of the PLC, PLDε, H-ATPase, Flipp, EXPА5, ß-Gluc and α-Gluc expression was determined using real-time RT-PCR. The pretreatment of plants with ethephon (the chemical analog of exogenous ethylene) and epibrassinolide (epin) led to a change in the relative level of expression of investigated genes in response to gravistimulation. |
