Cross talk between signal transduction pathways
Gazzarrini and McCourt (605-612) review a subset of genes in arabidopsis that influence hormonal cross-talk with emphasis on GA, ABA and ethylene pathways. Hormones appear to interact with each other and with a variety of developmental and metabolic signals. It also appears that the actions of various hormones may converge to regulate the turnover of important regulators involved in growth and development.
