Abstract
Summary The effects of different types of stress on RNA and protein synthesis have been studied in embryonic axes of seeds of chick-pea ( Cicer arietinum L.) during the first hours of germination as well as their relationship with the effects produced by exogenous application of abscisic acid (ABA) on this process. Stress induced by high (30 °C) and low (8 °C) temperatures, drought and high salinity reduced the incorporation of 3 H-Uridine and 14 C-leucine in embryonic axes and also modified their mRNA populations. Some of the polypeptides induced by these treatments were coincident with those specifically regulated by ABA, suggesting the participation of a common mechanism in some of the responses to ABA and to the different conditions of stress studied.
