Abstract

Plant growth and development is strongly modulated by light, a phenomenon known as photomorphogenesis. For this, an intricate photoreceptor system acts on the perception and signaling of these responses, with recent highlights for events related to abiotic stresses. Although the evidence is clear, the interaction of the blue light, through the signaling of the cryptochromes, with the mechanisms of tolerance to the water deficit, is little known. Also, some reports clearly indicate the participation of cryptochrome 1 (cry1) in the regulation of drought stress. However, nothing is known about the functions of this photoreceptor in the responses to water deficit in tomato, especially in relation to root/shoot signaling. Thus, some questions can be raised: is cryptochrome 1 an important molecule in the control of water deficit in tomato? If yes, does cryptochrome 1 act negatively or positively during the water deficit? Furthermore, the biochemical signal induced by that photoreceptor is sent from root to shoot by controlling the responses to drought? The essential vegetable tool to answer such questions, taking into account the high level of complexity of the subject, will be the tomato mutant in cryptochrome 1 (cry1) biosynthesis, as well as grafting combinations between this mutant and the control. Therefore, the objective of this project is to understand the role of cryptochrome 1 in the response to stress due to water deficit in tomato plants through the use of the cry1 mutant. (AU)
