The aerial parts of plants are protected from desiccation and other stress by surface cuticular waxes. The total cuticular wax loads and the expression of wax biosynthetic genes are significantly downregulated in Arabidopsis thaliana under dark conditions. We isolated Decrease Wax Biosynthesis (DEWAX), which encodes an AP2/ERF-type transcription factor that is preferentially expressed in the epidermis and induced by darkness. Disruption of DEWAX leads to an increase in total leaf and stem wax lo ...[more]
Project description:Wild Type and OsTZF1-OX plants were grown in soil in isolation green house for 2 weeks under flooded lowland conditions and a 12 h/12 h light/dark cycle (1000 umol photons/m2/s) at 28C (day) and 25C (night).
Project description:Vector control and OsTZF1-OX rice plants (O. sativa L. cv. Nipponbare) were grown in plastic pots filled with nutrient soil for 2 weeks under flooded lowland conditions and a 12 h/12 h light/dark cycle (1000 umol photons/m2/s) at 28C (day) and 25C (night). For NaCl treatment, two-week-old plants were transferred to 250 mM NaCl solution and incubated for 2 days under the above conditions.
Project description:In order to study possible effects of cryptochrome 2-mediated light signals on the global expression profiles of tomato genes, we performed large scale transcription comparisons in wt and CRY2-OX by using a DNA microarray of more than 90,000 tomato oligo-probes.<br>Tomato plants were grown under a daily light cycle of 16h light/8h darkness (LD) and leaves from both genotypes were sampled at presumptive dawn (Zeitgeber time (ZT) 0), eight hours after dawn (ZT8), at presumptive dusk (ZT16) and four hours after dusk (ZT20).
