Project description:Sugarcane (Saccharum hybrid, SP80-3280) was grown in the field in Araras (Brazil) for 9 months. Leaves +1 (F1), internodes 1&2 (I1), and internodes 5 (I5) were harvested every 2 h for 26 h, starting 2h before dawn.
Project description:The present work aimed to compare the transcriptome of three major ethanol-producer Saccharomyces cerevisiae strains in Brazil when fermenting sugarcane juice for fuel ethanol production. This was motivated by the reports presenting physiological and genomics differences among them, and by the attempt to identify genes that could be related to their fermentation capacity and adaptation for different industrial processes.

Two-condition experiment, T0h vs. T6h fermetations assay. Biological replicates: 3 T0h replicates, 5 T6h replicates.
Project description:Sugarcane one-eyed seed sets obtained from a variety sensitive to drought conditions (cv. SP90-1638, CTC, Brazil) were cultivated on moist sand for 15 days. The plants were transferred to pots containing moist sand and were irrigated with Hoagland’s solution (Hoagland and Arnon, 1950). Regular watering was maintained for 90 days and suppressed after this period for the experimental group. Leaves were collected 24 h, 72 h and 120 h after exposure to drought conditions for the control and experimental groups. Samples were collected and immediately frozen in liquid nitrogen. Leaves from six plantlets were used for each time point. Extraction of total RNA was performed separately on each sample pool. Keywords: time course of stress response
Project description:Sugarcane stalk borer larvae were grown on artificial diet and maintained at 25°C and 60±10% relative humidity with a 14 h/10 h light/dark cycle. Second instar larvae were maintained under fasting conditions for 18 h and transferred to two-month old plants (genotype SP80-3280, CTC, Brazil). Leaves were collected after 30 min and 24 h of exposure to herbivory for the control and experimental groups. Two plantlets were used for each time point. Extraction of total RNA was performed separately on each sample pool. Keywords: time course of stress response
Project description:Sugarcane one-eyed seed sets (genotype SP80-3280, CTC, Brazil) were planted in 200 ml plastic cups containing a commercial planting mix (Plantmax, Eucatex) and cultivated for 20 days under greenhouse conditions. The plantlets were subsequently transferred to a growth chamber at 26°C on a 16 h/8 h light/dark cycle with a photon flux density of 70 µE.m-2.s-1 to acclimate. Plantlets were then sprayed with a 100 µmol.L-1 MeJA solution (Bedoukian Research Inc., Danbury, CT), whereas control plantlets were treated with distilled water. Leaves were collected 0, 1, 6and 12 h after exposure to MeJA and immediately frozen in liquid nitrogen. Six plantlets were used for each time point. Extraction of total RNA was performed separately on each sample pool. Keywords: time course of hormone treatment
