Project description:This transcriptomics analysis was undertaken to elucidate the effect of acetic acid stress in the reprogramming of C. glabrata KUE100 genomic expression. For this cells were cultivated in MM growth medium (at pH 4) either or not supplemented with a sub-lethal inhibitory concentration of acetic acid (30 mM). Furthermore it was also examined the response to the same concentration of acetic acid of a mutant devoid of the CgHaa1 transcription factor

Project description:Genes whose expression correlated to the acetic acid tolerance in S. cerevisiae were identified by DNA microarray analysis. Gene expression profiles of two S. cerevisiae strains showing different levels of acetic acid tolerance were compared and an acetic acid tolerance-related gene chosen.

Project description:Transcript profiling was performed using a wild-type C. albicans strain (CaI8+CIp10). Cells were cultured in 50 ml SC-pH3.0 to a cell density of 1x10^7 cells per ml and then either treated with control (0 mM acetic acid) or stress inducing (20 mM acetic acid) doses. Cells from the same culture were harvested after 300 min treatment. Three independent biological replicates were obtained for each condition.

Project description:External application of acetic acid has been recently reported to enhance the survival to drought in plants such as Arabidopsis, rapeseed, maize, rice and wheat, but the effects of acetic acid application on increased drought tolerance in woody plants such as a tropical crop “cassava” remain elusive. A molecular understanding of acetic acid-induced drought avoidance in cassava will contribute to the development of technology that can be used to enhance drought tolerance without resorting to transgenic technology or advancements in cassava cultivation. In the present study, morphological, physiological and molecular responses to drought were analyzed in cassava after the treatment with acetic acid. Results indicated that the acetic acid-treated cassava plants had a higher level of drought avoidance than water-treated, control plants. Specifically, higher leaf relative water content, and chlorophyll and carotenoid levels were observed as soils dried out during the drought treatment. Leaf temperatures in acetic acid-treated cassava plants were higher relative to leaves on plants pretreated with water and the increase of ABA content was observed in leaves of acetic acid-treated plants, suggesting that stomatal conductance and the transpiration rate in leaves of acetic acid-treated plants decreased to maintain relative water contents and avoid drought. Transcriptome analysis revealed that the acetic acid treatment increased the expression of ABA signaling-related genes, such as OPEN STOMATA 1 (OST1) and protein phosphatase 2C; as well as drought response and tolerance-related genes, such as outer membrane tryptophan-rich sensory protein (TSPO), and heat shock proteins. Collectively, the external application of acetic acid enhances drought avoidance in cassava through the upregulation of ABA signaling pathway genes and several stress response- and tolerance-related genes. These data support the idea that adjustments of the acetic acid application to plants is useful to enhance drought tolerance in order to minimize the growth inhibition in the agricultural field.

Project description:This study investigated the responses of ZM532 and wild-type ZM4 to acetic acid and furfural using genomics, transcriptomics and label free quantitative proteome. By Sanger sequencing technology we re-verified of previously identified 19 mutations in ZM532, but we found a total of 23 single nucleotide polymorphisms (SNPs) in the coding sequence (CDS; 4) and intergenic region (19) in ZM532. Six SNPs were however novel in this study. We also identified a total of 1865 and 14 novel differentially expressed genes (DEGs) in ZM532 and wild-type ZM4. Further we identified 1,532 proteins by label free proteome. These proteins and genes are involved in amino acid biosynthesis, macromolecules repair, glycolysis, flagella assembly, ABC transporter, fermentation, and ATP synthesis pathways and stress response. The exclusively found genes and proteins in ZM532 confirmed and help to unravel the acetic acid and furfural tolerance mechanism between ZM532 and wild-type ZM4. May be these proteins and genes play key roles in ZM532 regulation with strong expressions under acids stress conditions. Furthermore, we knocked-out and overexpressed two differentially expressed genes (DEGs), ZMO_RS02740 up-regulated and ZMO_RS06525 down-regulated to investigate their roles in acetic acid and furfural tolerance. Our knockout and complementary experiments revealed that up-regulated expression gene ZMO RS02740 and the down-regulated expression gene ZMO-RS06525 play important roles in dealing with Furfural and acetic acid stress. ZM532 can be used to substitute ZM4 as a biocatalyst for bioethanol under acetic acid and furfural condition, with a shorter fermentation time and higher productivity.
