Total proteome of germinative and dormant axillary buds of the sugarcane cultivar RB867515

ABSTRACT: Sugarcane is the raw material for the production of ethanol and sugar, and its by-products are used in cogeneration of energy in addition to various industrial processes. The cane field establishment is dependent of the axillary buds sprouting. The present study aimed to catalog the total proteome of germinative axillary bud and dormant axillary buds, and to identify important budding proteins, which are differentially expressed in these types of axillary buds. The proteome was obtained by extraction of total proteins using the TCA acetone method adapted for axillary buds. The experiment was carried out in biological triplicate. Protein samples were submitted to denaturing polyacrylamide gel electrophoresis (SDS-PAGE) and stained with comassie blue. Each lane of the polyacrylamide gel was fractionated (11 slice) and treated for purification and isolation of the polypeptides. Tryptic digestion was performed on each fragment with subsequent UPLC separation (Nano Acquity). The polypeptides were analyzed on Waters® Micromass® ESI-Q-Tof micro ™ mass spectrometer. Protein samples from the germinative and dormant axillary buds showed distinct bands patterns in the SDS-PAGE gel. Mass spectrometry data were analyzed by MASCOT tool (http://www.matrixscience.com).

TOTAL AND DIFFERENTIAL PROTEOME OF AXILLARY BUDS OF SUGARCANE CULTIVAR RB867515 IN DIFFERENT CUTS

Project description:The objective of this work was to know the effect of sugarcane cultivation on protein expression during the sugarcane cutting cycles, characterizing the total and differential proteome of axillary buds of the plant cane and fourth ratoon of the cultivar RB867515. The total proteins were extracted in triplicate by the modified TCA/acetone method for use in axillary sugarcane buds. Protein samples were submitted to denaturing polyacrylamide gel electrophoresis (SDS-PAGE) and stained with comassie blue. Each lane of the polyacrylamide gel was fractionated (11 slice) and treated for purification and isolation of the polypeptides. Tryptic digestion was performed on each fragment with subsequent UPLC separation (Nano Acquity). The polypeptides were analyzed on Waters® Micromass® ESI-Q-Tof micro ™ mass spectrometer. Protein samples from the axillary buds at different cut stages showed distinct bands patterns in the SDS-PAGE gel. Mass spectrometry data were analyzed by MASCOT tool (http://www.matrixscience.com).

Short RNAs associated to Cauliflower mosaic virus infections in Canola and Turnip

Project description:Three plants of two species in Brassica genus, i.e. B. rapa cv. "Purple To White Globe" and B. napus cv. "SariGol", highly susceptible and tolerant hosts of Cauliflower mosaic virus (CaMV), respectively, were mechanically inoculated with CaMV strain NY8153.Phosphate buffer was used as control in mock-inoculated plants. RNAs, in three biological repeats, were extracted 20 days post-inoculation (dpi) collecting ten leaves from mock-inoculated and virus-infected plants using Trizol reagent (Invitrogen, Carlsbad, CA) according to the manufacturer’s instructions. Five µg of total RNA were resolved in 15% SDS-PAGE gel. Total RNA pattern was visualized upon Ethidium Bromide staining and sRNAs in the size range of 20-30 nt were eluted from gel. sRNAs replicates were quantified and mixed in equal molarity. Libraries were obtained using NEXTflex Small RNA-Seq Kit v3 (Bio Scientific) according to manufacturer’s instructions. Libraries were eluted from a 6% non-denaturing PAGE. The quality of libraries was checked by BioPharma QC, and then, submitted for sequencing with a HiSeq 2500 Illumina platform.

Small RNA from S2 cell infected with FHV deltaB2 particle

Project description:S2 cells were infected with FHV deltaB2 particle and the S2 cells were harvested to isolate total RNA at 96 hpi. Small RNAs were separated on a denaturing 15% polyacrylamide gel. Ligation to adapters requires 5' monophosphate and 3' OH. Note: The base quality (.qual) file corresponding to the fasta format (.fna) file linked to Sample GSM306489 is unavailable.

Differential sRNA regulation in leaves and roots of sugarcane under water depletion

Project description:In order to increase our understanding on the epigenetic regulation in response to abiotic stresses in plants, sRNA regulation in sugarcane plants submitted to drought stress was analyzed. Deep sequencing analysis was carried out to identify the sRNA regulated in leaves and roots of sugarcane cultivars with different drought sensitivities. An enrichment of 22-nt sRNA species was observed in leaf libraries. The pool of sRNA selected allowed the analysis of different sRNA classes (miRNA and siRNA). Twenty eight and 36 families of conserved miRNA were identified in leaf and root libraries, respectively. Dynamic regulation of miRNA was observed and the expression profile of eight miRNA was verified in leaf samples by stem-loop qRT-PCR assay. Altered miRNA regulation was correlated with changes in mRNA levels of specific targets. 22-nt miRNA triggered siRNA-candidates production by cleavage of their targets in response to drought stress. Some genes of sRNA biogenesis were down-regulated in tolerant genotypes and up-regulated in sensitive in response to drought stress. Our analysis contributes to increase the knowledge on the roles of sRNA in epigenetic-regulatory pathways in sugarcane submitted to drought stress.

Small RNA fraction between 19 and 24 nt was isolated from 15% denaturing polyacrylamide gel and 15 micro gram was ligated to Solexa adaptors (Illumina) without de-phosphorylating and re-phosphorylating. The short RNAs were converted to DNA by RT-PCR following the Illumina protocol.

Sugarcane Expression Data from Stress Time Series

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 RNA from experimental sample and from its respective control sample (untreated plants) was used for hybridization to dual channel arrays. Two biological replicates were used for each experimental point. The quantification of each hybridization was submitted in two files, one for each slide side (technical replicates).
