The gene was isolated as a heat-sensitive mutant, but the function of the protein remained unclear. We examined the expression pattern and subcellular localization of C09F5.1 as well as its roles in thermotolerance and chaperone function. Expression of C09F5.1 under heat shock conditions was induced in a heat shock factor 1 (HSF-1)–dependent manner. However, under normal growth conditions, most cells types exposed to mechanical stimuli expressed C09F5.1. Knockdown of C09F5.1 expression or deletion of the N-terminal domain decreased thermotolerance. -
Modified Bradford Assay Method of Protein Quantification Utilising Dye Reagents from Four Nigerian Plants
International Journal of Research Studies in Biosciences (IJRSB) Volume 3, Issue 12, December 2015, PP 79-87 ISSN 2349-0357 (Print) & ISSN 2349-0365 (Online) www.arcjournals.org Modified Bradford Assay Method of Protein Quantification Utilising Dye Reagents from Four Nigerian Plants *S.

Lori *Department.of Chemistry, Nigerian Defence Academy, Afaka, Kaduna State - Nigeria ** Department of Chemical & Physical Sciences, Walter Sisulu University Eastern Cape, South Africa ***Department of Chemistry, Bingham University, Karu, Nassarawa State - Nigeria Abstract: Aqueous and organic solvents extraction process using ethanol, methanol and chloroform were carried out with four different Nigerian plants namely: Pterocarpus osun (uhe), Lawsonia inermis (lalle), Bixa Orellana (annatto) and Hibiscus sabderriffa (zobo) to extract dye reagents from the plants. The ability of the dye reagents to replace Coomassie Brilliant Blue in the Bradford assay method of protein quantification were determined and compared. The solvents extracts gave good colourful results in the extraction of the dye reagents while only aqueous extract of Hisbiscus sabderiffa (zobo) gave similar results to that of solvent extracts. The solvent extracts obtained from Pterocarpus osun (uhe), Lawsonia inermis (lalle) and Bixa Orellana (annatto) plants could not be used to estimate amino acids from protein samples. However, solvent extracts of Hibiscus sabderriffa (zobo) was able to estimate amino acids from protein samples. The change in maximum wavelength (λmax) and the increased absorption with zobo dye reagent; on addition of protein samples showed that solvent extract of Hibiscus sabderiffa (zobo) dye has the potential to quantify and estimate amino acids in protein samples as much as the Coomassie Blue utilised in the Bradford assay method. -

NONLINEAR LASER WAVE-MIXING DETECTION FOR CAPILLARY ELECTROPHORESIS AND MULTI-CHANNEL ARRAYS FOR BIOMEDICAL AND ENVIRONMENTAL APPLICATIONS _______________ A Thesis Presented to the Faculty of San Diego State University _______________ In Partial Fulfillment of the Requirements for the Degree Master of Science in Chemistry _______________ by Eric J. Maxwell Spring 2015 iii Copyright © 2015 by Eric J. Maxwell All Rights Reserved iv DEDICATION To my wife, Selena, for supporting me through all of the long nights and weekends of work that this program required. I cannot wait to start the next chapter in this journey. v ABSTRACT OF THE THESIS Nonlinear Laser Wave-Mixing Detection for Capillary Electrophoresis and Multi-Channel Arrays for Biomedical and Environmental Applications by Eric J. Maxwell Master of Science in Chemistry San Diego State University, 2015 Degenerate Four-Wave Mixing is demonstrated as a highly sensitive nonlinear spectroscopic detection method for biomedical and environmental targets. This is achieved through refractive index change within an absorbing liquid medium, which produces a laser- like signal beam. This signal has high spatial resolution, and may be collected with high efficiency against a nearly 100% dark background. The cubic dependence on laser power and square dependence on analyte concentration allow for high signal intensity in trace analysis applications. In this work, the Degenerate Four-Wave Mixing technique is coupled with capillary electrophoresis, immunoprecipitation or color-forming reactions to provide specificity. The veterinary drugs malachite green and crystal violet are shown to be detectable at concentrations as low as 6.9 x 10-10 M (2.5 x 10-19 mol) and 8.3 x 10-11 M (3.0 x 10-20 mol) respectively (S/N = 2). -

A Tool to Detect Cis-Acting Elements Near Promoter Regions in Rice
Planta (2021) 253:40 https://doi.org/10.1007/s00425-021-03572-w ORIGINAL ARTICLE Rice protein‑binding microarrays: a tool to detect cis‑acting elements near promoter regions in rice Joung Sug Kim1 · SongHwa Chae1 · Kyong Mi Jun2 · Gang‑Seob Lee3 · Jong‑Seong Jeon4 · Kyung Do Kim1 · Yeon‑Ki Kim1 Received: 27 October 2020 / Accepted: 8 January 2021 / Published online: 21 January 2021 © The Author(s) 2021 Abstract Main conclusion The present study showed that a rice (Oryza sativa)-specifc protein-binding microarray (RPBM) can be applied to analyze DNA-binding motifs with a TF where binding is evaluated in extended natural promoter regions. The analysis may facilitate identifying TFs and their downstream genes and constructing gene networks through cis-elements. Abstract Transcription factors (TFs) regulate gene expression at the transcriptional level by binding a specifc DNA sequence. Thus, predicting the DNA-binding motifs of TFs is one of the most important areas in the functional analysis of TFs in the postgenomic era. Although many methods have been developed to address this challenge, many TFs still have unknown DNA- binding motifs. In this study, we designed RPBM with 40-bp probes and 20-bp of overlap, yielding 49 probes spanning the 1-kb upstream region before the translation start site of each gene in the entire genome. To confrm the efciency of RPBM technology, we selected two previously studied TFs, OsWOX13 and OsSMF1, and an uncharacterized TF, OsWRKY34. We identifed the ATT GAT TG and CCA CGT CA DNA-binding sequences of OsWOX13 and OsSMF1, respectively. In total, 635 and 932 putative feature genes were identifed for OsWOX13 and OsSMF1, respectively. -
