  • Association of Variation in the Sugarcane Transcriptome with Sugar Content Prathima P
    Thirugnanasambandam et al. BMC Genomics (2017) 18:909 DOI 10.1186/s12864-017-4302-5 RESEARCH ARTICLE Open Access Association of variation in the sugarcane transcriptome with sugar content Prathima P. Thirugnanasambandam1,2†, Nam V. Hoang1,3†, Agnelo Furtado1, Frederick C. Botha4 and Robert J. Henry1,5* Abstract Background: Sugarcane is a major crop of the tropics cultivated mainly for its high sucrose content. The crop is genetically less explored due to its complex polyploid genome. Sucrose synthesis and accumulation are complex processes influenced by physiological, biochemical and genetic factors, and the growth environment. The recent focus on the crop for fibre and biofuel has led to a renewed interest on understanding the molecular basis of sucrose and biomass traits. This transcriptome study aimed to identify genes that are associated with and differentially regulated during sucrose synthesis and accumulation in the mature stage of sugarcane. Patterns of gene expression in high and low sugar genotypes as well as mature and immature culm tissues were studied using RNA-Seq of culm transcriptomes. Results: In this study, 28 RNA-Seq libraries from 14 genotypes of sugarcane differing in their sucrose content were used for studying the transcriptional basis of sucrose accumulation. Differential gene expression studies were performed using SoGI (Saccharum officinarum Gene Index, 3.0), SAS (sugarcane assembled sequences) of sugarcane EST database (SUCEST) and SUGIT, a sugarcane Iso-Seq transcriptome database. In total, about 34,476 genes were found to be differentially expressed between high and low sugar genotypes with the SoGI database, 20,487 genes with the SAS database and 18,543 genes with the SUGIT database at FDR < 0.01, using the Baggerley’s test.

Its activity toward these substrates Jeongmin An was investigated in the presence of Mg2+, Ni2+, Co2+, Mn2+, or ethylenediaminetetraacetic acid https://orcid.org/0000-0002-2357-0941 Jaiesoon Cho (EDTA). Michaelis constant (Km) and maximum reaction velocity (Vmax) were determined https://orcid.org/0000-0002-4511-8032 from Lineweaver-Burk plot with polyP75 or polyP1150. Monophosphate esterase activity toward p-nitrophenyl phosphate (pNPP) was assayed in the presence of polyP75 or polyP1150. Submitted Jan 16, 2019; Revised Apr 4, 2019; Accepted Apr 29, 2019 Results: Wheat phytase dephosphorylated polyP75 and polyP1150 at pH 7.5 more effectively than that at pH 5.2. Its exopolyphosphatase activity toward polyP75 at pH 5.2 was 1.4-fold higher than that toward polyP1150 whereas its activity toward polyP75 at pH 7.5 was 1.4-fold lower than that toward polyP1150.

  • Separation and Properties of the Haemolysins and Extracellular Enzymes of L Isteria Monocytogenes and L
    J. Med.

BARCLAY”, D. R. THRELFALL and I. LElGHTONt Department of Plant Biology, The University of Hull, Hull HU6 7RX and tDepartment of Microbiology, Hull Royal Infirmary, Anlaby Road, Hull HU3 2JZ Summary. Desalted ammonium-sulphate (045%) precipitates from the cell-free supernates of 16-24-h cultures of Listeria monocytogenes Boldy and L. ivanovii (previously L. monocytogenes) Type 5 were eluted through Sephadex G-200. The enzyme activities gave rise to two main peaks. The first peak (approximate mol. wt of protein 150 000) contained only phosphatase activity (assayed by hydrolysis of 4- nitrophenylphosphate at pH 5-0 and 7-0). The second peak (approximate mol. wts of proteins 40 000-60 000) contained the haemolysin activity and the following hydrolytic activities (assay substrates are given in parentheses) : phospholipase C (phosphatidyl choline and 4-ni trophenyl-phosphoryl-choline) ;phosphodiesterase (bis-4-nitrophenyl- phosphate) ; acid phosphatase (4-nitrophenylphosphatase) ; and esterases and lipases (4-nitrophenyl acetate, naphthyl-acetate and -oleate, triacetin and triolein). DEAE- Sephadex chromatography of appropriate fractions from the Sephadex G-200 purification step separated the first peak into two phosphatases and resolved the second peak into its constituent activities. Polyacrylamide gel electrophoresis showed that the individual fractions from the DEAE-Sephadex step consisted of mixtures of protein. The effects of pH and potential activators and inhibitors on the active proteins purified by DEAE-Sephadex chromatography were examined.

  • Most Ester-Type Drugs Are Hydrolyzed by Esterases Bound in the Intestinal Mucosa and the Degree of Hydrolysis Affects Pharmacological Activity Or Toxicity (1-3)
    SPECIES DIFFERENCE AND CHARACTERIZATION OF INTESTINAL ESTERASE ON THE HYDROLIZING ACTIVITY OF ESTER-TYPE DRUGS Michiko INOUE, Masako MORIKAWA, Minoru TSUBOI and Mamoru SUGIURA* Department of Pharmacology, Tokyo College of Pharmacy, Horinouchi, Hachioji-shi, Tokyo 192-03, Japan *Department of Pharmacy , Gifir College of Pharmacy, Mitahorahigashi, Gifu-shi, Gifu 502, Japan Accepted July 5, 1978 Abstract-The ability of the esterase from intestine was studied for hydrolysis of ester type drugs during absorption. The intestinal esterase is present in the absorption sites in the intestine and hydrolyzes to a large extent during the absorption. In a study of the dietary effect on intestinal esterase, the esterase activity increased in rats fed a high-fat diet, decreased in those fasted or fed a fat-free diet, whereas the esterase activity in the rat treated with phenobarbital showed no marked change. Thus the esterase from intestinal mucosa appears to be characteristically quite different from hepatic esterase. The esterase from human intestine was characterized and compared with esterase from rats, mice, rabbits, guinea pigs and dogs. There was a difference in the substrate specificity of the esterase and there were significant species differences in the electrophoretic behavior of the enzyme among the species tested. These results indicate that intestinal esterase from humans differs characteristically from esterases in experimental animals. Most ester-type drugs are hydrolyzed by esterases bound in the intestinal mucosa and the degree of hydrolysis affects pharmacological activity or toxicity (1-3). There are, however, only a few reports on the properties and characteristics of intestinal esterases (4-5) and apparently no documentation on human intestinal esterease.

Abstract: Plants are nonmotile life forms that are constantly exposed to changing environmental conditions during the course of their life cycle. Fluctuations in environmental conditions can be drastic during both day–night and seasonal cycles, as well as in the long term as the climate changes. Plants are naturally adapted to face these environmental challenges, and it has become increasingly apparent that membranes and their lipid composition are an important component of this adaptive response. Plants can remodel their membranes to change the abundance of different lipid classes, and they can release fatty acids that give rise to signaling compounds in response to environmental cues. Chloroplasts harbor the photosynthetic apparatus of plants embedded into one of the most extensive membrane systems found in nature. In part one of this review, we focus on changes in chloroplast membrane lipid class composition in response to environmental changes, and in part two, we will detail chloroplast lipid-derived signals.
