Springerplus. 2016 May 04;5:559. doi: 10.1186/s40064-016-2173-x. eCollection 2016.

The present study demonstrated the simultaneous production and optimization of pectinolytic enzymes (pectate lyase and polygalacturonase) under SSF from Bacillus tequilensis SV11-UV37 using wheat bran as a substrate, which is commercially viable and cost-effective. Optimization by one variable-at-a-time-approach showed...

Polygalacturonase-inhibiting protein (PGIP) is a cell wall protein which inhibits fungalendopolygalacturonases. A small gene family encodesPGIP in the genome of common bean, as indicated by Southernblot experiments performed at high-stringency conditions. Southern-blot analysis of DNA extracted from different cultivars...

Induction of polygalacturonase and the formation of oxalic acid by pectin in brown-rot fungi.

World journal of microbiology & biotechnology

Green F, Clausen CA, Kuster TA, Highley TL.
PMID: 24414906
World J Microbiol Biotechnol. 1995 Sep;11(5):519-24. doi: 10.1007/BF00286366.

Extracellular polygalacturonase (PG) production was estimated in vitro, using liquid cultures of three species of brown-rot decay fungi (Postia placenta, Gloeophyllum trabeum and Serpula incrassata), by cup-plate assay, assay of reducing sugars, and decrease in viscosity. Although all three...

Detection of polygalacturonases and pectin esterases in lactic acid bacteria.

World journal of microbiology & biotechnology

Karam NE, Belarbi A.
PMID: 24414913
World J Microbiol Biotechnol. 1995 Sep;11(5):559-63. doi: 10.1007/BF00286373.

Of 80 strains of lactic acid bacteria tested, only Lactobacillus casei strains HNK10 and L1-8, Lactobacillus plantarum Lc5 and Lactococcus lactis NN01 produced polygalacturonases (EC 3.2.1.) and/or pectin-esterases (EC 3.1.1.). Crude extracellular extracts of strain L1-8 were able to...

Tomatine Content in Host and Transgenic Tomatoes by Absorptiometric Measurement.

Bioscience, biotechnology, and biochemistry

Furui H, Inakuma T, Ishiguro Y, Kiso M.
PMID: 27315931
Biosci Biotechnol Biochem. 1998;62(3):556-7. doi: 10.1271/bbb.62.556.

Tomatine is a steroidal glycoalkaloid in tomato plants (Lycopersicon esculentum) and other Lycopersicon and Solanum Species. Tomatine is used as an indicator to evaluate the safety of transgenic tomatoes by FDA in U.S.A. We have developed a facile and...

The Transcription Factor AtDOF4.7 Is Involved in Ethylene- and IDA-Mediated Organ Abscission in Arabidopsis.

Frontiers in plant science

Front Plant Sci. 2016 Jun 17;7:863. doi: 10.3389/fpls.2016.00863. eCollection 2016.

Organ abscission is an important plant developmental process that occurs in response to environmental stress or pathogens. In Arabidopsis, ligand signals, such as ethylene or INFLORESCENCE DEFICIENT IN ABSCISSION (IDA), can regulate organ abscission. Previously, we reported that overexpression...

Extracellular polysaccharidases synthesized by the epiphytic lichen Evernia prunastri (L.) Ach.
