Optimization of a DNA Nicking Assay to Evaluate Oenocarpus bataua and Camellia sinensis Antioxidant Capacity

09/10/2014 00:00
Louis-Jérôme Leba, Christel Brunschwig, Mona Saout, Karine Martial, Emmanuelle Vulcain, Didier Bereau and Jean-Charles Robinson   Résumé: This study was aimed at assessing the DNA damage protective activity of different types of extracts (aqueous, methanolic and acetonic) using an in vitro DNA nicking assay. Several parameters were optimized using the pUC18 plasmid, especially FeSO4, EDTA, solvent concentrations and incubation time. Special attention has been paid to removing the...

Ehsan Mehmood Bhatti, Naureen Aziz Qureshi, Fayyaz Rasool, Muhammad Siddique and Abu Baker Siddiqui   Résumé: In  Pakistan  the  work  on  genetic  of  different  populations  of Channa  marulius have  not  been  performed  so  for  and  the Clustering analysis was done  to find out the  intraspecific variations among different populations of Channa marulius using Pearson  Correlation ...

Mechanical properties and petrographic characteristics of Margala Hill limestone and Lockhart limestone of Rumli area, Islamabad Pakistan

27/09/2014 00:00
Mustansar Naeem, Rana Ahmad BinSadiq, Masood Anwar, Perveiz Khalid   Résumé: This study has been carried out to investigate the effect of petrographic characteristics on mechanical properties of Margala Hill limestone and Lockhart limestone of Rumli area, Islamabad, Pakistan. Mechanical properties, in terms of unconfined compressive strength (UCS), were computed by using point load test. Petrographic study reveals calcite and bioclasts as principal constituents of these limestones. These...

The auxin Sl-IAA17 transcriptional repressor controls fruit size via the regulation of the endoreduplication-related cell expansion

16/09/2014 00:00
Liyan Su, Carole Bassa, Corinne Audran, Catherine Cheniclet, Christian Chevalier, Mondher Bouzayen, Jean-Paul Roustan and Christian Chervin   Résumé: Auxin is known to regulate cell division and cell elongation, thus controlling plant growth and development. Part of the auxin signaling pathway depends on the fine tuned degradation of the Aux/IAA transcriptional repressors. Recent evidence indicates that Aux/IAA proteins play a role in fruit development in tomato (Solanum lycopersicum...

The Plant Pathogen Xanthomonas campestris pv. campestris Exploits N-Acetylglucosamine during Infection

09/09/2014 00:00
Alice Boulanger, Claudine Zischek, Martine Lautier Stevie Jamet, Pauline Rival, Sébastien Carrère, Matthieu Arlat and Emmanuelle Lauber   Résumé: N-Acetylglucosamine (GlcNAc), the main component of chitin and a major constituent of bacterial peptidoglycan, is present only in trace amounts in plants, in contrast to the huge amount of various sugars that compose the polysaccharides of the plant cell wall. Thus, GlcNAc has not previously been considered a substrate exploited by...

Isolation and molecular characterization of ERF1, an ethylene response factor gene from durum wheat (Triticum turgidum L. subsp. durum), potentially involved in salt-stress responses

09/09/2014 00:00
Emna Makhloufi, Fatma-Ezzahra Yousfi, William Marande, Isabelle Mila, Mohsen Hanana, Hélène Bergès, Rim Mzid and Mondher Bouzayen   Résumé: As food crop, wheat is of prime importance for human society. Nevertheless, our understanding of the genetic and molecular mechanisms controlling wheat productivity conditions has been, so far, hampered by the lack of sufficient genomic resources. The present work describes the isolation and characterization of TdERF1, an ERF gene from durum wheat...

Development of a SNP marker assay for the Lr67 gene of wheat using a genotyping by sequencing approach

13/08/2014 13:44
Kerrie Forrest, Vincent Pujol, Peter Bulli, Michael Pumphrey, Colin Wellings, Sybil Herrera-Foessel, Julio Huerta-Espino, Ravi Singh, Evans Lagudah, Matthew Hayden and Wolfgang Spielmeyer   Résumé: The recently characterised and mapped adult plant resistance gene Lr67 contributes to the breeding of durable resistance against multiple fungal pathogens of wheat. Lack of tightly linked markers has so far prevented widespread use of Lr67 in breeding programmes. Exhaustive screening of...

The conserved PFT1 tandem repeat is crucial for proper flowering in Arabidopsis thaliana

12/08/2014 00:00
Pauline Rival, Maximilian O Press, Jacob Bale, Tanya Grancharova, Soledad F Undurraga, Christine Queitsch   Résumé: It is widely appreciated that short tandem repeat (STR) variation underlies substantial phenotypic variation in organisms. Some propose that the high mutation rates of STRs in functional genomic regions facilitate evolutionary adaptation. Despite their high mutation rate, some STRs show little to no variation in populations. One such STR occurs in the Arabidopsis thaliana...

Aquaporin regulation in poplar and spruce trees under environmental change

16/07/2014 00:00
Laur Joan   Résumé: This dissertation describes a series of experiments that examined: 1) hydraulic responses of Populus trichocarpa x deltoides, Populus trichocarpa and Picea glauca plants to change in their surrounding environment; 2) Changes of aquaporin expression in response to such changes. In the first study, we demonstrated that changes of the transpirational demand is related to fine adjustment of root water uptake that is associated with up-regulation of plasma membrane intrinsic...

PIRIN2 stabilizes cysteine protease XCP2 and increases susceptibility to the vascular pathogen Ralstonia solanacearum in Arabidopsis

20/06/2014 00:00
Bo Zhang, Dominique Tremousaygue, Nicolas Denancé, H. Peter van Esse, Anja C. Hörger, Patrick Dabos, Deborah Goffner, Bart P. H. J. Thomma, Renier A. L. van der Hoorn and Hannele Tuominen   Résumé: PIRIN (PRN) is a member of the functionally diverse cupin protein superfamily. There are four members of the Arabidopsis thaliana PRN family, but roles of these proteins are largely unknown. Here we describe a function of the Arabidopsis PIRIN2 (PRN2) that is related to susceptibility to the...
