Arabidopsis ROOT HAIR DEFECTIVE3 is involved in nitrogen starvation‐induced anthocyanin accumulation

10.12.2014 | Jing Wang, Yan Wang, Ju Yang, Chunli Ma, Ying Zhang, Ting Ge, Zhi Qi, Yan Kang, Journal of Integrative Plant Biology, 2014

Abstract Anthocyanin accumulation is a common phenomenon seen in plants under environmental stress. In this study, we identified a new allele of ROOT HAIR DEFECTIVE3 (RHD3) showing an anthocyanin overaccumulation phenotype under nitrogen starvation conditions. It is known that ethylene ...

A new point mutation in the iron‐sulphur subunit of succinate dehydrogenase confers resistance to boscalid in Sclerotinia sclerotiorum

02.12.2014 | Yong Wang, Yabing Duan, Jianxin Wang, Mingguo Zhou, Molecular Plant Pathology, 2014

Summary Research has established that mutations in highly conserved amino acids of the succinate dehydrogenase (SDH) complex in various fungi confers SDHI resistance. For Sclerotinia sclerotiorum (Lib.) de Bary, a necrotrophic fungus with a broad host range and a worldwide distribution, ...

Seed biopriming with drought tolerant isolates of Trichoderma harzianum promote growth and drought tolerance in Triticum aestivum

02.12.2014 | N. Shukla, R.P. Awasthi, L. Rawat, J. Kumar, Annals of Applied Biology, 2014

Abstract Green house study was aimed to investigate the effect of seed biopriming with drought tolerant isolates of Trichoderma harzianum, viz. Th 56, 69, 75, 82 and 89 on growth of wheat under drought stress and to explore the mechanism underlying plant water stress resilience in response to ...

Using Improved Serial Blood Sampling Method of Mice to Study Pharmacokinetics and Drug–Drug Interaction

01.12.2014 | Ayahisa Watanabe, Ryosuke Watari, Keiko Ogawa, Ryosuke Shimizu, Yukari Tanaka, Nozomi Takai, Ken‐Ichi Nezasa, Yoshit ..., Journal of Pharmaceutical Sciences, 2014

In pharmacokinetic evaluation of mice, using serial sampling methods rather than a terminal blood sampling method could reduce the number of animals needed and lead to more reliable data by excluding individual differences. In addition, using serial sampling methods can be valuable for ...

Emission of methane, carbon monoxide, carbon dioxide and short‐chain hydrocarbons from vegetation foliage under ultraviolet irradiation

01.12.2014 | WESLEY T. FRASER, EMANUEL BLEI, STEPHEN C. FRY, MARK F. NEWMAN, DAVID S. REAY, KEITH A. SMITH, ANDY R. MCLEOD, Plant, Cell & Environment, 2014

Abstract The original report that plants emit methane (CH4) under aerobic conditions caused much debate and controversy. Critics questioned experimental techniques, possible mechanisms for CH4 production and the nature of estimating global emissions. Several studies have now confirmed that ...

Probing the elastic limit of DNA bending

01.12.2014 | Tung T. Le; Harold D. Kim, Nucleic Acids Research, 2014

Sharp bending of double-stranded DNA (dsDNA) plays an essential role in genome structure and function. However, the elastic limit of dsDNA bending remains controversial. Here, we measured the opening rates of small dsDNA loops with contour lengths ranging between 40 and 200 bp using ...

Transcriptome analysis reveals novel regulatory mechanisms in a genome-reduced bacterium

01.12.2014 | Pavel V. Mazin; Gleb Y. Fisunov; Alexey Y. Gorbachev; Kristina Y. Kapitskaya; Ilya A. Altukhov; Tatiana A. Semashko; ..., Nucleic Acids Research, 2014

The avian bacterial pathogen Mycoplasma gallisepticum is a good model for systems studies due to small genome and simplicity of regulatory pathways. In this study, we used RNA-Seq and MS-based proteomics to accurately map coding sequences, transcription start sites (TSSs) and transcript 3'-ends ...

[Immunology] Inflammasomes

01.12.2014 | Marcel R. de Zoete; Noah W. Palm; Shu Zhu; Richard A. Flavell, CSH Perspectives, 2014

Inflammasomes are large cytosolic multiprotein complexes that assemble in response to detection of infection- or stress-associated stimuli and lead to the activation of caspase-1-mediated inflammatory responses, including cleavage and unconventional secretion of the leaderless proinflammatory ...

Inhibition in the lateral septum increases sucrose intake and decreases anorectic effects of stress

24.11.2014 | Arojit Mitra, Christophe Lenglos, Elena Timofeeva, European Journal of Neuroscience, 2014

Abstract Sucrose‐overeating rats with decreased anorectic response to stress showed lower stress‐induced activation of c‐fos expression in the lateral septum (LS). The present study tested a hypothesis that neuronal inhibition in the LS is important for the development and maintenance of the ...

Heat-Induced Release of Epigenetic Silencing Reveals the Concealed Role of an Imprinted Plant Gene

20.11.2014 | Diego H. Sanchez et al., PLoS Genetics, 2014

by Diego H. Sanchez, Jerzy Paszkowski Epigenetic mechanisms suppress the transcription of transposons and DNA repeats; however, this suppression can be transiently released under prolonged heat stress. Here we show that the Arabidopsis thaliana imprinted gene SDC, which is silent during ...
