Recent advances in CRISPR/Cas mediated genome editing for crop improvement
Samriti Sharma,Rajinder Kaur,Anupama Singh 한국식물생명공학회 2017 Plant biotechnology reports Vol.11 No.4
Plant breeding is one of the oldest sustainable agriculture methods used to increase the yield, quality and other biomaterial for human use. Many crops like fruits, vegetables, ornamental flowers, shrubs and trees, have been long cultivated to satisfy human food and aesthetical needs. Conventional breeding technologies like selection, hybridization, mutation through physical and chemical methods, and modern transgenic approaches are often used to improve the desired traits without inducing the pleiotropic effects. But these breeding methods are highly laborious and complicated to enhance crop production. Recently, targeted genome editing through engineered nuclease including zinc finger nuclease, transcription activator like effector nuclease and clustered regularly interspaced short palindromic repeats (CRISPRs) have been used to improve various traits in plants. Genome editing has emerged as a novel alternative approach to classical breeding with higher mutagenic efficiency. Here, we briefly cover the strengths of CRISPRs in comparison with other genome editing techniques. We also discuss its potential applications in genetic improvement of various crops and future prospective.
Dielectric behavior of carbon-nanotube-doped ferroelectric liquid crystal mixture
Samriti Khosla,Arti Sharma 한국정보디스플레이학회 2013 Journal of information display Vol.14 No.4
The dielectric spectra of pure and 0.1% multi-walled-carbon-nanotube-(MWCNT)-doped ferroelectric liquid crystal (FLC)mixture KCFLC10S materials were studied in the 50 Hz to 1MHz frequency range at different bias voltages. An unusual behavior-increase of ε with increasing E was observed in both samples. It was found that although the relaxation mode was not observable in the MWCNT-FLC sample, the increased effect of the bias voltage on the FLC with the addition of MWCNTs is clearly visible. A theory is presented to explain this effect of MWCNTs in the FLC material.
