Tóm tắt Bacillus thuringiensis (Bt) là một loại vi khuẩn trong đất hình thành
bào tử trong giai đoạn trì trệ của chu trình phát triển của nó. Các bào tử chứa
các tinh thể, chủ yếu là một hoặc nhiều protein Cry và/hoặc Cyt (còn được gọi là
δ-endotoxin) có hoạt tính diệt côn trùng mạnh và đặc hiệu. Các chủng Bt khác
nhau tạo ra các loại độc tố khác nhau, mỗi loại ảnh hưởng đến một nhóm phân loại

WRKY transcription factors: key components in abscisic acid signalling Tập 10 Số 1 - Trang 2-11 - 2012
Deena L. Rushton, Prateek Tripathi, Roel Rabara, Jun Lin, Patricia Ringler, Ashley K. Boken, Tanner J. Langum, Lucas Smidt, Darius D. Boomsma, Nicholas J. Emme, Xianfeng Chen, John J. Finer, Qingxi J. Shen, Paul J. Rushton
SummaryWRKY transcription factors (TFs) are key regulators of many plant
processes, including the responses to biotic and abiotic stresses, senescence,
seed dormancy and seed germination. For over 15 years, limited evidence has been
available suggesting that WRKY TFs may play roles in regulating plant responses
to the phytohormone abscisic acid (ABA), notably some WRKY TFs are ABA‐inducible

Improvement of stress tolerance of wheat and barley by modulation of expression of DREB/CBF factors Tập 9 Số 2 - Trang 230-249 - 2011
Sarah Morran, Omid Eini, Tatiana Pyvovarenko, Boris Parent, Rohan Singh, Ainur Ismagul, Serik Eliby, Neil J. Shirley, Peter Langridge, Sergiy Lopato
SummaryTranscription factors have been shown to control the activity of multiple
stress response genes in a coordinated manner and therefore represent attractive
targets for application in molecular plant breeding. We investigated the
possibility of modulating the transcriptional regulation of drought and cold
responses in the agriculturally important species, wheat and barley, with a view
to incr... hiện toàn bộ
RNA‐guided transcriptional regulation in planta via synthetic dCas9‐based transcription factors Tập 13 Số 4 - Trang 578-589 - 2015
Agnieszka Piatek, Zahir Ali, Hatoon Baazim, Lixin Li, Aala A. Abulfaraj, Sahar A. Alshareef, Mustapha Aouida, Magdy M. Mahfouz
SummaryTargeted genomic regulation is a powerful approach to accelerate trait
discovery and development in agricultural biotechnology. Bacteria and archaea
use clustered regularly interspaced short palindromic repeats (CRISPRs) and
CRISPR‐associated (Cas) regulatory systems for adaptive molecular immunity
against foreign nucleic acids introduced by invading phages and conjugative
plasmids. The typ... hiện toàn bộ
Single nucleotide polymorphism (SNP) discovery in the polyploid Brassica napus using Solexa transcriptome sequencing Tập 7 Số 4 - Trang 334-346 - 2009
Martin Trick, Yan Long, Jinling Meng, Ian Bancroft
SummaryOilseed rape (Brassica napus) was selected as an example of a polyploid
crop, and the Solexa sequencing system was used to generate approximately 20
million expressed sequence tags (ESTs) from each of two cultivars: Tapidor and
Ningyou 7. A methodology and computational tools were developed to exploit, as a
reference sequence, a publicly available set of approximately 94 000 Brassica

Drought coping strategies in cotton: increased crop per drop Tập 15 Số 3 - Trang 271-284 - 2017
Abid Ullah, Heng Sun, Xiyan Yang, Xianlong Zhang
SummaryThe growth and yield of many crops, including cotton, are affected by
water deficit. Cotton has evolved drought specific as well as general
morpho‐physiological, biochemical and molecular responses to drought stress,
which are discussed in this review. The key physiological responses against
drought stress in cotton, including stomata closing, root development, cellular
adaptations, photosy... hiện toàn bộ
DNA barcoding: an efficient tool to overcome authentication challenges in the herbal market Tập 14 Số 1 - Trang 8-21 - 2016
Prachi Mishra, Amit Kumar, Akshitha Nagireddy, Daya N. Mani, Ashutosh K. Shukla, Rakesh K. Tiwari, Velusamy Sundaresan
SummaryThe past couple of decades have witnessed global resurgence of
herbal‐based health care. As a result, the trade of raw drugs has surged
globally. Accurate and fast scientific identification of the plant(s) is the key
to success for the herbal drug industry. The conventional approach is to engage
an expert taxonomist, who uses a mix of traditional and modern techniques for
precise plant iden... hiện toàn bộ
Intragenesis and cisgenesis as alternatives to transgenic crop development Tập 11 Số 4 - Trang 395-407 - 2013
Inger Bæksted Holme, Toni Wendt, Preben Bach Holm
SummaryOne of the major concerns of the general public about transgenic crops
relates to the mixing of genetic materials between species that cannot hybridize
by natural means. To meet this concern, the two transformation concepts
cisgenesis and intragenesis were developed as alternatives to transgenesis. Both
concepts imply that plants must only be transformed with genetic material
derived from t... hiện toàn bộ
Ferulic acid: a key component in grass lignocellulose recalcitrance to hydrolysis Tập 13 Số 9 - Trang 1224-1232 - 2015
Dyoni Matias de Oliveira, Aline Finger‐Teixeira, Thatiane Rodrigues Mota, Victor Hugo Salvador, Flávia Carolina Moreira‐Vilar, Hugo Bruno Correa Molinari, R. A. C. Mitchell, Rogério Marchiosi, Osvaldo Ferrarese‐Filho, Wanderley Dantas dos Santos
SummaryIn the near future, grasses must provide most of the biomass for the
production of renewable fuels. However, grass cell walls are characterized by a
large quantity of hydroxycinnamic acids such as ferulic and p‐coumaric acids,
which are thought to reduce the biomass saccharification. Ferulic acid (FA)
binds to lignin, polysaccharides and structural proteins of grass cell walls
cross‐linking... hiện toàn bộ
Targeted knockouts of Physcomitrella lacking plant‐specific immunogenic N‐glycans Tập 2 Số 6 - Trang 517-523 - 2004
Anna Kopřivová, Christian Stemmer, Friedrich Altmann, Axel Hoffmann, Stanislav Kopřiva, Gilbert Gorr, Ralf Reski, Eva L. Decker
SummaryUsing plants as production factories for therapeutic proteins requires
modification of their N‐glycosylation pattern because of the immunogenicity of
plant‐specific sugar residues. In an attempt towards such humanization, we
disrupted the genes for α1,3‐fucosyltransferase and β1,2‐xylosyltransferase in
Physcomitrella patens by homologous recombination. The single Δfuc‐t and Δxyl‐t
plants, a... hiện toàn bộ
