Roles of arabidopsis WRKY18, WRKY40 and WRKY60 transcription factors in plant responses to abscisic acid and abiotic stress Tập 10 Số 1 - 2010
Han Chen, Zhibing Lai, Junwei Shi, Yong Xiao, Zhixiang Chen, Xinping Xu
Abstract Background WRKY transcription factors are involved in plant responses
to both biotic and abiotic stresses. Arabidopsis WRKY18, WRKY40, and WRKY60
transcription factors interact both physically and functionally in plant defense
responses. However, their role in plant abiotic stress response has not been
directly analyzed. Results We report that the three WRKYs are involved in plant

BRAD, the genetics and genomics database for Brassica plants - 2011
Feng Cheng, Liu S, Jian Wu, Fang Lü, Silong Sun, Bo Liu, Pingxia Li, Wei Hua, Xiaowu Wang
Abstract Background Brassica species include both vegetable and oilseed crops,
which are very important to the daily life of common human beings. Meanwhile,
the Brassica species represent an excellent system for studying numerous aspects
of plant biology, specifically for the analysis of genome evolution following
polyploidy, so it is also very important for scientific research. Now, the
genome of... hiện toàn bộ
Pectic homogalacturonan masks abundant sets of xyloglucan epitopes in plant cell walls Tập 8 Số 1 - 2008
Susan E. Marcus, Yves Verhertbruggen, Cécile Hervé, José Juan Ordaz-Ortíz, Vladimı́r Farkaš, Henriette L. Pedersen, William G.T. Willats, John Knox
Abstract Background Molecular probes are required to detect cell wall polymers
in-situ to aid understanding of their cell biology and several studies have
shown that cell wall epitopes have restricted occurrences across sections of
plant organs indicating that cell wall structure is highly developmentally
regulated. Xyloglucan is the major hemicellulose or cross-linking glycan of the
primary cell ... hiện toàn bộ
Discovery of chemically induced mutations in rice by TILLING Tập 7 Số 1 - 2007
Bradley J. Till, Jennifer L. Cooper, Thomas H. Tai, Peter M. Colowit, Elizabeth A. Greene, Steven Henikoff, Luca Comai
Abstract Background Rice is both a food source for a majority of the world's
population and an important model system. Available functional genomics
resources include targeted insertion mutagenesis and transgenic tools. While
these can be powerful, a non-transgenic, unbiased targeted mutagenesis method
that can generate a range of allele types would add considerably to the analysis
of the rice gen... hiện toàn bộ
Validation of reference genes for quantitative real-time PCR during leaf and flower development in Petunia hybrida - 2010
Izaskun Mallona, Sandra Lischewski, Julia Weiß, Bettina Hause, Marcos Egea‐Cortines
Abstract Background Identification of genes with invariant levels of gene
expression is a prerequisite for validating transcriptomic changes accompanying
development. Ideally expression of these genes should be independent of the
morphogenetic process or environmental condition tested as well as the methods
used for RNA purification and analysis. Results In an effort to identify
endogenous genes m... hiện toàn bộ
