Overexpression of a New Putative Membrane Protein Gene AtMRB1 Results in Organ Size Enlargement in Arabidopsis

引用

Journal of Integrative Plant Biology 2009年第2期51卷 130-139页

Arabidopsis AtMRB1 is predicted to encode a novel protein of 432 amino acid residues in length, with four putative transmembrane domains. In the present study, characterization of AtMRB1 is conducted. Green fluorescent protein （GFP） fusion protein assay showed that AtMRB1 was located in the plasma membrane. Transgenic lines overexpressing AtMRB1 driven by a CaMV 35S promoter were generated. Statistic analysis showed that, during the seedling stage, the organ sizes of the transgenic lines including hypocotyl length, root length and root weight were significantly larger than those of the wild type plants under both light and dark conditions. In the adult plant stage, the AtMRB1 overexpressor plants were found to have larger organ sizes in terms of leaf length and width, and increased number of cauline leaves and branches when bolting. Further observation indicated that the larger leaf size phenotype was due to a larger number of mesophyll cells, the size of which was not altered. quantitative real-time polymerase chain reaction analysis showed that the transcription of ANT, ROT3 and GRF5 were upregulated in the *** plants. These data suggest that AtMRB1 is possibly a positive regulator of organ size development in Arabidopsis, mainly through cell number control.

Hormonal Regulation of Leaf Morphogenesis in Arabidopsis

引用

Journal of Integrative Plant Biology 2007年第1期49卷 75-80页

作者： Lin-Chuan Li Ding-Ming kang Zhang-Liang Chen Li-jia qu National Laboratory for Protein Engineering and Plant Genetic Engineering Peking-Yale Joint Research Center for Plant Molecular Genetics and AgroBiotechnology College of Life Sciences Peking University Beijing 100871 China Key Laboratory of Crop Genomics and Genetic Improvement of Ministry of Agriculture/Key laboratory of Crop Genetic Improvement of Beijing City College of Agronomy and Biotechnology China Agricultural University Beijing 100094 China

Leaf morphogenesis is strictly controlled not only by intrinsic genetic factors, such as transcriptional factors, but also by environmental cues, such as light, water and pathogens. Nevertheless, the molecular mechanism of how leaf morphogenesis is regulated by genetic programs and environmental cues is far from clear. Numerous series of events demonstrate that plant hormones, mostly small and simple molecules, play crucial roles in plant growth and development, and in responses of plants to environmental cues such as light. With more and more genetics and molecular evidence obtained from the model plant Arabidopsis, several fundamental aspects of leaf morphogenesis including the initiation of leaf primordia, the determination of leaf axes, the regulation of cell division and expansion in leaves have been gradually unveiled. Among these phytohormones, auxin is found to be essential in the regulation of leaf morphogenesis.
