Carnation (Dianthus caryophyllus L.) is one of the most important ornamental plants in the world. Though morphological modification of carnation is very important to its commercial value, there have been no relevant reports until now. PttKN1 (Populus tremula × Tremuoides knotted1), isolated from the vascular cambial region of hybrid aspen, is a novel member(More)
Though shoot apical meristems (SAMs) commonly exhibit low or no competence for transformation, the potent regeneration of this tissue merits further research. Especially, when shoot regeneration is recalcitrant using other tissues as explants, SAM probably is an excellent selection. In cockscomb plants, using SAMs from seedlings obtained from MS medium with(More)
The leaf primordium derives from the peripheral zone of shoot apical meristem. During the formation of leaf primordia, they need to establish the proximodistal, mediolateral, and ab/adaxial axes. Among these axes, the ab/adaxial axis might be the most important. ASYMMETRIC LEAVES2 (AS2) gene is a member of AS2/LATERAL ORGAN BOUNDARY (LOB) family of(More)
Gentiana dahurica Fisch is one of four important commercial Radix Gentianae stipulated by the Chinese Pharmacopoeia. We have established a rapid and effective regeneration system using zygotic embryo-derived callus of G.dahurica Fisch. Using this regeneration system, Agrobacteriumtumefaciens-mediated transformation of G. dahurica Fisch has been developed.(More)
This study focused on retrieval of net photosynthetic rate (Pn) of moso bamboo forest based on analysis of wavelet transform on hyperspectral reflectance data of moso bamboo forest leaf. The result showed that the accuracy of Pn retrieved by the ideal high frequency wavelet vegetation index ( VI) was higher than that retrieved by low frequency wavelet VI(More)
OBJECTIVES To investigate the radiosensitizing effects of Radix Angelicae Sinensis-Radix Hedysari (RAS-RH [an ultra-filtration extract]) and its underlying mechanisms in human liver cancer cells H22. METHODS This study was conducted between September 2010 and August 2012 in the Gansu University of Traditional Chinese Medicine, Lanzhou, China. The groups(More)
A water-dispersible and supermagnetic nanocomposite (PAD-PEG-Fe(3)O(4)@PEI) has been successfully synthesized using polyethylenimine (PEI, Mol MW = 10000) coated supermagnetic Fe(3)O(4)-NH(2) which was modified with 2, 2'-(phenylazanediyl) diacetic acid (PAD) through the bridge of poly(ethylene glycol) (PEG, Mol MW = 2000). The average particle size of(More)
Celosia plumosus L. is one of the most common gardening plants worldwide. The C. plumosus L. transformation system established by other research team should be useful for modifying physiological, medicinal, and horticultural traits. Though morphological modification of C. plumosus L. would be critical in terms of its commercial value, few attempts have been(More)
A new Schiff-base ligand (1) with good fluorescence response to Al(3+), derived from 2-oxo-quinoline-3-carbaldehyde and nicotinic hydrazide, had been synthesized and investigated in this paper. Spectroscopic investigation revealed that the compound 1 exhibited a high selectivity and sensitivity toward Al(III) ions over other commonly coexisting metal ions(More)
This study was designed to investigate the impact of ultra-filtration extract mixture from Astragals mongholicus (UEMAM) o radiosensitivity of H22 ascitic tumor in mice to 12C6+ ions radiation. The H22 ascitic tumor model was established in mice by intraperitoneal injection of 0.2 mL H22 ascitic cells. The animals were subsequently divided into 4 groups(More)
