Functional conservation and divergence of -like genes in floral development in .

is one of the most important traditional Chinese Orchids due to its unique and highly ornamental floral organs. Although the ABCDE model for flower development is well-established in model plant species, the precise roles of these genes in are not yet fully understood. In this study, four -like genes were isolated and identified from .

Comparative Analysis of Water-Soluble Polysaccharides from Second Love 'Tokimeki' and in Structure, Antioxidant, and Anti-Tumor Activity In Vitro.

With potential anti-tumor and antioxidant properties, the polysaccharide content of is relatively lower than that of the other medicinal To find high-content polysaccharide resources, the polysaccharide (DHPP-Ⅰs) was prepared from Second Love 'Tokimeki' (a hybrid) and compared with DNPP-Ⅰs from . DHPP-Is (Mn 31.09 kDa) and DNPP-Is (Mn 46.

H-NMR Karplus Analysis of Molecular Conformations of Glycerol under Different Solvent Conditions: A Consistent Rotational Isomerism in the Backbone Governed by Glycerol/Water Interactions.

Glycerol is a symmetrical, small biomolecule with high flexibility in molecular conformations. Using a H-NMR spectroscopic Karplus analysis in our way, we analyzed a rotational isomerism in the glycero backbone which generates three kinds of staggered conformers, namely gt (-), gg (-), and tg (-), at each of -1,2 and -2,3 positions. The Karplus analysis has disclosed that the three rotamers are consistently equilibrated in water keeping the relation of 'gt:gg:tg = 50:30:20 (%)' at a wide range of concentrations (5 mM~540 mM).

The genome of Cymbidium sinense revealed the evolution of orchid traits.

The Orchidaceae is of economic and ecological importance and constitutes ˜10% of all seed plant species. Here, we report a genome physical map for Cymbidium sinense, a well-known species belonging to genus Cymbidium that has thousands of natural variation varieties of flower organs, flower and leaf colours and also referred as the King of Fragrance, which make it arose into a unique cultural symbol in China. The high-quality chromosome-scale genome assembly was 3.

Early Cold-Induced Peroxidases and Aquaporins Are Associated With High Cold Tolerance in Dajiao ( spp. 'Dajiao').

Banana is an important tropical fruit with high economic value. One of the main cultivars ('Cavendish') is susceptible to low temperatures, while another closely related specie ('Dajiao') has considerably higher cold tolerance. We previously reported that some membrane proteins appear to be involved in the cold tolerance of Dajiao bananas via an antioxidation mechanism.
