| integrin-like proteins in the pollen tube: detection, localization and function. | the distribution of integrin-like proteins in the pollen tube was examined by immunofluorescent labeling and western blotting techniques using antibodies against human placenta integrin vitronectin receptor (vnr), and alpha(v), beta3 and beta1 integrin subunits. pseudocolor-coded confocal images showed intense immunostaining within 10 and 5 microm of the tip of the pollen tube in lilium davidii and nicotiana tabacum respectively. in both segments the site near the plasma membrane was labeled. we ... | 2000 | 11148272 |
| chemical characterisation of polysaccharides from lilium davidii. | lilium davidii var. unicolor salisb is known for its esculent and exceptionally sweet bulbs. this article reports the isolation and purification of a non-starch polysaccharide from the bulb tissues. the polysaccharide was fractionated by sephadex g-100 column chromatography, giving two polysaccharide fractions. we collected the main peak polysaccharide, termed lilium davidii polysaccharide (ldp). the molecular appearance of ldp at different concentrations was observed with atomic force microscop ... | 2010 | 20221942 |
| small heat shock protein limhsp16.45 protects pollen mother cells and tapetal cells against extreme temperatures during late zygotene to pachytene stages of meiotic prophase i in david lily. | plant meiotic prophase i is a complicated process involving the late zygotene and pachytene stages, both crucial for completing synapsis and recombination. using david lily (lilium davidii var. willmottiae) as our research material, we performed suppression subtractive hybridization to construct est library of anthers at various stages of development by the pollen mother cells. from this library, we identified small heat shock protein limhsp16.45 was highly expressed during the late zygotene to ... | 2011 | 21678060 |
| in vitro study of the growth, development and pathogenicity responses of fusarium oxysporum to phthalic acid, an autotoxin from lanzhou lily. | continuous monoculture of lanzhou lily (lilium davidii var. unicolor cotton) results in frequent incidence of fusarium wilt caused by fusarium oxysporum. phthalic acid (pa), a principal autotoxin from root exudates of lanzhou lily, is involved in soil sickness by inducing autotoxicity. the aim of this study was to evaluate the direct allelopathic effects of pa on the growth, development and pathogenicity of f. oxysporum in vitro based on an ecologically relevant soil concentration. the results s ... | 2015 | 25994089 |
