Stigmatic exudate, a secretion product recovered from the upper surface of Lilium longiflorum pistils, has been examined. Over 99% of the exudate is accounted for as water, carbohydrate, and protein. Exclusive of water, 95% is a high molecular weight, protein-containing polysaccharide composed of
Although HsfA3 (heat-stress transcription factor A3) is well characterized in heat stress, its roles in other abiotic stresses are less clear. In this study, we isolated two homologous HsfA3 genes, LlHsfA3A and LlHsfA3B, from lily (Lilium longiflorum). Both genes were induced by heat stress, but not
Previously, we have shown that excess profilin inhibits pollen tube growth at significantly lower concentrations than it blocks cytoplasmic streaming. To elucidate the mechanism by which profilin achieves this function, we have employed mutant profilins from Schizosaccharomyces pombe [J. Lu and T.D.
The actin cytoskeleton is critical for tip growth in plants. Profilin is the main monomer actin binding protein in plant cells. The moss Physcomitrella patens has three profilin genes, which are monophyletic, suggesting a single ancestor for plant profilins. Here, we used RNA interference (RNAi) to
NACs are one of the largest transcription factor families in plants and are involved in the response to abiotic stress. A new stress-responsive NAC transcription factor gene, LpNAC13, was isolated from Lilium pumilum bulbs. The expression of LpNAC13 was induced by drought, salt, cold and ABA
Low temperature induces changes in plants at physiological and molecular levels, thus affecting growth and development. The Lanzhou lily (Lilium davidii, var. unicolor) is an important medicinal plant with high economic value. However, the molecular mechanisms underlying its photosynthetic and
