| quantitative comparison of stylet penetration behaviors of glassy-winged sharpshooter on selected hosts. | new zealand is threatened by invasion of the glassy-winged sharpshooter, homalodisca vitripennis (germar) (hemiptera: cicadellidae), an important vector of xylella fastidiosa, a gram-negative bacterium that causes pierce's disease in grape (vitis spp.) and scorch diseases in many other horticultural crops. therefore, an understanding of the host acceptability, feeding behavior, and potential vector efficiency of glassy-winged sharpshooter on new zealand crops is important. we tested host plant a ... | 2008 | 18767727 |
| flowering genes in metrosideros fit a broad herbaceous model encompassing arabidopsis and antirrhinum. | molecular studies were conducted on metrosideros excelsa to determine if the current genetic models for flowering with regard to inflorescence and floral meristem identity genes in annual plants were applicable to a woody perennial. mel, mesap1 and metfl1, the fragments of leafy (lfy), apetala1 (ap1) and terminal flower1 (tfl1) equivalents, respectively, were isolated from m. excelsa. temporal expression patterns showed that mel and mesap1 exhibited a bimodal pattern of expression. expression ex ... | 2004 | 15086830 |
