Microarray expression analysis has become one of the most widely used functional genomics tools. Efficient application of this technique requires the development of robust and reproducible protocols. We have optimized all aspects of the process, including PCR amplification of target cDNA clones, microarray printing, probe labeling and hybridization, and have developed strategies for data normalization and analysis. 相似文献

Protoplasts were isolated enzymatically from haploid tobaccoleaves, then cultured in synthetic media. Cultured protoplastsstarted their first division within a few days after inoculationand subsequently developed into small colonies. After severalreinoculations, these colonies differentiated shoots and roots.Finally, haploid flowering plants were obtained.

Ecosystem services provided by agricultural ecosystems include natural pest control and pollination, and these are important to ensure crop productivity. This study investigates the use of the banker plant Calendula officinalis L. to provide multiple ecosystem services by increasing the abundance of natural enemies for biological control of tomato pests, providing forage resources to wild bees, and improving crop yield. C. officinalis was selected for this experiment as it is used as a banker plant for Dicyphini (Hemiptera: Miridae) predators. Strips of flowering C. officinalis were established in the field edges of tomato fields and arthropod visitation to C. officinalis strips and tomato was measured. Crop damage from multiple pests of tomato was assessed in fields with C. officinalis strips and control sites. The contribution of pollination to crop yield was assessed through a pollinator exclusion experiment. The inclusion of C. officinalis in tomato fields was associated with increased abundance of Dicyphini, parasitoids, bees and other arthropod groups within these strips. A reduction in the total leaf crop damage from Lepidoptera pests was recorded in fields with C. officinalis strips. Increased fruit set and biomass were recorded in open-pollinated tomato but this was not significantly different between control and C. officinalis fields. Results presented here demonstrate that the inclusion of a companion plant can improve the conservation of beneficial arthropods and the delivery of agroecosystem services but efficacy is likely to be improved with the addition of plants, with different functional traits, and with improved attractiveness to crop pollinators. 相似文献

Making discoveries is the most important part of being a scientist, and also the most fun. Young scientists need to develop the experimental and mental skill sets that enable them to make discoveries, including how to recognize and exploit serendipity when it strikes. Here, I provide practical advice to young scientists on choosing a research topic, designing, performing and interpreting experiments and, last but not least, on maintaining your sanity in the process. 相似文献

Biomedical research has never been more intellectually exciting or practically important to society. Ironically, pursuing a career as a biomedical scientist has never been more difficult. Here I provide unvarnished advice for young biomedical scientists on the difficulties that lie ahead and on how to find the right laboratories for training in the skills that you will need to succeed. Although my advice is geared towards succeeding in the United States, many aspects apply to other countries. 相似文献
