Per-Olof H. WikströmPlant identification usually requires the use of only a few of a plant’s more obvious morphological characteristics, and only one or two characteristics are usually considered at any one time as the plant is worked through the key. In plant classification, on the other hand, it is necessary to consi

Per-Olof H. Wikströmression systems, in which the foreign mRNA is greatly amplified by virus replication, can produce very high levels of proteins or peptides in leaves and other tissues. Vectors have been available for about 25 years. They are commonplace as laboratory tools, but their initial commercial expectations

Even though the citrus vectors were created as laboratory tools for improving the crop, circumstances have changed the applications to protection and therapy of trees in the field.

In future work on respiration rates of virus-diseased plants, it will be necessary to take these facts into consideration and also to apply adequate statistical tests of significance to any differences obtained.
