A nitriloside is a naturally occurring or synthetic compound which upon hydrolysis by a betaglucosidase yields a molecule of a non-sugar, or aglycone, a molecule of free hydrogen cyanide, and one or more molecules of a sugar or its acid. There are approximately 14 naturally occurring nitrilosides distributed in over 1200 species of plants. Nitrilosides are found in all plant phyla from Thalloph...

We have constructed a phylogenic tree for green plants by comparing 5S rRNA sequences. The tree suggests that the emergence of most of the uni- and multicellular green algae such as Chlamydomonas, Spirogyra, Ulva, and Chlorella occurred in the early stage of green plant evolution. The branching point of Nitella is a little earlier than that of land plants and much later than that of the above g...
