Here's a gift idea for that botanical geek in your family. A deck of cards illustrating plant families with a Linnaeus on the back. These were especially made in honor of Linnaeus' 300th anniversary by the Chelsea Physic Garden, which was established in 1673 by the Worshipful Society of Apothecaries so apprentices could learn to identify medicinal plants. It's only been open to the public for the last few decades. I had to buy a deck when I visited this last May.
Appropriately enough the garden is located at 66 Royal Hospital Road. It's not very big actually, but is crammed full with over 5000 species of plants all labelled. Many are arranged taxonomically; others are grouped medically. I was going to include an image, but they have gone missing.
Does expression of the toxA operon depend on ToxT as well as ToxA?
