The march of thyme
I am most honoured by your invitation to speak at this meeting of the Shanghai Institute of Bio-historiography. As many of you know, I work at the University of San Francisco de Crico, in that remote Pacific province of the Spanish Empire, Hispano-America, and I am interested mainly in the early history of plant genetic engineering, that obscure period covering the end of the 20th century (old ...
متن کاملA chemical polymorphism in a multitrophic setting: thyme monoterpene composition and food web structure.
We investigated the effects of chemical variation in thyme (Thymus vulgaris L.) on its interactions with competitors, herbivores, and herbivore predators. Four different thyme monoterpene phenotypes (chemotypes) were grown in a 4x2x2 factorial of chemotype, caging (sham half-cages vs. full cages), and competition (control vs. the grass Bromus madritensis L.). Cages reduced numbers of arthropod ...
متن کاملGenetic interactions among late-flowering mutants of Arabidopsis.
Flowering time in Arabidopsis is controlled by a large number of genes, identified by induced mutations. Forty-two double mutants involving 10 of these loci were obtained and analyzed for their flowering behavior under long-day conditions, with and without vernalization, and under short-day conditions. The genetic interactions between the various mutants proved to be complex, although a major e...
متن کاملRibosome Rocks
If we are to talk about molecules of life, the ribosome, made of ribosomal RNA (rRNA) and protein, is a key: it stands at the junction between information and action, i.e. between nucleic acids and proteins. It is an extraordinarily sophisticated machine that takes the information present in mRNA and uses it to build proteins, containing over 250K atoms, and measuring more than 200 in every dir...
متن کاملLunar Rocks
The Moon, like the Earth, is made of rocks. To learn about the Moon and its history, one has to learn something about lunar rocks—what they are made of, how they are studied and classified, and how our experiences in interpreting rocks on the Earth have been applied to rocks on the Moon. The lunar samples have provided our only direct information about the Moon’s minerals, chemical composition,...
