Herbivore feeding preference corroborates optimal defense theory for specialized metabolites within plants.

Numerous plants protect themselves from attackers by using specialized metabolites. The biosynthesis of these deterrent, often toxic metabolites is costly, as their synthesis diverts energy and resources on account of growth and development. How plants diversify investments into growth and defense is explained by the optimal defense theory.

The GORKY glycoalkaloid transporter is indispensable for preventing tomato bitterness.

Fruit taste is determined by sugars, acids and in some species, bitter chemicals. Attraction of seed-dispersing organisms in nature and breeding for consumer preferences requires reduced fruit bitterness. A key metabolic shift during ripening prevents tomato fruit bitterness by eliminating α-tomatine, a renowned defence-associated Solanum alkaloid.

Design and Direct Assembly of Synthesized Uracil-containing Non-clonal DNA Fragments into Vectors by USER Cloning.

This protocol describes how to order and directly assemble uracil-containing non-clonal DNA fragments by uracil excision based cloning (USER cloning). The protocol was generated with the goal of making synthesized non-clonal DNA fragments directly compatible with USER cloning. The protocol is highly efficient and would be compatible with uracil-containing non-clonal DNA fragments obtained from any synthesizing company.
