Long-distance transport of endogenous gibberellins in Arabidopsis.
Gibberellins (GAs) are phytohormones controlling major aspects of plant growth and development. Although previous studies suggested the existence of a transport of GAs in plants, the nature and properties associated with this transport were unknown. We recently showed through micrografting and biochemical approaches that the GA12 precursor is the chemical form of GA undergoing long-distance tra...
متن کاملLong-distance phloem transport of glucosinolates in Arabidopsis.
Glucosinolates are a large group of plant secondary metabolites found mainly in the order Capparales, which includes a large number of economically important Brassica crops and the model plant Arabidopsis. In the present study, several lines of evidence are provided for phloem transport of glucosinolates in Arabidopsis. When radiolabeled p-hydroxybenzylglucosinolate (p-OHBG) and sucrose were co...
متن کاملLong distance transport.
A few years ago, I attended a 1-day symposium on long distance transport at a national meeting in a country abroad. Towards the end of the day, as the participants became tired and no general agreement was in sight, one observer from an allied discipline remarked, "Why can't you translocation workers make any progress, you still discuss the same miserable old models that were proposed 40 years ...
متن کاملGibberellins control fruit patterning in Arabidopsis thaliana.
The Arabidopsis basic helix-loop-helix (bHLH) proteins INDEHISCENT (IND) and ALCATRAZ (ALC) specify tissues required for fruit opening that have major roles in seed dispersal and plant domestication. Here, we show that synthesis of the phytohormone gibberellin is a direct and necessary target of IND, and that ALC interacts directly with DELLA repressors, which antagonize ALC function but are de...
متن کاملIntegration of biosynthesis and long-distance transport establish organ-specific glucosinolate profiles in vegetative Arabidopsis.
Although it is essential for plant survival to synthesize and transport defense compounds, little is known about the coordination of these processes. Here, we investigate the above- and belowground source-sink relationship of the defense compounds glucosinolates in vegetative Arabidopsis thaliana. In vivo feeding experiments demonstrate that the glucosinolate transporters1 and 2 (GTR1 and GTR2)...
