Interactions between ethylene, gibberellins, and brassinosteroids in the development of rhizobial and mycorrhizal symbioses of pea.
The regulation of arbuscular mycorrhizal development and nodulation involves complex interactions between the plant and its microbial symbionts. In this study, we use the recently identified ethylene-insensitive ein2 mutant in pea (Pisum sativum L.) to explore the role of ethylene in the development of these symbioses. We show that ethylene acts as a strong negative regulator of nodulation, con...
متن کاملFurther identification of endogenous gibberellins in the shoots of pea, line g2.
To interpret the metabolism of radiolabeled gibberellins A(12)-aldehyde and A(12) in shoots of pea (Pisum sativum L.), the identity of the radiolabeled peaks has to be determined and the endogenous presence of the gibberellins demonstrated. High specific activity [(14)C]GA(12) and [(14)C]GA(12)-aldehyde were synthesized using a pumpkin endosperm enzyme preparation, and purified by high performa...
متن کاملGibberellins
What are they? The gibberellins make up a family of small organic compounds derived from a common 20-carbon precursor. They regulate growth and development in plants and their chemical structure superficially resembles that of steroid hormones. So far, more than 100 gibberellins have been identified. Fortunately, any one plant species produces only a few of the known gibberellins. Furthermore, ...

fixity — the behavior of fossil organisms will be similar to the behavior of their extant descendants at the generic level — my wife and I re-constructed the type of Tertiary forest that existed in Hispaniola based on plants and animals in Dominican amber. We concluded that the amber forest in Hispaniola was similar to today’s tropical moist forest, but was much more diverse and contained a num...
متن کاملReversal of the Light Inhibition of Pea Stem Growth by the Gibberellins.
when inactive, denatured, virus RNA is incorporated into a reconstituted nucleoprotein. It should be emphasized that the present data do not, in our opinion, permit a choice between the foregoing alternative explanations. The possibility that small amounts of otherwise inactive virus RNA components may, when incorporated into DNA-bearing nucleoproteins, render the polymer infectious is subject ...
