Plant growth regulation inhibitors

HydroxyethyUiydrazine (11) is a plant growth regulator. It is also used to make a coccidiostat, furazoHdone, and has been proposed, as has (14), as a stabilizer in the polymerization of acrylonitrile (72,73). With excess epoxide, polysubstitution occurs and polyol chains can form to give poly(hydroxyaLkyl) hydrazines which have been patented for the preparation of cellular polyurethanes (74) and as corrosion inhibitors for hydrauHc fluids (qv) (75). DialkyUiydrazines, R2NNH2, and alkylene oxides form the very reactive amineimines (15) which react further with esters to yield aminimides (16) ... 

The orsellinic acid derivative lasiodiplodin 84 and its de-O-methyl congener are found, i.a., in the roots of Arnebia euchroma, a plant which is used in traditional Chinese medicine. These compounds elicit diverse biological responses as inhibitors of prostaglandin biosynthesis, cyctotoxic agents, and plant growth regulators.

Efforts may now have been successful Whereas normal tobacco cells require auxin for division, sequence tagged (TDNA) lines encoding an adenylyl cyclase were obtained which were auxin-independent but cAMP-dependent. From one line (axi 141), a complementary DNA encoding adenylyl cyclase has been isolated with characteristic leucine repeats and similarity to yeast adenylyl cyclase (Ichikawa et al., 1997). The result seems not to be the expression of an alternative division pathway from the normal auxin-driven division since it is blocked by auxin inhibitors and is activated by cAMP and the cyclase activator forskolin. Perhaps a link to G-protein at the membrane will now bring plant growth regulation even closer to that of animals. 

Xenoblotics can alter various metabolic pathways In plants. Chemical alteration of phenolic compounds for agricultural purposes has been suggested to have potential (130. 131). Since several major plant enzymes of secondary metabolism are Involved In resistance to pathogens, alteration of secondary metabolism could Influence disease development. Herbicides, plant growth regulators (synthetic and natural), and enzyme Inhibitors such as those presented for PAL (Fig. 

Many substituted imidazoles are known as inhibitors of P38 MAP kinase, fungicides and herbicides, plant growth regulators, and therapeutic agents [3]. 

Cyclohexamide is used as a fungicide, plant growth regulator, and as protein synthesis inhibitor. This is also used in laboratory media as a selective agent to permit isolation of pathogenic and nonpathogenic fungi.
