Spore germination inhibitors

In addition to its spore germination inhibitor activity, it shows phytohormone (cytokinine) activity. Its derivative without the 3-methylbut-2-enyl residue, 3-(L-3-amino-3-carboxypropyl)-adenine 2, shows the same regulatory function as discadenine. ...

It is assumed that chlorogenic acids in plants possess antiviral properties and the concentration increases after infection. Indeed, chlorogenic acid is an inhibitor of Botrytis spore germination [87], Previously, chlorogenic acid was reported to have antiviral activity [88, 89],... 

The fungicides are very versatile in the contol of fungi that have become resistant to the demethylase inhibitor (DMI) fungicides described later. They have surprisingly low mammalian toxicity, but as with many other respiratory poisons, they show some toxicity to fish and other aquatic organisms. They may also be toxic to earthworms. In fungi they inhibit spore germination. The structures show the natural products strobilurin B and azoxystrobin, which has been marketed since 1996. 

Considerable evidence has been obtained indicating that gramicidin S (GS) is an inhibitor of the phase of spore germination known as outgrowth in B. brevis [ 196,197,199,224,225]. The cumulative observations are as follows ... 

As reported before, oleuropein attacks the cytoplasmic membrane, destroying its permeability and causing outflow of intracellular constituents such as glutamate, potassium and phosphorus. This action is crucial for the spores while the effectiveness of germination inhibitors may depend upon their capability to permeate the spore coat mid may obstruct germination-promoting sites [101]. 

Inhibited by chiral monoterpenes from ponderosa pine resin (e.g.> llmonene, -plnene and 6-phellandrene and a-plnene). The greatest enantiomeric effect Is observed with (+)-a-plnene which Is three times more Inhibitory against Ceratocystls than the (-)-antlpode (42,43). In another study using Plnus radlata monoterpenes, (+)-llmonene was shown to be a potent Inhibitor of Diplodea plnea spore germination while (-)-llmonene was Inactive (44). 

Secondary metabolites from Streptomyces virido-chromogenes. G. B(C H s03,Mr 196.11, yellow solid, mp. 80 °C) inhibits the germination of streptomycetes and plants at low concentrations (40 ng/L). G. B represents the first autoregulative inhibitor of spore germination in streptomycetes. G. A (C,011,403, Mr 182.09, yellow solid, mp. 138 °C) does not possess these activities.
