Description:

Prehelminthosporol is a phytotoxin, it may play an important role in pathogenesis by killing or weakening plant cells in advance of the growing hyphae and facilitating nutrient uptake and further growth of the fungus in plant tissue.

Targets:

Antifection

Effect of prehelminthosporol, a phytotoxin produced by Bipolaris sorokiniana, on barley roots.[Reference: WebLink]

METHODS AND RESULTS:
The effects of Prehelminthosporol, a toxin produced by Bipolaris sorokiniana, were investigated on barley roots. A concentration of 30 μg∙mL−1 Prehelminthosporol or higher in nutrient solution significantly increased the rate of nuclear disintegration in the root cortex cells. The toxin also increased leakage of ATP from intact roots of barley seedlings grown in nutrient solution, but the growth rate of the seedlings was not significantly affected. However, diluted filtrate from liquid shake cultures of the fungus inhibited the growth of the seedlings by 21 – 73% over a 5-day period.
CONCLUSIONS:
The results indicate that the toxin may play an important role in pathogenesis by killing or weakening plant cells in advance of the growing hyphae and facilitating nutrient uptake and further growth of the fungus in plant tissue. Different cultivars of barley differed in sensitivity to Prehelminthosporol, but sensitivities were not correlated with known levels of resistance to B. sorokiniana.

Prehelminthosporol Description

Source:	The cultures of Bipolaris sorokiniana.
Solvent:	Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage:	Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C). Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour. Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com
After receiving:	The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
