Plants* shouldn't have to repel fungal pathogens, but when they do, it's nice to know OXI1's working for them. OXI1 is the kinase that fights back,™ by switching on the plant's natural defenses to repel would-be invaders. That's why OXI1 is the kinase plants depend on when danger strikes.  
Through a patented mechanism, OXI1 leaps into action at the first sign of attack, leveraging the lethal force of powerful oxidative bursts that the plant unleashes on would-be invaders, stopping pathogens in their tracks!

And that's not all... OXI1 has also been shown to improve root hair growth, so your plants will be stronger and healthier, even when they're not under attack!

*OXI1 is only available in Arabidopsis thaliana.
