Casparian Strip Fortification as a Defense Mechanism to Fusarium oxysporum f. sp. vasinfectum Race 4 Infection in a Highly Resistant Gossypium barbadense Cultivar

Our findings identify a distinct molecular signature of resistance to FOV4 in pima cotton, with Casparian strip reinforcement emerging as a potential mechanism limiting vascular infection. These insights provide a foundation for breeding strategies aimed at improving Fusarium wilt resistance in cotton.
