- Intervention effect Phytophthora infection reduced root length, shoot length and leaf number in susceptible ICPL 11260 by 0.5- to 2-fold compared with non-infected controls.
- Intervention effect Phytophthora infection reduced fresh weight and dry weight in susceptible ICPL 11260 by 0.5- to 2-fold compared with non-infected controls.
- Observation Infected ICPL 11260 plants showed pronounced cellular damage and mycelial invasion by 30 days after infection.
- Observation Infected resistant IPAC-02 plants exhibited no fungal colonization.
- Observation Under P. cajani stress, resistant IPAC-02 maintained significantly elevated total sugars (153.7 mg g-1 FW) compared with susceptible ICPL 11260.
- Observation Under P. cajani stress, resistant IPAC-02 maintained significantly elevated proteins (25.4 mg g-1 FW) compared with susceptible ICPL 11260.
- Observation Under P. cajani stress, resistant IPAC-02 maintained significantly elevated phenols (51.7 mg g-1 FW) compared with susceptible ICPL 11260.
- Observation Under P. cajani stress, resistant IPAC-02 maintained significantly elevated flavonoids (33.1 mg g-1 FW) compared with susceptible ICPL 11260.
- Observation Under P. cajani stress, resistant IPAC-02 showed elevated beta-1,3-glucanase activity (9.1 U mg-1 protein) compared with susceptible ICPL 11260.
- Mechanism The biochemical responses support a lignification-mediated defense mechanism in IPAC-02.
- Recommendation IPAC-02 has potential value for breeding Phytophthora-resistant pigeon pea cultivars.
