|a Alternative pathway (AP) plays essential roles in plant adaptation to environmental stress. However, the exact role of AP in response to aluminum (Al) toxicity remains elusive. We here provide solid evidences that the activated AP capacity in root tips of soybean alleviated Al toxicity. Furthermore, inhibition of AP by pharmacological or transgenic approach aggravated Al-induced programmed cell death (PCD) occurrence mediated through reactive oxygen species (ROS)-dependent mitochondrial pathway. Our results also demonstrated that nitric oxide (NO) plays a negative role in PCD occurrence caused by Al in soybean root tips. Interestingly, the alleviating effect of NO on Al-induced PCD could be blocked by AP inhibition. Further investigation showed that NO mediates the induction of AP resulting from the upregulation of AOX expression and pyruvate content in Al-treated root tips of soybean. Taken together, our results clearly suggest that AP participates in the alleviation of Al toxicity and also plays a critical role in the alleviating effect of NO on Al-induced PCD occurrence, which will open up new avenues for the improvement of plant growth in acidic soils
