QTL analysis reveals the effect of CER1-1 and CER1-3 to reduce fruit water loss by increasing cuticular wax alkanes in citrus fruit

Hongbin Yang, Yunqian Zou, Xin Li, Mingfei Zhang, Zhifeng Zhu, Rangwei Xu, Juan Xu, Xiuxin Deng, Yunjiang Cheng

Summary: Postharvest water loss can affect fruit quality, and the study found that alkanes in cuticular wax may play an important role in limiting fruit water loss. Candidate genes CER1-1 and CER1-3 were identified as potentially involved in alkane synthesis, and heterologous expression in Arabidopsis confirmed their role in reducing leaf water loss. Coating with C28 alkane could reduce postharvest fruit water loss, providing new insights for developing coating agents and breeding citrus varieties with better storage performance.

Insights into the molecular basis of biocontrol of Botrytis cinerea by Clonostachys rosea in tomato

Fanyue Meng, Rui Lv, Mozhen Cheng, Fulei Mo, Nian Zhang, Haonan Qi, Jiayin Liu, Xiuling Chen, Yuxin Liu, Hossein Ghanizadeh, Aoxue Wang

Summary: The study revealed that treatment with C. rosea can enhance tomato resistance to B. cinerea by increasing the expression of genes and proteins related to oxidation-reduction reactions and defense-related enzymes. The activation of peroxisome-related enzymes and proteins associated with the AsA-GSH cycle pathways can scavenge ROS and maintain the ROS balance in cells, while enzymes associated with the phenylpropanoid pathway can synthesize metabolites that inhibit the establishment of invading pathogens in the host. The findings provide insights into the molecular basis of B. cinerea resistance induced by C. rosea and shed light on detailed regulatory pathways associated with resistance.
