Low R:FR light ratio enhances calcium nitrate resistance and stomatal movement in tomato seedlings by regulating H2O2 accumulation Horticult. Plant J. (IF 5.7) Pub Date : 2023-10-31 Xiaoting Zhou, Deyang Ye, Yunxin Tang, Yirong Gan, Jia Huang, Zhonghua Bian, Lihong Su, Zhongqun He, Chaoxing He, Shaobo Cheng
Secondary salinization is a major environmental factor that causes a stress response and growth inhibition in plants in protected agriculture. The positive effect of a low red to far-red light ratio (R:FR) in salt tolerance through antioxidant defense has been reported, while the underlying model remains obscure. In this study, we used physiological and genetic approaches to investigate the relationship

Genome assembly of the plant pathogen Plasmodiophora brassicae reveals novel secreted proteins contributing to the infection of Brassica rapa Horticult. Plant J. (IF 5.7) Pub Date : 2023-10-27 Peirong Li, Sirui Lv, Zhijun Zhang, Tongbing Su, Weihong Wang, Xiaoyun Xin, Xiuyun Zhao, Xiaoman Li, Deshuang Zhang, Yangjun Yu, Tao Ma, Guodong Liu, Fenglan Zhang, Shuancang Yu
The soil-resident pathogen, Plasmodiophora brassicae, infects cruciferous crops, causing obligate parasitic clubroot disease and posing a significant threat to the Brassica vegetable industry in China. To learn more about its pathogenesis, we reported a Nanopore sequencing-derived 25.3 Mb high-quality genome sequence of P. brassicae pathotype 4 strain (P.b 4). Comparing the P.b 4 genome with that of

Mutation in the Agrobacterium hisI gene enhances transient expression in pepper Horticult. Plant J. (IF 5.7) Pub Date : 2023-10-19 Dan Liu, Shengnan Zhao, Jubin Wang, Xi Zhang, Yingtian Deng, Feng Li
Agrobacterium-mediated plant transformation is widely used in plant genetic engineering. However, its efficiency is limited by plant immunity against Agrobacterium. Chili pepper (Capsicum annuum L.) is an important vegetable that is recalcitrant to Agrobacterium-mediated transformation. In this work, Agrobacterium was found to induce a strong immune response in pepper, which might be the reason for
