To investigate the role of vacuolar compartmentalization in Cd accumulation, chelation and induced antioxidation, we quantified the amounts of total cadmium (Cd), Cd2+, glutathione (GSH) and reactive oxygen species (ROS) in leaf...

Author(s): Guangzhe Yang, Shan Fu, Jingjing Huang, Longying Li, Yan Long, Qiuxing Wei, Zhigang Wang, Zhiwei Chen, Jixing Xia Cadmium (Cd) is a highly toxic element to living organisms, and its accumulation in the edible portions of crops poses a potential threat for human health. The molecular mechanisms underlying Cd detoxification and accumulation are not fully understood in plants. In this...

Author(s): Xuejing Wen, Yu Ding, Zilong Tan, Jingxin Wang, Daoyuan Zhang, Yucheng Wang Cadmium (Cd) is one of the most serious global environmental pollutants, which inhibits plant growth and interferes with their physiological processes. However, there have been few studies on the involvement of long noncoding RNAs (lncRNAs) in Cd tolerance. In the present study, we identified the lncRNAs from...

Author(s): Puja Agarwal, Mehali Mitra, Samrat Banerjee, Sujit Roy Here, we describe functional characterization of Arabidopsis thaliana MYB4 transcription factor, a member of R2R3-subfamily of MYB domain protein, in the regulation of Cd-stress tolerance in Arabidopsis. Transgenic Arabidopsis plants overexpressing MYB4 showed appreciable Cd tolerance than wild-type plants, while MYB4 loss of...

Author(s): Shiyu Qin, Hongen Liu, Zed Rengel, Wei Gao, Zhaojun Nie, Chang Li, Mingyang Hou, Jin Cheng, Peng Zhao Various nutrients (Mg, Zn, Fe, Mn, Si, etc.) can supress cadmium (Cd) uptake and alleviate Cd toxicity, but the mechanisms are not the same. In this study, the molecular mechanism governing the effects of boron (B) on uptake of Cd in hydroponically-grown wheat was characterized. As...

Author(s): Carlos Flores-Ortiz, Lilia M. Alvarez, Alejandro Undurraga, Daniela Arias, Felipe Durán, Guillermo Wegener, Claudia StangeAbstractDaucus carota is a biennale crop that develops an edible storage root. Orange carrots, the most consumed cultivar worldwide, accumulate high levels of β-carotene and α-carotene in the storage root during secondary growth. Genes involved in β-carotene...

Spaink, Andreas RoussisAbstractPhospholipase PLA1-Iγ2 or otherwise DAD1-LIKE LIPASE 3 (DALL3) is a member of class I phospholipases and has a role in JA biosynthesis. AtDALL3 was previously identified in a yeast two-...

Author(s): Shin-ichi Nakamura, Nobuo Suzui, Yong-Gen Yin, Satomi Ishii, Shu Fujimaki, Naoki Kawachi, Hiroki Rai, Takashi Matsumoto, Kanna Izawa-Sato, Naoko Ohkama-OhtsuAbstractGlutathione (GSH) is a thiol-containing compound involved in many aspects of plant metabolism. In the present study, we investigated how enhancing endogenous and exogenous GSH affects cadmium (Cd) movement and distribution...

Author(s): Alexandre Perochon, Zsolt Váry, Keshav B. Malla, Nigel G. Halford, Matthew J. Paul, Fiona M. DoohanAbstractDeoxynivalenol (DON) is a mycotoxin produced by phytopathogenic Fusarium fungi in cereal grain and plays a role as a disease virulence factor. TaFROG (Triticum aestivum Fusarium Resistance Orphan Gene) enhances wheat resistance to DON and it interacts with a sucrose non-fermenting...

Author(s): Jie Zhang, Liang Li, Liping Huang, Manman Zhang, Ziyan Chen, Qingsong Zheng, Haiyan Zhao, Xi Chen, Mingyi Jiang, Mingpu TanAbstractThe plant-specific NAC transcription factors play diverse roles in various stress signaling. Alternative splicing is particularly prevalent in plants under stress. However, the investigation of cadmium (Cd) on the differential expression of the splice...

Author(s): Yanfeng Hu, Jia You, Chunjie Li, Fengjuan Pan, Congli WangAbstractSoybean cyst nematode (Heterodera glycines Ichinohe) is a sedentary root endoparasite that causes serious yield losses on soybean (Glycine max) worldwide. H. glycines secrets effector proteins into host cells to facilitate the success of parasitism. Nowadays, a large number of candidate effectors were identified from the...
