Journal ArticleDOI
Simultaneous overexpression of both CuZn superoxide dismutase and ascorbate peroxidase in transgenic tall fescue plants confers increased tolerance to a wide range of abiotic stresses.
Sang Hoon Lee,Nagib Ahsan,Nagib Ahsan,Ki-Won Lee,Do-Hyun Kim,Dong-Gi Lee,Sang-Soo Kwak,Suk-Yoon Kwon,Tae-Hwan Kim,Byung-Hyun Lee +9 more
TL;DR: It is concluded that one of the mechanisms of increased anti-oxidative defense in transgenic tall fescue plants is overexpression of the CuZnSOD and APX genes, which are utilized in scavenging ROS and thus provide improved tolerance to abiotic stresses.
Journal ArticleDOI
A proteomic approach in analyzing heat-responsive proteins in rice leaves.
Dong-Gi Lee,Nagib Ahsan,Sang Hoon Lee,Kyu Young Kang,Jeong Dong Bahk,In-Jung Lee,Byung-Hyun Lee +6 more
TL;DR: The results of the present study show that a group of low molecular small heat shock proteins (sHSPs) were newly induced by heat stress, and a low molecular weight mitochondrial (Mt) sHSP was validated further by Western blot analysis.
Journal ArticleDOI
Excess copper induced physiological and proteomic changes in germinating rice seeds
Nagib Ahsan,Dong-Gi Lee,Sang Hoon Lee,Kyu Young Kang,Jeung Joo Lee,Pil Joo Kim,Ho-Sung Yoon,Jong-Sang Kim,Byung-Hyun Lee +8 more
TL;DR: Down-regulation of key metabolic enzymes like alpha-amylase or enolase revealed that the inhibition of seed germinations after exposure to excess copper not only affects starvation in water uptake by seeds but also results in failure in the reserve mobilization processes.
Journal ArticleDOI
Comparative proteomic study of arsenic‐induced differentially expressed proteins in rice roots reveals glutathione plays a central role during As stress
Nagib Ahsan,Dong-Gi Lee,Iftekhar Alam,Pil Joo Kim,Jeung Joo Lee,Young-Ock Ahn,Sang-Soo Kwak,In-Jung Lee,Jeong Dong Bahk,Kyu Young Kang,Jenny Renaut,Setsuko Komatsu,Byung-Hyun Lee +12 more
TL;DR: Comparative proteomic analysis of rice roots during As stress suggests that SAMS, CS, GSTs, and GR presumably work synchronously wherein GSH plays a central role in protecting cells against As stress.
Journal ArticleDOI
Recent developments in the application of proteomics to the analysis of plant responses to heavy metals
TL;DR: This review focuses on recent developments in the applications of proteomics to the analysis of the responses of plants to heavy metals; such studies provide a deeper understanding of protein responses and the interactions among the possible pathways that are involved in detoxification of toxic metals in plant cells.
