Research progress on the underlying mechanisms of plant
网页Here, we reviewed the recent research progress on the response mechanisms of six common plant defense enzymes, SOD, CAT, POD, PPO, LOX and PAL, to insect stress, and compared their similarities and disparities.
过氧化物酶（POD）活性测定（愈创木酚法）
网页过氧化物酶（Peroxidase，POD）是一种氧化还原酶，主要存在于植物和真菌中。. 它能够催化过氧化物分解，产生氧气和双氧水，同时也能催化一些酚类物质氧化，生成醌类物质。. 这些物质可以与细胞内的蛋白质、多糖等物质结合，形成褐变产物，影响食品的品质 ...
Antioxidative capacity is highly associated with the storage …
网页2019年7月31日 · The storage roots of the storage-tolerant cultivars maintained higher activities and expression levels of antioxidative enzymes, including ascorbate peroxidase (APX), peroxidase (POD), catalase...
Changes in antioxidant substances and antioxidant enzyme …
网页2023年11月1日 · Superoxide (SOD), catalase (CAT) and peroxidase (POD) play important roles in the antioxidant enzyme system. SOD is the first line of defense against reactive oxygen species (ROS), and its main function is to clear excess O 2− in the cell, a process through which O 2− can be converted into H 2 O 2 ( Sheeba et al., 2011 ).
Differential activity of the antioxidant defence system and …
网页2019年6月12日 · The results showed that the superoxide dismutase (SOD), peroxidase (POD), catalase activity (CAT), hydrogen peroxide content, soluble protein content and soluble sugar content increased with...
网页相应地,为了保护细胞免受ROS 的潜在伤害,植物体发展了一套完整的防御系统, 包括酶促的抗氧化体系(如SOD、CAT、POD 等) 和非酶促抗氧化体系(如AsA、GSH 等)。 然而, 越来越多的证据表明,ROS 不仅只是细胞代谢中有害的副产品,更是细胞信号传导和调控的重要组成部分。 这一发现首先来自于细菌,OxyR蛋白是细菌中的转录调控因子,H2O 2 能氧化OxyR中两个保守的胱氨酸形成二硫键, 通过改变其结构而激活其活性。 大肠杆菌中,SoxR 转录因子能 …
Antioxidant enzymes regulate reactive oxygen species during pod ...
网页2014年2月4日 · The antioxidant enzymes superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) apparently contributed to ROS accumulation in pod wall tissues. Furthermore, specifically SOD and POD were found to be associated with pod growth through the regulation of ROS generation and transformation.
Transcriptome profiling reveals potential genes involved in
网页2021年8月9日 · A total of 8347 differentially expressed genes were identified, of which 62 genes were from six gene families (i.e., PPO, PAL, POD, CAT, APX, and GST) potentially associated with enzymatic...
过氧化物酶（POD）检测 - 知乎 - 知乎专栏
网页过氧化物酶(pod)是植物在逆境条件下酶促防御系统的关键酶之一，与超氧化物歧化酶(sod)、过氧化氢酶(cat)协同作用，清除体内过剩的自由基，从而提高植物的抗逆性。
