Partial alleviation of oxidative stress induced by gamma irradiation in Vigna radiata by polyamine treatment.
TLDR
This study shows that treatment with putrescine can partially alleviate oxidative damage caused by gamma rays as observed in an important pulse crop Vigna radiata (L.) Wilczek or mung bean.Abstract:
Purpose: Environmental changes generate free radicals and reactive oxygen species (ROS) resulting in abiotic stress in plants. This causes alterations in germination, morphology, growth and develop...read more

Polyamines, metallothioneins, and phytochelatins—Natural defense of plants to mitigate heavy metals
TL;DR: The effect of two essential and two nonessential heavy metals—copper, zinc, and cadmium and lead, respectively, and their effects on plants in general are discussed and downregulations in the expression of metallothionein type 2 gene are observed.

Grafting Watermelon Onto Pumpkin Increases Chilling Tolerance by Up Regulating Arginine Decarboxylase to Increase Putrescine Biosynthesis
TL;DR: In this paper , the authors showed that grafting of watermelon onto pumpkin rootstock led to the notable accumulation of putrescine in watermelon seedlings under chilling conditions.

Physiological consequences of gamma ray irradiation in tall fescue with elimination potential of Epichloë fungal endophyte.
TL;DR: In this paper, the growth and physiological parameters associated with plant tolerance to oxidative stress of host plants, as well as endophytic infection frequency (% of plants infected) and intensity (mean number of endophyte hyphae per the field of view), were examined in 3 months-old seedlings.

Analysis of relative gene expression data using real-time quantitative pcr and the 2(-delta delta c(t)) method
TL;DR: The 2-Delta Delta C(T) method as mentioned in this paper was proposed to analyze the relative changes in gene expression from real-time quantitative PCR experiments, and it has been shown to be useful in the analysis of realtime, quantitative PCR data.
