Putrescine: A Key Metabolite Involved in Plant Development, Tolerance and Resistance Responses to Stress

TLDR
The recent advances in understanding the role of this metabolite in plant growth promotion and protection against abiotic and biotic stresses will be discussed to provide an overview for future research.

Ornithine decarboxylase transgene in tobacco affects polyamines,in vitro-morphogenesis and response to salt stress

Summary Transgenic tobacco plants expressing the putrescine synthesis gene ornithine decarboxylase from mouse were raised to study the effects of up-regulation of a metabolic pathway as critical as

Putrescine Depletion Affects Arabidopsis Root Meristem Size by Modulating Auxin and Cytokinin Signaling and ROS Accumulation

TLDR
PA levels were modified by progressively reducing ADC1/2 activity and Put levels, and changes in root meristematic zone (MZ) size, ROS, and auxin and cytokinin (CK) signaling were investigated, suggesting that PAs modulate MZ size through both hormone signaling and ROS accumulation in Arabidopsis.

Modulation of the polyamine biosynthetic pathway in transgenic rice confers tolerance to drought stress.

TLDR
It is demonstrated clearly that the manipulation of polyamine biosynthesis in plants can produce drought-tolerant germplasm, and a model consistent with the role of polyamines in the protection of plants against abiotic stress is proposed.

Proteomic and Physiological Analyses Reveal Putrescine Responses in Roots of Cucumber Stressed by NaCl

Soil salinity is a major environmental constraint that threatens agricultural productivity. Different strategies have been developed to improve crop salt tolerance, among which the effects of

Differential gene expression of ARGININE DECARBOXYLASE ADC1 and ADC2 in Arabidopsis thaliana: characterization of transcriptional regulation during seed germination and seedling development.

TLDR
In situations of seed germination, root development and response to chilling, the modifications of promoter activities were associated with changes in mRNA levels, emphasizing the involvement of transcriptional regulation in ARGININE DECARBOXYLASE gene expression.

Nickel Accumulation in Rape Shoots (Brassica napus L.) Increased by Putrescine

TLDR
Application of exogenous putrescine (Put) increases nickel accumulation in rape shoots (Brassica napus), improving potential for phytoremediation of contaminated soils and suggesting activation of long-distance metal transport within the plant and reduction of its toxicity due to Put chelating action.
