Structural investigations of N-carbamoylputrescine amidohydrolase from Medicago truncatula: insights into the ultimate step of putrescine biosynthesis in plants

Frontiers in Plant Science, 2016
Putrescine, 1,4-diaminobutane, is an intermediate in the biosynthesis of more complexed polyamines, spermidine and spermine. Unlike other eukaryotes, plants have evolved a multistep pathway for putrescine biosynthesis that utilizes arginine. In the final

Convergence and parallelism in the evolution of plant metabolism

Journal of Integrative Plant Biology, EarlyView.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

Auxin‐Induced Nicotine Inhibition Is Mediated by NaARF5 Through the Suppression of NaERF1‐Like Expression and Interaction With NaERF1‐Like in Nicotiana attenuata

Plant Biotechnology Journal, EarlyView.
ABSTRACT Nicotine is the most abundant alkaloid produced by Nicotiana species against insect herbivores. Although it has been known for decades that auxin can strongly inhibit nicotine biosynthesis, the underlying mechanisms have remained unclear.

Postharvest physiological responses of pomegranate fruit (cv. Wonderful) to exogenous putrescine treatment and effects on physico-chemical and phytochemical properties

Food Science and Human Wellness, 2020
Pomegranate fruit (cv. Wonderful) were treated with putrescine (1, 2 and 3 mmol/L) before storage for 4 months at 5 °C and 95 % RH and the effects on postharvest life and quality attributes were studied.

Effects of putrescine and low temperature on the apoplastic antioxidant enzymes in the leaves of two wheat cultivars

Plant, Soil and Environment, 2009
The effects of putrescine (a polyamine), low temperature and their combinations on the activities of apoplastic antioxidant enzymes were studied in the leaves of two wheat cultivars, winter (Dogu-88) and spring (Gerek-79). Fifteen-day-old wheat seedlings

The MdICE1/MdFAMA‐MdTYDC Transcriptional Module Confers Cold Tolerance by Regulating Dopamine Metabolism in Apple

Plant Biotechnology Journal, EarlyView.
ABSTRACT Low temperature is a critical abiotic stress that imposes major constraints on the sustainable development of the fruit tree industry. Although exogenous dopamine has been shown to enhance cold tolerance in plants, its molecular mechanisms in apple (Malus domestica) remain poorly understood.

Putrescine priming effects on chlorophyll fluorescence, antioxidant enzyme activity, and primary metabolite accumulation in maize seedlings under water deficit

Biologia Plantarum
This study aimed to evaluate the effect of putrescine priming on the initial growth, chlorophyll fluorescence, primary metabolites accumulation, and antioxidant enzyme activities in two maize hybrids with contrasting drought tolerances. Seeds of Zea mays

Pre-storage putrescine treatment maintains quality and prolongs postharvest life of Musa acuminata L.

Advances in Horticultural Science, 2017
The study was carried out to determine the effect of putrescine on quality and postharvest life of Musa acuminata L. during storage. The fruits were dipped at different concentrations of putrescine (0.5, 1 and 2 mM for 30 min) and distilled water as ...

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, EarlyView.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

Natural Variations in the Activity of Hydroxycinnamoyl Transferases Promote Accumulation of Metabolites Conferring Rice Resistance

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant‐derived secondary metabolites act as regulators of in planta defence. Plant phenylpropanoid metabolic compounds, including final metabolites such as lignin and flavonoids, and a few intermediate metabolites play critical roles in defence.
