Stress and defense responses in plant secondary metabolites production

Biological Research, Journal Year: 2019, Volume and Issue: 52(1)

Published: July 29, 2019

In the growth condition(s) of plants, numerous secondary metabolites (SMs) are produced by them to serve variety cellular functions essential for physiological processes, and recent increasing evidences have implicated stress defense response signaling in their production. The type concentration(s) molecule(s) a plant determined species, genotype, physiology, developmental stage environmental factors during growth. This suggests adaptive responses employed various taxonomic groups coping with defensive stimuli. past decades had witnessed renewed interest study abiotic that influence metabolism vitro vivo plants. Application molecular biology tools techniques facilitating understanding processes pathways involved SMs production at subcellular, cellular, organ whole systems growth, application metabolic engineering biosynthetic intermediates.

The scaffold-forming steps of plant alkaloid biosynthesis

Natural Product Reports, Journal Year: 2020, Volume and Issue: 38(1), P. 103 - 129

Published: Aug. 3, 2020

Alkaloids from plants are characterised by structural diversity and bioactivity, maintain a privileged position in both modern traditional medicines. In recent years, there have been significant advances elucidating the biosynthetic origins of plant alkaloids. this review, I will describe progress made determining metabolic so-called true alkaloids, specialised metabolites derived amino acids containing nitrogen heterocycle. By identifying key steps that feature majority pathways, highlight roles played modifications to primary metabolism, iminium reactivity spontaneous reactions molecular evolutionary these pathways.

Regulation Mechanism of Plant Pigments Biosynthesis: Anthocyanins, Carotenoids, and Betalains

Metabolites, Journal Year: 2022, Volume and Issue: 12(9), P. 871 - 871

Published: Sept. 16, 2022

Anthocyanins, carotenoids, and betalains are known as the three major pigments in plant kingdom. Anthocyanins flavonoids derived from phenylpropanoid pathway. They undergo acylation glycosylation cytoplasm to produce anthocyanin derivatives deposits cytoplasm. Anthocyanin biosynthesis is regulated by MBW (comprised R2R3-MYB, basic helix-loop-helix (bHLH) WD40) complex. Carotenoids fat-soluble terpenoids whose synthetic genes also As precursors for synthesis of hormones nutrients, carotenoids not only synthesized plants, but some fungi bacteria, play an important role photosynthesis. Betalains special water-soluble that exist Caryophyllaceae plants. Compared anthocyanins regulation mechanism simpler, starting tyrosine, MYB (myeloblastosis). Recently, a considerable amount novel information has been gathered on pigment biosynthesis, specifically with respect aspects. In this review, we summarize knowledge current gaps our understanding view highlighting opportunities development pigment-rich

Betalains in Some Species of the Amaranthaceae Family: A Review

Antioxidants, Journal Year: 2018, Volume and Issue: 7(4), P. 53 - 53

Published: April 4, 2018

Natural pigments are largely distributed in the plant kingdom. They belong to diverse groups, with distinct biochemical pathways. Betalains colours that range from yellow red-violet can de divided into two main subgroups: betaxanthins and betacyanins. These types of confined 13 families order Caryophyllales some genera higher fungi (Amanita muscaria, Hygrocybe Hygrophorus). The Amaranthaceae family includes which betalains present: Alternanthera, Amaranthus, Beta, Chenopodium, Celosia Gomphrena. biosynthesis their general biological properties were reviwed present work.
