Trehalose: A mycogenic cell wall elicitor elicit resistance against leaf spot disease of broccoli and acts as a plant growth regulator

Abstract

Highlights Mycogenic cell wall elicitor was isolated from trichoderma atroviride . The isolated elicitor was identified as trehalose by LC-MS analysis. Seed priming with elicitor enhanced early germination and vigour. Primed plants induced resistance against leaf spot disease of brocolli. Trehalose sugar act as a bio-stimulant for growth promotion and plant defence.

Editorial: Biological and biotechnological applications of natural bioactives

“…A study by Britto et al. [6] states that trehalose, a biogenic cell-wall elicitor obtained from Trichoderma atroviride (TaCWE) showed significant induced disease resistance against leaf spot disease caused by A. brassicicola and plant growth promotion in the broccoli plants. Chondroitin sulfate (CS) is the most abundant glycosaminoglycan that has been produced from microbial fermentation of engineered microbial strains to improve CS yields in different hosts and is used for a wide range of applications, especially as a supplement for the treatment of osteoarthritis diseases [7] .…”

In vitro assembly of the trehalose bi-enzyme complex with artificial scaffold protein

“…In nature, trehalose is a non-reducing disaccharide that is linked to the glucose residue by an α-1,1 glycoside bond ( Trevelyan and Harrison, 1956 ; Mery et al, 2022 ). It is an excellent natural desiccant and preservative, as well as a new functional oligosaccharide ( De Britto et al, 2021 ). Trehalose will form a unique protective membrane on the cell surface, effectively protecting the invariant inactivation of protein molecules, to maintain the normal life process and biological characteristics of living organisms in harsh environments characterized by high temperature, high cold, high osmotic pressure, and dry water loss ( Camisasca et al, 2020 ; Chen et al, 2022 ).…”

“…Enzyme conversion is presently the most potent method for the production of trehalose, which mainly uses maltose, glucose, starch, and dextrin as substrates and trehalose synthesis-related enzymes to produce trehalose. So far, there are five biosynthetic pathways of trehalose ( De Britto et al, 2021 ). At present, the primary method of large-scale production of trehalose at home and abroad is to prepare trehalose by using the mixed catalytic starch liquefaction solution of maltooligosyltrehalose synthase (MTSase) and maltooligosyltrehalose trehalohydrolase (MTHase).…”
