Sesbania virgata (Cav.) Pers (wand riverhemp) is a fast-growing tropical legume species that has been used for revegetation of riparian forests and rehabilitation of degraded areas and that exhibits an invasive behavior in certain regions of Brazil. Preliminary studies have shown that seed leachates

When applied to the roots of Arabidopsis thaliana, the phytotoxin (±)-catechin triggers a wave of reactive oxygen species (ROS), leading to a cascade of genome-wide changes in gene expression and, ultimately, death of the root system. Biochemical links describing the root secreted phytotoxin,

Research indicates that the invasiveness of Centaurea stoebe is attributed to the stronger allelopathic effects on the native North American species than on the related European species, which is one of the unquestionable aspects of the "novel weapons hypothesis (NWH)." Studies originating from
Overexpression of a glycosyltransferase gene SrUGT74G1 from Stevia improved growth and yield of transgenic Arabidopsis by catechin accumulation.

Steviol glycoside and gibberellin biosynthetic routes are known as divergent branches of a common origin in Stevia. A UDP-glycosyltransferase encoded by SrUGT74G1 catalyses the conversion of steviolbioside into stevioside in Stevia rebaudiana leaves. In the present study, transgenic Arabidopsis
AtHB2, a class II HD-ZIP protein, negatively regulates the expression of CsANS, which encodes a key enzyme in Camellia sinensis catechin biosynthesis.

Tea (Camellia sinensis) is an important cash crop that is beneficial to human health due to its remarkable content of catechins. The biosynthesis of catechins follows the flavonoid pathway, which is highly branched. Among the enzymes involved in catechin biosynthesis, anthocyanidin synthase (CsANS)

BACKGROUND
Multi-monocistronic and multi-variate vectors were designed, built, and tested for the improved production of cyanidin 3-O-glucoside (C3G) in Escherichia coli BL21 (DE3). The synthetic bio-parts were designed in such a way that multiple genes can be assembled using theOxalate contributes to the resistance of Gaillardia grandiflora and Lupinus sericeus to a phytotoxin produced by Centaurea maculosa.

Centaurea maculosa Lam. is a noxious weed in western North America that produces a phytotoxin, (+/-)-catechin, which is thought to contribute to its invasiveness. Areas invaded by C. maculosa often result in monocultures of the weed, however; in some areas, North American natives stand their ground

Anthocyanidin reductase (ANR), encoded by the BANYULS gene, is a newly discovered enzyme of the flavonoid pathway involved in the biosynthesis of condensed tannins. ANR functions immediately downstream of anthocyanidin synthase to convert anthocyanidins into the corresponding 2,3-cis-flavan-3-ols.

The occurrence of plant hormesis is a poorly understood phenomenon, wherein low doses of phytotoxins unusually promote growth responses in higher plants. In contrast, negative plant-plant interactions mediated through secreted small molecular weight compounds initiate growth inhibitory responses.

BACKGROUND
Anthocyanins are a class of brightly colored, glycosylated flavonoid pigments that imbue their flower and fruit host tissues with hues of predominantly red, orange, purple, and blue. Although all anthocyanins exhibit pH-responsive photochemical changes, distinct structural decorations on

Recent studies on the biosynthesis of proanthocyandins have identified key genes and enzymes in the formation of 2,3-cis-flavan-3-ols (epiafzelechin, epicatechin, and epigallocatechin). However, the enzymes that catalyze the polymerization of monomer units remain unknown. Studies of proanthocyanidin

Proanthocyanidins (PAs) are mainly composed of epicatechin (EC) or catechin (C) subunits. C-type catechins (C and GC) are generally considered to be catalyzed by Leucocyanidin reductase (LAR). In this study, we re-evaluated the function of LAR. LcLAR1 was isolated from Lotus corniculatus that is
