A target enrichment probe set for resolving phylogenetic relationships in the coffee family, Rubiaceae. [PDF]

open access: yesAppl Plant Sci, 2023
Abstract Premise Rubiaceae is among the most species‐rich plant families, as well as one of the most morphologically and geographically diverse. Currently available phylogenies have mostly relied on few genomic and plastid loci, as opposed to large‐scale genomic data.

Is a metabolic enzyme complex involved in the efficient and accurate control of Ipecac alkaloid biosynthesis in Psychotria ipecacuanha? [PDF]

open access: yesPlant Signaling and Behavior, 2010
Ipecac alkaloids produced in the medicinal plant Psychotria ipecacuanha such as emetine and cephaeline possess a monoterpenoid-tetrahydroisoquinoline skeleton, which is formed by condensation of dopamine and secologanin. The condensation products are deglucosylated, and the resulting aglycon is further processed to protoemetine, which is condensed with

Three New O-Methyltransferases Are Sufficient for All O-Methylation Reactions of Ipecac Alkaloid Biosynthesis in Root Culture of Psychotria ipecacuanha [PDF]

open access: yesJournal of Biological Chemistry, 2010
The medicinal plant Psychotria ipecacuanha produces ipecac alkaloids, a series of monoterpenoid-isoquinoline alkaloids such as emetine and cephaeline, whose biosynthesis derives from condensation of dopamine and secologanin. Here, we identified three cDNAs, IpeOMT1-IpeOMT3, encoding ipecac alkaloid O-methyltransferases (OMTs) from P. ipecacuanha.

Cyclotide discovery in Gentianales revisited--identification and characterization of cyclic cystine-knot peptides and their phylogenetic distribution in Rubiaceae plants. [PDF]

open access: yesBiopolymers, 2013
ABSTRACT Cyclotides are a unique class of ribosomally synthesized cysteine‐rich miniproteins characterized by a head‐to‐tail cyclized backbone and three conserved disulfide‐bonds in a knotted arrangement. Originally they were discovered in the coffee‐family plant Oldenlandia affinis (Rubiaceae) and have since been identified in several species of the ...

Substrate‐binding glycine residues are major determinants for hydrolase and ligase activity of plant legumains

open access: yesNew Phytologist, Volume 238, Issue 4, Page 1534-1545, May 2023., 2023
Summary Peptide asparaginyl ligases (PALs) are useful tools for precision modifications of proteins and live‐cell surfaces by ligating peptides after Asn/Asp (Asx). They share high sequence and structural similarity to plant legumains that are generally known as asparaginyl endopeptidases (AEPs), thus making it challenging to identify PALs from AEPs ...

Coevolution as an engine of biodiversity and a cornucopia of ecosystem services

open access: yesPLANTS, PEOPLE, PLANET, Volume 3, Issue 1, Page 61-73, January 2021., 2021
Coevolutionary processes, which have governed interactions between organisms throughout the history of life, also serve as an engine of ecosystem services for humans. The escalating arms races between plants and herbivores, flowers and pollinators, have generated a cornucopia of foods, raw materials, perfumes, spices, ornamentals, medicines, and drugs.

Production, Transmission, Pathogenesis, and Control of Dengue Virus: A Literature‐Based Undivided Perspective

open access: yesBioMed Research International, Volume 2021, Issue 1, 2021., 2021
Dengue remains one of the most serious and widespread mosquito‐borne viral infections in human beings, with serious health problems or even death. About 50 to 100 million people are newly infected annually, with almost 2.5 billion people living at risk and resulting in 20,000 deaths.

Medicinal Plants Used as Antitumor Agents in Brazil: An Ethnobotanical Approach

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2011, Issue 1, 2011., 2011
In this study, we describe the medicinal plants that have been reported to be antitumor agents and that have been used in ethnobotanic research in Brazil to answer the following questions: what is the abundance of plants reported to be antitumor in Brazil?
