TLDR
Co-heritability between caffeine and theobromine was positive, suggesting that additive genetic correlations and dominance correlations are concurring, and the strong influence of paternal progenitors regarding caffeine needs more research.Abstract:
In order to start a genetic improvement program for quality in the Mate crop (Ilex paraguariensis), it was attempted to estimate the actual genetic parameters of caffeine, theobromine and related quality traits, using available progeny tests in Misiones, Argentina Using cluster analysis, eight groups of similar characteristics could be identified, and individual within full-sib family selection for quality was performed Additive effects were strong for caffeine but weak for theobromine Co-heritability between caffeine and theobromine was positive, suggesting that additive genetic correlations and dominance correlations are concurring The strong influence of paternal progenitors regarding caffeine needs more researchread more

TL;DR: The Scientific Panel on Contaminants in the Food Chain (CONTAM Panel) concluded that because PTX-group toxins do not share the same mechanism of action as OAgroup toxins they should not be included in the regulatory limit for OA- group toxins.

Effect of growing and drying conditions on the phenolic composition of mate teas (Ilex paraguariensis).
TL;DR: On average, plantation grown Mate teas had a greater concentration of phenolics than forest grown teas, and represent better potential sources for their commercial extraction.

Mapping and validation of PCR-based markers associated with a major QTL for seed dormancy in wheat
TL;DR: A major quantitative trait locus (QTL) for seed dormancy on the long arm of wheat chromosome 4A (4AL) is identified via simple sequence repeat (SSR)-based genetic mapping using doubled haploid lines from a cross between Japanese PHS resistant variety ‘Kitamoe’ and the Alpine non-resistant variety “Münstertaler” (K/M).

TL;DR: In this paper, the methylxanthines and phenolic compounds contents of 16 mate (Ilex paraguariensis St. Hil.) progenies from four Brazilian regions (Ivai, Quedas do Iguacu, Cascavel and Barao de Cotegipe) were evaluated.

Chlorogenic acids and purine alkaloids contents of Mate (Ilex paraguariensis) leaf and beverage
TL;DR: In this article, five samples of Mate leaf have been analysed for chlorogenic acids, caffeine and theobromine, and found to comprise two distinct categories of product: brown extracts and infusions with relatively small contents of alkaloids and total chlorogenic acid, whereas Category 2 produced green extracts and Infusions with larger total alkaloid contents and much larger total acid contents.

TL;DR: In this article, Ilex dumosa leaves, a material frequently used for the adulteration of erva-mate, were extracted for the extraction of 3-O-β-d-glucuronopyranosyl (3β-hydroxyolean-12-en-28-oic acid).

TL;DR: The mathematical relations between co-heritability, correlated response, and the coefficient of genetic prediction are shown and exploratory indicators are proposed to estimate the nature of the genetic association.
