Storage protein variability in natural populations of maté (Ilex paraguariensis) in Brazil

Abstract

Samples of 168 maté trees (Ilex paraguariensis) from four natural populations of different states of Brazil (Rio Grande do Sul, Santa Catarina, Paraná and Mato Grosso do Sul) were analyzed for their variability in storage proteins seed, which were used to estimate the degree of differentiation among and within species, because are relatively stable during evolution. Data on band presence/absence from 80 different polypeptides were used to perform similarity coefficient of Jaccard. A high level of genetic variability was reported within sampled populations (SJ intra=0.374). Lower levels of diversity were observed between populations (SJ inter=0.308). Total genetic diversity of maté was Hsp=0.264 estimated by Shannon measure. Partition of that value disclosed that 95 % of the total diversity is within-population, and only 5% to between-populations. The phenogram based on King’s distances indicates a certain degree of geographic differentiation. This represents the first study on storage protein variability in I. paraguariensis and guides the choice of the specimens to increment germoplasm banks and genetic improvement programs.

Hibiscus, Rooibos, and Yerba Mate for Healthy Aging: A Review on the Attenuation of In Vitro and In Vivo Markers Related to Oxidative Stress, Glycoxidation, and Neurodegeneration

“…Hibiscus (Hibiscus sp. ), rooibos (Aspalathus linearis), and yerba mate (Ilex paraguariensis) are important examples of herbal plants ( Figure 3 ) that are mostly found in African and South American local markets and have been traditionally used in the production of flavorful non-alcoholic beverages [ 88 , 89 , 90 ]. These plants have been demonstrated to have important health effects, such as as anti-cancer (in vitro) [ 91 ], anti-diabetes (in vivo) [ 92 ], or anti-inflammatory (in vivo) [ 93 ] effects.…”

Growth and Physiological Responses of Yerba Mate Seedlings and Mini-Cuttings Under Drought Stress

“…Hil.) is a tree species whose natural distribution occurs in the interior Atlantic Forest ecosystem (Argentina, Paraguay and Brazil) (Gregianini and Winge, 2019), and where most of the plantations are concentrated. In Argentina, the agroecological conditions for cultivation of this species include the provinces of Misiones and the northeast of Corrientes where a large production area of 160,000 ha exists to date (INYM, 2020).…”

Genetic relationship study of some Vicia species by FISH and total seed storage protein patterns

“…Seed storage proteins have been studied in several plant species for providing appropriate biological system for the evolution studies. Their patterns could be used to elucidate the degree of diversity between the different species or to discriminate the individuals within the same species [34][35][36][37][38], due to their stability during the course of evolution and are slightly affected by environmental conditions and seasonal changes [39,40].…”
