Centromeric regions of plants are generally composed of large array of satellites from a specific lineage of Gypsy LTR-retrotransposons, called Centromeric Retrotransposons. Repeated sequences interact with a specific H3 histone, playing a crucial function on kinetochore formation. To study the structure and composition of centromeric regions in the genus Coffea, we annotated and classified Cen...

Polyploidization contributes to the complexity of gene expression, resulting in numerous related but different transcripts. This study explored the transcriptome diversity and complexity of the tetraploid Arabica coffee (Coffea arabica) bean. Long-read sequencing (LRS) by Pacbio Isoform sequencing (Iso-seq) was used to obtain full-length transcripts without the difficulty and uncertainty of ass...

Glyphosate is the main herbicide used in coffee (Coffea arabica L.) plantations in Brazil. Problems with herbicide drift commonly occur in orchard fields due to non-adequate spraying conditions. A series of experiments was carried out aiming to evaluate physiological dose-response of C. arabica plants submitted to exposure to simulated glyphosate drift in two distinct plant growth stages. Glyph...

BACKGROUND Helicobacter pylori (H. pylori) is linked to the development of the majority of peptic ulcers and some types of gastric cancers, and its antibiotic resistance is currently found worldwide. OBJECTIVE This study is aimed at evaluating the anti-H. pylori activity of Korean acacia honey and isolating the related active components using organic solvents. MATERIAL AND METHODS The crude...

Antiseptics are being used to prevent the growth of pathogens which are major causes of diseases. Unfortunately, not everyone can use these antiseptics because of its price in the market. With this, the use of plants as sources of antiseptics gives rise to the continuous study of indigenous plants. Extraction and isolation of constituents such as alkaloid are commonly studied. It is believed th...

The jewel beetle species Chrysobothrisdesmaresti (Laporte & Gory, 1836) and Hiperanthastempelmanni Berg, 1889, have been recorded in Bolivia for the first time. Both species were collected on xeric Acacia trees. As indicated by their presence on Acacia and previous records, both species may be endemic to the arid intermountain valleys of the Southern Bolivian and Northern Argentinean Andes as w...

Coffee is one of the most important plantation crops, grown in about 80 countries across the world. The genus Coffea comprises approximately 100 species of which only two species, that is, Coffea arabica (commonly known as arabica coffee) and Coffea canephora (known as robusta coffee), are commercially cultivated. Genetic improvement of coffee through traditional breeding is slow due to the per...

In the course of our continuing efforts to identify bioactive secondary metabolites from Red Sea marine invertebrates, we have investigated the sponge Hemimycale arabica. The antimicrobial fraction of an organic extract of the sponge afforded two new hydantoin alkaloids, hemimycalins A and B (2 and 3), together with the previously reported compound (Z)-5-(4-hydroxybenzylidene)imidazolidine-2,4-...

phenotypic and genotypic diversity as well as symbiotic effectiveness of twenty one symbionts isolated from nodules of four acacia species (acacia melanoxylon, a. mearnsii, a. saligna and acacia tortillis) grown in morocco were evaluated. growth in various media (yma, yma-bbt, yma-rc), colony morphology, tolerance to stress factors (temperature, ph, salt concentrations, various heavy metals) an...
