Cover image - The image shows the animals of Bos indicus in the feedlot system. This breed represents about 80% of Brazilian herd. The calibration of Davis growth model was performed for the largest national database of Bos indicus, based on the Nutrition and Animal Growth Laboratory (LNAG) at ESALQ - University of São Paulo, Brazil.

Cover image - The image shows a cross-section of a leaf inoculated with the Xanthomonas citri subsp. citri, bacterium responsible for citrus canker disease. The bacteria invade host mesophyll throughout natural openings such as stomata, and lesions. By seven days after inoculation, a typical hyperplasia and hypertrophy of mesophyll cells were observed, followed by rupture of abaxial epidermis and exposing the bacteria oozing at the site of infection.

Cover image - The image refers to oat plants grown in Southern Brazil. The study investigated heterosis in oat crosses for grain quality traits. Oat grains are known for their benefits to human health, regarding their soluble fiber content and other components. The combination Albasul × UPF 15 provided significant heterosis for the traits β-glucan total and soluble fiber contents, while the population obtained by crossing IAC 7 × UFRGS 19 generated significant gain by heterosis for total fiber, insoluble fibers and non-structural carbohydrate contents.

Cover image - The image shows Chilean Black Friesian (Holstein × Black Friesian) cows, the most important dairy breed in Chile, producing about 80% of the milk received by dairy industry. Cattle production systems are mostly based on grazing (southern Chile), which according to our study promotes higher conjugated linoleic acid (one of the most potentially beneficial fatty acids for human health) concentrations in their milk when compared to non or low grazing animals.

Cover image - The picture shows the plasma membrane H+-ATPase proton transport in vivo and the consequent vanadate-sensitive root acidification of wild type Micro-Tom. This rhizosphere acidification is an easy bioassay to check for biostimulants activity. The developed yellow colour indicates acidic pH, purple colour denotes neutral to alkaline pH.
