Desert Microbes can help sustainable agriculture in extreme environments

The study: Desert Microbes for Boosting Sustainable Agriculture in Extreme Environments, published on the Frontiers in microbiology, showed how desert microbes can be used to help sustainable agriculture, which is a crucial hub for the subsistence of the future of our sons.

We can read: "A large portion of the earth's surface consists of arid, semi-arid and hyper-arid lands. Life in these regions is profoundly challenged by harsh environmental conditions of water limitation, high levels of solar radiation and temperature fluctuations, along with soil salinity and nutrient deficiency, which have serious consequences on plant growth and survival.

In recent years, plants that grow in such extreme environments and their naturally associated beneficial microbes have attracted increased interest. The rhizosphere, rhizosheath, endosphere, and phyllosphere of desert plants display a perfect niche for isolating novel microbes.

They are well adapted to extreme environments and offer an unexploited reservoir for bio-fertilizers and bio-control agents against a wide range of abiotic and biotic stresses that endanger diverse agricultural ecosystems.

Their properties can be used to improve soil fertility, increase plant tolerance to various environmental stresses and c rop productivity as well as benefit human health and provide enough food for a growing human population in an environment-friendly manner.

Several initiatives were launched to discover the possibility of using beneficial microbes. In this review, we will be describing the efforts to explore the bacterial diversity associated with desert plants in the arid, semi-arid, and hyper-arid regions, highlighting the latest discoveries and applications of plant growth promoting bacteria from the most studied deserts around the world."

Why should we eat pomegranates?

The pomegranate is a berry with a very robust consistency, with a very hard and leathery skin, it has a round or slightly elongated shape, sometimes sub-hexagonal, with a diameter from 5 to 12 cm and with a size strongly conditioned by the variety and, above all, by the conditions of cultivation.

The fruit has several robust internal partitions that perform the function of placentation for the seeds, called grains or arils separated by a membrane called cica. The seeds, red in color, in some varieties are surrounded by a translucent pulp colored from white to ruby ​​red, more or less acidulous and, in the edible fruit varieties, sweet and fragrant.

In the apical position the fruit bears a characteristic robust crown of four to five pieces, which are residues of the floral calyx. The fruit ripens in October-November, depending on the variety. The study: Composition and Potential Health Benefits of Pomegranate: A Review, published on the Current pharmaceutical design, said us: "Pomegranate (Punica granatum L.) fruits are widely consumed and used as preventive and therapeutic agents since ancient times.

Pomegranate is a rich source of a variety of phytochemicals, which are responsible for its strong antioxidative and anti-inflammatory potential. The aim of this review is to provide an up-to-date overview of the current knowledge of chemical structure and potential health benefits of pomegranate.

A comprehensive search of available literature. The review of the literature confirms that juice and extracts obtained from different parts of this plant, including fruit peel, seeds, and leaves exert health benefits in both in vitro and in vivo studies.

The antidiabetic, antihypertensive, antimicrobial and anti-tumor effects of pomegranate fruit are of particular scientific and clinical interest. Further investigations are required to clarify the mechanism of action of the bioactive ingredients and to reveal full potential of pomegranate as both preventive and therapeutic agent."
