How to Extract DNA from Anything Living. First, you need to find something that contains DNA.
Since DNA is the blueprint for life, everything living contains DNA. For this experiment, we like to use green split peas. But there are lots of other DNA sources too, such as: Spinach Chicken liver Strawberries Broccoli Certain sources of DNA should not be used, such as: Your family pet, Fido the dog Your little sister's big toe Bugs you caught in the yard Step 1: Blender Insanity! Put in a blender: 1/2 cup of split peas (100ml) 1/8 teaspoon table salt (less than 1ml) 1 cup cold water (200ml) Blend on high for 15 seconds. The blender separates the pea cells from each other, so you now have a really thin pea-cell soup. Step 2: Soapy Peas Pour your thin pea-cell soup through a strainer into another container (like a measuring cup). Add 2 tablespoons liquid detergent (about 30ml) and swirl to mix. Let the mixture sit for 5-10 minutes. Pour the mixture into test tubes or other small glass containers, each about 1/3 full. Aeroponics.

10 Homemade Organic Pesticides - My Gardening Stories. Ever wonder what farmers did hundreds of years ago to fight off crop pests?
Long before the invention of harmful chemical pesticides (yes, the kind that is linked to cancerous cellular activity), farmers and householders came up with multiple remedies for removing insect infestations from their garden plants. The following list will offer some of our favorite, all-natural, inexpensive, organic methods for making bug-busting pesticides for your home garden. 1.
Neem Ancient Indians highly revered neem oil as a powerful, all-natural plant for warding off pests. The Monsanto Equalizer: Patented BioTechnology Renders All Chemical Pesticides Obsolete. Most biotech companies, especially Monsanto have engaged themselves in the wanton tampering of Nature’s way of doing things for decades, the destructive effects of which are just beginning to be appreciated by the mainstream population.
Their motivation has always been about making bigger profits than the last one. Patent US7122176 - Mycoattractants and mycopesticides - Google Patents. This application is a continuation-in-part of application Ser.

Uzbek microbiologist Dilfuza Egamberdieva hopes to apply her new agricultural technique soon in Uzbekistan to boost the yield of economically important crops such as wheat, cotton, tomato and cucumber.
She presented her work at this year's TWAS General Meeting. Egamberdieva, group leader at the National University of Uzbekistan, at Tashkent, has isolated salt-tolerant bacterial strains that live in salt-degraded soils, where they help the rooting process in plants. After the selection of potentially root-colonizing bacteria, she has tested them in experimental settings on plants' roots, obtaining 10-15% yields increase. More than 2.6 billion people in the world rely on agriculture, but around 52% of the land used for this scope shows soil degradation.
Land impoverishment is often due to salt infiltrations in the ground, which weaken the plants and lower the yield. Breakthrough: How salt stops plant growth. Until now it has not been clear how salt, a scourge to agriculture, halts the growth of the plant-root system.
A team of researchers, led by the Carnegie Institution's José Dinneny and Lina Duan, found that not all types of roots are equally inhibited. They discovered that an inner layer of tissue in the branching roots that anchor the plant is sensitive to salt and activates a stress hormone, which stops root growth. The study, published in the current issue of The Plant Cell, is a boon for understanding the stress response and for developing salt-resistant crops.
Salt accumulates in irrigated soils due to the evaporation of water, which leaves salt behind. The United Nations estimates that salinity affects crops on about 200 million acres (80 million hectares) of arable land and not just in developing countries, but areas such as California as well. Hormones that guide root growth rates revealed. A plant's roots grow and spread into the soil, taking up necessary water and minerals.
The tip of a plant's root is a place of active cell division followed by cell elongation, with different zones dedicated to different functions, all working together to expand into new depths of the soil. Achieving an optimal root growth rate is critical for plant survival under drought conditions, as well as for maximizing resource allocation to the important plant parts such as the fruits and seeds. Want bigger plants? Get to the root of the matter. Plant scientists have imaged and analyzed, for the first time, how a potted plant's roots are arranged in the soil as the plant develops.
In this study, to be presented at the Society for Experimental Biology meeting on 30th June, the team has also found that doubling plant pot size makes plants grow over 40% larger. From their 3-D MRI root scans, the researchers observed that potted plants quickly extend their roots to the pot's walls. Plant welfare is improved by fungi in soil. A University of York biologist is part of an international team of scientists that has discovered how plants use fungi to help them to gather vital nutrients from the soil.
The team of Dr Michael Schultze, of the Department of Biology at York, working with colleagues in China, France and USA as well as the John Innes Centre at Norwich, studied the symbiosis between fungus and the roots of Medicago truncatula. The research may point the way to the development of higher yield crops using plants' own organic tools rather than fertilizers. The researchers found that a protein, known as a proton pump, at the interface of fungus and root cells energises cell membranes creating a pathway into the plant cell for nutrients such as phosphorus. Most plant species are able to exploit an intimate relationship with beneficial fungi in the soil to form mycorrhizas (fungal roots). Water found to provide blueprints for root architecture. Soil is a microscopic maze of nooks and crannies that hosts a wide array of life.
Plants explore this environment by developing a complex branched network of roots that tap into scarce resources such as water and nutrients. How roots sense which regions of soil contain water and what effect this moisture has on the architecture of the root system has been unclear. New research from a team led by Carnegie's José Dinneny focuses on how physical properties of a root's local environment control root branching and through which developmental pathways these signals act. Their findings, published by Proceedings of the National Academy of Sciences, describe a novel process called hydropatterning that allows plants to optimize root branching for water uptake.
Plant roots form a branching network like that above ground, with lateral roots growing out from a main axis. Desert farming forms bacterial communities that promote drought resistance. When there is little water available for plants to grow, their roots form alliances with soil microbes that can promote plant growth even under water-limiting conditions, according to research published Oct. 31 by Daniele Daffonchio and colleagues from the University of Milan, Italy in the open access journal PLOS ONE.
Symbiotic relationships between plants and soil microbial communities are critical to the health of plants. Though the effects of drought on plants are well-known, little is known about how lack of water affects the bacteria around plant roots. In this study, the researchers grew pepper plants under conditions of limited water and analyzed the bacterial species around the roots of the plants. They found that drought stress enriched the microbial communities with bacteria capable of increasing plant photosynthesis and biomass production by up to 40% under limited water conditions. Root microbiome engineering improves plant growth.
Humans have been breeding crops until they're bigger and more nutritious since the early days of agriculture, but genetic manipulation isn't the only way to give plants a boost. In a review paper published on September 25 in Trends in Microbiology, two integrative biologists present how it is possible to engineer the plant soil microbiome to improve plant growth, even if the plants are genetically identical and cannot evolve. These artificially selected microbiomes, which can also be selected in animals, can then be passed on from parents to offspring. Only a few published studies have looked at the effects of artificially selecting microbiomes. Aquaponics. 14 Genius Ways To Recycle Used Coffee Grounds.
