CRISPR Boosts Immunity and Yield of Wheat

Researchers used CRISPR-Cas9 in wheat, which improved its resistance to rust and increased its yield. Their findings offer germplasm resources that can be used for the breeding of high-resistance and high-yield plants.

The immune system of plants is regulated positively and negatively by different factors. An example of a negative regulator of plant immunity is MAP kinase phosphatase1 (MKP1). However, the molecular mechanisms involving MKP1's regulation of wheat (Triticum aestivum) are currently unclear.

Residue Management

Video: Residue Management

Residue Management conservation practice manages the amount, orientation, and distribution of crop and other plant residue on the soil surface year-round while limiting soil-disturbing activities used to grow and harvest crops in systems where the field surface is tilled prior to planting. This video explores how Ryan McKenzie implemented this conservation practice on his farm in Samson, Alabama.

Practice benefits:

• Increases organic matter

• Improves air quality

• Decreases energy costs

• Reduces erosion

• Improves soil health

The Conservation at Work video series was created to increase producer awareness of common conservation practices and was filmed at various locations throughout the country. Because conservation plans are specific to the unique resource needs on each farm and also soil type, weather conditions, etc., these videos were designed to serve as a general guide to the benefits of soil and water conservation and landowners should contact their local USDA office for individual consultation.
