  • Patent number: 11572570
    Abstract: Compositions and methods for increasing plant growth for higher crop yield are provided. The methods involve the expression in a plant of interest of at least one C4 transporter coding sequence. Plants showing increased expression of one or more C4 transporter coding sequence of interest are encompassed by the invention. It is recognized that any method for increasing the expression of the C4 transporter coding sequences in a plant of interest can be used in the practice of the methods disclosed herein. Such methods include transformation, breeding and the like. Increased expression of the C4 transporter coding sequences in the plant of interest results in yield gains. Expression cassettes and vectors comprising the C4 transporter sequences disclosed herein are also provided herein. Methods for identifying genes under positive selection in plants that use C4 photosynthesis are disclosed and provided herein.

  • Patent number: 11168331
    Abstract: Provided are plants that express, or overexpress, a pPLAIII? protein. Constitutive or seed-specific expression of pPLAIII? protein in Arabidopsis increases seed oil content, the amount of C20 and C22 fatty acids, and the amount of C56, C58, and C60 triacylglycerols, effectively resulting in significantly higher oil yield per plant. Use of pPLAIII? is therefore an effective biotechnological tool to significantly increase plant yield, including oil, and the amount of high value long chain fatty acids in agricultural and horticultural crops, especially oilseed crops.

  • Patent number: 11116154
    Abstract: A field controller and sensor is presented as an elongate body having a hollow interior and axially opposite first and second ends with a first arm extending outward from the elongate body adjacent to the first axial end and a second arm extending outward from the elongate body adjacent to the second, axially opposite end. Each of the arms has an imaging device. The first arm imaging device is positioned to obtain images in a direction toward the second axial end of the elongate body. The second arm imaging device is positioned to obtain images in a direction toward the first axial end. The first and second arms are spaced apart from one another along a length of the elongate body at a distance sufficient to image a canopy of crop growth in a field in which the field controller and sensor is deployed.

  • Patent number: 11053513
    Abstract: Provided are plants that express, or overexpress, type III G? protein AGG3. Such plants exhibit faster vegetative and reproductive growth, accompanied by an increase in photosynthetic efficiency. Constitutive or seed-specific expression of AGG3 in Camelina increases seed size, seed mass, and seed number per plant by 15-40%, effectively resulting in significantly higher oil yield per plant. AGG3-expressing Camelina plants also exhibit improved stress tolerance. Use of AGG3 is therefore an effective biotechnological tool to dramatically increase stress tolerance and plant yield, including oil, in agricultural and horticultural crops.
