Abstract
Methods and compositions are disclosed to improve biomass accumulation in Truncated Light-harvesting Antenna (TLA) crop plant canopies as compared to biomass accumulation measured in wild-type counterparts grown under the same high canopy-density, agronomic, and ambient sunlight conditions.
Claims12
A method of obtaining plants having increased biomass accumulation, the method comprising cultivating a plurality of Truncated Light-harvesting Antenna (TLA) plants comprising individual TLA plants, wherein each of the TLA plants comprised by the plurality has a photosystem chlorophyll antenna size that is about 75% or less than the photosystem chlorophyll antenna size of a wild-type counterpart plant, wherein the TLA plants are planted:
- at a density such that plant density of the TLA plants in a monoculture is increased by at least 20%, at least 50%, at least 100%, at least 200%, or at least 300% over the density employed for the counterpart wild type plants.
A method of enhancing biomass productivity on a per cultivated surface area, the method comprising cultivating a TLA variant of a crop or wild type plant under conditions in which the planting density of the TLA plants is greater by at least 25%, at least 50%, at least 100%, at least 200%, or at least 300% over that employed for the corresponding wild type plant.
