Abstract: A light source including a plate and an emitter array mounted on the plate extending from a first edge to a second edge. The plate can include a first edge; a second edge, the first edge being opposite the second edge; a first mount on the first edge; and a second mount on the second edge. Such light sources can be combined together.

Abstract: A semiconductor lighting device has an array of semiconductor light sources arranged in an x-y grid, a power input in electrical connection with the array and arranged to provide power to the light sources, a microcontroller in electrical connection with the array arranged to alter operation of the array as necessary, and a connector in electrical connection with the microcontroller, arranged to provide an interface to the microcontroller. The semiconductor lighting device has a first interface to allow a first level of access to the microcontroller by an end user, a second interface to allow a second level of access to the microcontroller for maintenance operations, and a third interface to allow a third level of access to the microcontroller during production.

Abstract: The present invention provides methods for regrowth of conifer embryogenic cells. The methods comprise the steps of (a) contacting cryopreserved conifer embryogenic cells with a liquid transition medium, and (b) culturing the contacted conifer embryogenic cells in a regrowth medium to generate regrowth of the conifer embryogenic cells. Generally, the cryopreserved conifer embryogenic cells are contacted with the liquid transition medium for less than about 24 hours, such as for about one hour.

Abstract: In one aspect, the present invention provides methods for producing conifer somatic embryos. The methods of this aspect of the invention each include the steps of cultivating conifer embryogenic cells in, or on, a synchronization medium that comprises an absorbent composition and at least one synchronization agent selected from the group consisting of abscisic acid and a gibberellin. Some embodiments of the methods provide a synchronized population of conifer somatic embryos wherein at least about 50% of the embryos are at about the same developmental stage. Some embodiments of the methods of the invention yield at least 100% more cotyledonary somatic embryos than an identical method for producing conifer somatic embryos that does not utilize a synchronization medium comprising an absorbent composition and at least one synchronization agent selected from the group consisting of abscisic acid and a gibberellin.
