  • Patent number: 8633354
    Abstract: To produce early flowering genotypes, plum (Prunus domestica) was transformed with the poplar (Populus trichocarpa) Flowering Locus T1 (PtFT1) gene. Ectopic expression of 35S::PtFT1 Induced early flowering in vitro from transgenic plantlets within two months of transformation. When the transgenic plum plants were rooted and transferred to soil and grown in posts in the growth chamber, a number of additional lines flowered. Normal flowering and fruiting were observed in the greenhouse within one year of transformation. While dormancy was not necessary for growth or fruiting, FT plums were still winter hardy and floral bud set and flowering responded normally to changes in temperature. By manipulating a single gene, temperate tree crops can be effectively engineered for cultivation in new growing areas and for entirely new modes of agricultural production that are continuous, sustainable, and adaptable to climate change.

  • Patent number: 7624428
    Abstract: An apparatus and method for platform and device independent identity manageability. In one embodiment, the method includes validation of a manageable identity (MID) held within trusted storage of a user platform according to a user request to move the MID to a target platform. Once the MID is validated, available resources of the target platform are verified according to resource requirements of the MID. Once verified, the MID may be moved from the user platform to trusted storage provided by the target platform. In one embodiment, a platform-independent MID may be established that may be moved from a user platform to a non-compatible target platform, such that the platform-independent MID is not constrained to just one single platform. Other embodiments are described and claimed.
