Abstract: An LED light bulb is provided. The LED light bulb includes a lamp housing, a bulb base, a stem, first and second conductive supports, a driving circuit, and a flexible LED filament. The flexible filament includes two conductive electrodes, a first LED section, a second LED section, and a conductive section. The first LED section is bent in a first space curved shape. The second LED section is bent in a second space curved shape. The conductive section includes a center point of the flexible LED filament. The flexible LED filament is bent in a third space curved shape comprising the first space curved shape and the second space curved shape.

Abstract: An LED lamp includes: a lamp shell having a circular cross-section along a central axis of the lamp shell comprising a lamp neck and a sleeve; a heat sink comprising a plurality of fins, sleeving over the sleeve and connecting to the lamp neck; a power source comprising a power board and a plurality of electronic components mounted thereon disposed in the lamp neck and the sleeve; a light board comprising an opening at center portion and disposed at second end of the heat sink and physically and thermally connecting to the heat sink; a plurality of LED chips mounted on the light board and electrically connecting to the power source; and a lamp cover disposed at the second end of the heat sink and covering the plurality of LED chips; wherein the sleeve and the opening of the light board defines a first heat dissipating channel, the plurality of fins and the opening of the light board defines a second heat dissipating channel, the first heat dissipating channel and the second heat dissipating channel share the

Abstract: The anther recruits a number of specific-genes to support microspore development. Here we report identification of a novel gene, RAFTIN1, from bread wheat and rice, encoding a protein containing a BURP domain hallmarked with 4 CII repeats at its C-terminus. This single copy gene (per haploid complement in cereals) is exclusively expressed in the tapetum during postmeiotic stages when the young microspore undergoes rapid expansion. RAFTIN1 is biosynthesized in the tapetum, transported into the Ubisch body, and further deposited onto the microspore exinewall. Transgenic rice, in which RAFTIN1 expression is down-regulated, shows normal growth and development hut also shows male sterility. In the RAFTIN1-less anther, tapetal degeneration is retarded and pollen lacks contents. Thus, RAFTIN1 assembly in the Ubisch body and the microspore exinewall is required for microspore development, probably for regulation of metabolite transport from the tapetum to the microspore.

Abstract: The present invention provides isolated and purified polynucleotide sequences encoding fatty acyl Co-A reductase (FAR) enzymes derived from wheat, designated TAA1 genes. The invention encompasses genes that encode FAR enzymes that are useful in the production of transgenic plants and other organisms that comprise increased or otherwise altered levels of fatty alcohols. Such plants may have significant commercial value for the production of fatty alcohols for use in nutritional and pharmaceutical compositions. The invention also provides corresponding TAA1 anther-specific promoters, suitable for the expression of proteins other than FAR enzymes in the anthers and pollen cells of suitably transformed plants.
