    • Compositions related to the quantitative trait locus 6 (QTL6) in maize and methods for their use are provided. The compositions are novel molecular marker loci that are genetically linked with QTL6 and which are associated with increased oil content and/or increased oleic acid content and/or an increased oleic acid/linoleic acid ratio of a plant or plant part thereof. These novel markers are characterized by the presence of at least one polymorphism relative to the corresponding marker locus from the QTL6 region of non-high-oil, non-high-oleic acid maize plants. In some embodiments, the novel marker loci comprise coding sequence for a maize DGAT1-2 polypeptide or biologically active variant thereof. The marker loci of the invention, and suitable fragments thereof, are useful in methods of the invention for manipulating oil and/or oleic acid content and/or oleic acid/lineolic acid ratio of a plant or plant part thereof, for marker-assisted selection of a plant, for example, a maize plant, or plant part thereof, having an increased oil content and/or increased oleic acid content and/or an increased oleic acid/linoleic acid ratio, and for marker-assisted breeding of the high oil and/or high oleic acid trait.

    • A baud rate acquisition circuit (10) for synchronizing a sampling signal with an input signal operates in broad rate sweeping and a rate fine tuning phases. In the rate sweeping phase, a timing error detector (24) examines the sampling signal generated by a decimator (16). If the sampling signal is outside a rate acquisition range from the target rate, a rate sweeping algorithm selects a new sampling rate. In response to the sampling rate within the rate acquisition range, the timing error detector (24) examines the asymmetry thereof to generate a rate correction signal to synchronize the sampling signal with the input signal. Next in the rate fine tuning phase, a multiplexer (22) routes the sampling signal through a square root filter (18). By examining the waveform shaped signal, the time error detector (24) synchronizes the sampling signal with the input signal with high accuracy.
    • 用于使采样信号与输入信号同步的波特率采集电路(10)以广泛的频率扫描和速率微调相位工作。 在速率扫描阶段中,定时误差检测器(24)检查由抽取器(16)产生的采样信号。 如果采样信号在目标速率以外的速率采集范围之外,则速率扫描算法选择新的采样率。 响应于速率采集范围内的采样率,定时误差检测器(24)检查其不对称性,以产生速率校正信号,以使采样信号与输入信号同步。 接下来在速率微调相位中,多路复用器(22)将采样信号通过平方根滤波器(18)。 通过检查波形信号,时间误差检测器(24)以高精度同步采样信号与输入信号。
