    Abstract: The invention discloses maize bZIP transcriptional factors, namely, ABP2, ABP4 and ABP9, the genes encoding these factors, and the use thereof. The transcriptional factors are proteins having an amino acid sequence set forth in SEQ ID NO: 2, 4, or 6, or proteins derived therefrom by substitution, deletion or addition of one or more amino acid residues of SEQ ID NO: 2, 4, or 6, and having the same activity as a protein shown by SEQ ID NO: 2, 4, or 6. The ABP2, ABP4 and ABP9 genes encoding these factors, respectively, are the DNA sequences having an identity of more than 90% with a sequence shown by SEQ ID NO: 1, 3 or 5 and the encoded proteins having such same functions. These genes are important for breeding plant varieties with an enhanced tolerance to abiotic stresses and for improving plant tolerance to abiotic stresses.

    Abstract: A method of carrying SDH services in PON is provided, in which tributary units carrying SDH service data are mapped into payload part of GEM frames, thereby implementing transmission of SDH services in GPON. De-capsulation is performed in reverse process at receiving end. A device of receiving or transmitting SDH services and a method of mapping SDH data frame into PON data frame are also provided. The present invention may be merged with SDH network directly since standard SDH tributary unit structure is adopted, and extraction of virtual containers that includes SDH service data and synchronism can be accomplished conveniently based on pointer adjustment mechanism adopted by tributary units.

    Abstract: Embodiments of the present invention disclose a method for detecting an upstream timeslot conflict in a Passive Optical Network (PON). An Optical Line Terminal (OLT) detects a timeslot conflict in an upstream timeslot. An OLT is provided also, including an optical receiver, an optical transmitter, a control unit and a detection unit. The detection unit receives an optical signal from the optical receiver, samples instantaneous optical power of the optical signal in an upstream timeslot, compares the instantaneous optical power with normal upstream optical power of the upstream timeslot, and detects that a timeslot conflict occurs in the upstream timeslot when the instantaneous optical power exceeds normal upstream optical power of the upstream timeslot. Embodiments of the present invention make the costs lower to detect an upstream timeslot conflict in the PON.

    Abstract: In a method of accessing a single port memory, a plurality of read commands are received from a plurality of requestors for memory read access. A respective plurality of parameters corresponding to each of the plurality of read commands is stored in a memory read command queue. The parameters corresponding to one of the read commands are retrieved from the memory read command queue when the single port memory provides the data corresponding to that read command. One or more of the parameters from the memory read command queue are provided while providing the data from the memory.
