摘要:
The invention provides transgenic plants with resistance to infection by a root-infecting fungal plant pathogen such as Phymatotrichopsis omnivora. Also provided are methods of making such plants. Further provided are nucleic acid vectors for producing such a plant. Additionally, methods are provided for growing a dicotyledonous plant that is resistant to root rot disease in soil that comprises Phymatotrichopsis omnivora, or another pathogen.

A catalyst used in the reaction of oxidative bromination of methane is provided. The catalyst is prepared by the following procedures: mixing at least one of the precursors selected from the compounds of Rh, Ru, Cu, Zn, Ag, Ce, V, W, Cd, Mo, Mn, Cr and La which can dissolve in water with the Si precursor, hydrolyzing, drying and sintering. In the catalysis system, methane reacts with HBr, H2O and oxygen source (O2, air or oxygen-rich air), finally CH3Br and CH2Br2 are produced. Another catalyst used in the reaction of condensation of methane bromide to C3-C13 hydrocarbons is also provided. This catalyst is prepared by supporting compounds of Zn or Mg on molecular sieves such as HZSM-5, HY, Hb, 3A, 4A, 5A or 13X et al. With this catalyst, CH3Br and CH2Br2 produced in the former process can react further to give C3 to C13 hydrocarbons and HBr, and HBr can be recycled as a medium.

A method for allocating a group bit rate among each line in a group of bonded lines in a communications network, the method comprising: receiving first and second actual bit rates (ACT1, ACT2) for first and second lines (L1, L2) of the group (G), respectively; calculating a splitting ratio (X) of the second actual bit rate to the first actual bit rate (X=ACT2/ACT1); if the splitting ratio (X) is within a predetermined range, determining ones of first and second minimum bit rates (MIN1, MIN2) and first and second maximum bit rates (MAX1, MAX2) for the first and second lines (L1, L2), respectively, from ones of the splitting ratio (X), a group minimum bit rate (MING), a group maximum bit rate (MAXG), and first and second preconfigured minimum bit rates (MINL1, MINL2) for the first and second lines (L1, L2), respectively; and, configuring first and second transceivers for the first and second lines (L1, L2), respectively, with ones of the first and second minimum (MIN1, MIN2) and maximum (MAX1, MAX2) bit rates.
摘要:
A process for converting methane into C3˜C13 hydrocarbons is provided including the steps of reacting methane with oxygen and HBr/H2O over a first catalyst in a first reactor to methane bromides and converting the methane bromides into C3˜C13 hydrocarbons and HBr over a second catalyst in a second reactor. The process may further include recovering HBr produced in the second reactor and recylcing it into the first reactor.

摘要:
The invention provides methods and compositions for making a dicotyledonous plant that is susceptible to Phymatotrichopsis Root Rot (PRR) more resistant to PRR, by metabolic engineering of the plant's flavonoid and isoflavonoid biosynthetic pathways. Thus, methods for increasing the synthesis and accumulation of medicarpin and/or 7,4′-dihydroxyflavone in plants such as alfalfa are provided.
摘要:
The present invention discloses a system and method to allow a browser frame, tab, or window to communicate with an arbitrary number of application hosts in different domains while keeping its location constant on a client host. The invention allows all communications to occur between the web browser and any of the applications hosts and the client host while the hosts do not to have any knowledge of each other and cannot exchange data between them. The present invention thereby allows the frame, tag, or window to persist arbitrary data and programs. The system specifically allows sending arbitrary HTTP messages to the application hosts and allows receiving the associated responses, while allowing every interaction with the client host that the user browser supports (e.g. HTTP, Ajax), and allowing continuous execution of a program in the user browser frame, tab, or window.
