Biosynthesis of epothilone intermediates with alternate starter units: Engineering polyketide-nonribosomal interfaces

, p. 3917 - 3921 (2003)
The early steps of epothilone biosynthesis were reprogrammed in vitro by incorporating enzyme subunits (e.g. EntB, EntE) from other biosynthetic pathways into the epothilone (Epo) assembly line (see scheme). Recognition sequences identified at the C termini of the epothilone biosynthetic proteins enabled heterologous enzyme transfer when fused to noncognate proteins, as a step toward the reengineering of biosythetic pathways to produce natural product analogues in vivo.
Novel weeding preparation and preparation method thereof

Paragraph 0047-0048, (2021/06/22)
The invention relates to the technical field of herbicides, in particular to a novel weeding preparation and a preparation method thereof. The novel weeding preparation includes at least one compound of formula (1) or formula (2). The novel weeding preparation is prepared by combining two compounds with novel structures, and parasitic weeds can be prevented and removed by adopting a 'suicide' germination strategy by utilizing the characteristic that parasitic weed seeds can germinate only by being stimulated and induced by allelochemicals, that is, before crops are planted, proper allelochemicals are sprayed on the land to induce the weed seeds to germinate, then the weeds finally die due to the fact that no corresponding hosts provide water and nutrition, and the purpose of effectively killing parasitic weed seed banks can be achieved. By using the weeding preparation provided by the invention, the soil inventory of weed seeds can be reduced, prevention and removal can be carried out before seedling emergence, the problems of crop quality reduction, pesticide residues, environmental pollution and the like are avoided, and the weeding preparation is a sustainable ecological parasitic weed comprehensive prevention and control strategy.
Compound capable of bidirectionally regulating plant growth and preparation method thereof
-
Paragraph 0057-0064, (2021/06/22)
The invention discloses a compound capable of bidirectionally regulating plant growth and a preparation method thereof, and particularly relates to the technical field of plant growth, and the structural general formula of the compound is as shown in formula (1). The compound provided by the invention is novel in structure, is not recorded in the prior art, can be used for preparing growth regulators for regulating the growth of main roots and lateral roots of plants under different concentration conditions, and can inhibit the growth of the main roots and promote the growth of fibrous roots in micromole. In nanomole, growth of fibrous roots is only promoted, and main roots are not affected. Targeted regulation and control can be carried out according to the growth requirements of different plants.
