Description of the two novel methods of synthesis of MO which produce the pure, biologically active auxin compound of MO. Discovery and description of the causes for the erroneous classification of MO as an inert compound with no auxin activity. These findings and methods of synthesis correct the ubiquitous theoretical errors which have driven scientific investigation and plant science research of plant auxins for nearly forty years. n Researchers have failed to observe the auxin activity of MO because of the use of standard but incorrect synthetic techniques which have consistently produced impure forms of 3 -bromooxindole- 3 -acetic acid ( 3 -Brox), the synthetic precursor of MO. In addition, the use of dimethylsulfooxide as a solvent for MO has been identified as a major source of contamination of MO during synthesis. n This invention describes two novel methods for synthesizing (MO). By using purified MO and avoiding the use of dimethylsulfoxide, it was found that the resulting MO product to be 100 to 1,00 fold more effective than IAA in promoting rooting in plant cuttings; supporting tissue differentiation and growth in stage I, stage II and stage III media used for the micropropagation of explants; promoting the formation of callus tissue over wounded plant parts; and, stimulating the production of interstitial tissue between scion and rootstock to increase the success rate for grafting. Therefore, this invention identifies MO as the dominant auxin in shoot acceleration, root development, wound sealing and scion acceptance. n Finally, the correct pathway from IAA to MO is presented.

Namely, a method of monitoring the synthesis of gibberellin and abscisic acid in germinating barley seeds during barley milling which comprises measuring the expression levels of gibberellin 3β-hydroxylase gene (HvGA3ox), gibberellin 20-oxidase gene (HvGA20ox) and 9-cis-epoxycarotenoid dioxygenase gene (HvNCED).
专利号:US-2025304985-A1 优先权日:2022-04-08 标题 :Genetically Engineered Plants for Increased Production of Vindoline 发明人:LEE-PARSONS CAROLYN; COLE LAUREN F 权利人:UNIV NORTHEASTERN 摘要:Two novel transcription factors, CrDELLA1 and CrDELLA2, are described in Catharanthus roseus plants. The DELLA transcription factors have a regulatory role in the synthesis of vinblastine and vincristine, two important anti-cancer compounds that have proved difficult to obtain in sufficient quantities. The present technology provides genetically modified C. roseus plants having enhanced DELLA activity, which leads to activation of multiple enzymes in the biosynthetic pathway leading to vinblastine and vincristine. The genetic modifications can be used together with activation of plant defense mechanisms and responses to light in order to boost vinblastine and vincristine synthesis.
