AI Technical Summary

Problems solved by technology

Therefore, acceptance in the public domain is low, and the cost of deregulation is very high
Furthermore, there are strict legal restrictions regarding the commercialization of such plants or their seeds
[0007] This is the reason why glyphosate, even though it is a well-studied and highly effective herbicide system, is not used commercially in sugar beet in many parts of the world

Embodiment

[0157] The seeds of the 6kg beet excellent product T807 (3BT1760, M0 population) were mutageneted by 0.5% EMS and 0.3% and 0.5% ENU, respectively, and then drilled to produce a seedlings (Steck). The seedlings are replanted to produce seeds, accounting for 5.8HA. The M1 population is a seed 19,000 plants of the EMS 75,000 seeds producing plants and ENU mutagenesis. The following M2 seed quantity (purified seed): 0.5% EMS 240kg (identifier A and B), 0.3% ENU 548kg (identifier C and D) and 0.5% ENU 256kg (identifier E and F).

[0158] A and B and 75kg identification C, D, E and F seeds are identified in the field sowing of approximately 15 hA span. After about 1 month, the entire field sprayed 0.88L / ha MAX (680 g / kg glyphosate). About 6 weeks later, plants survived in the field were collected in the field, and they were transplanted into the basin and further cultivated in the greenhouse. After about 2 months, surviving plants were treated with 600 g / ha glyphosphosphinate. 17...

Abstract

The present invention relates to the use of a glyphosate herbicide for controlling the unwanted vegetation in Beta vulgaris growing areas, wherein the Beta vulgaris plants comprise an endogenous allele encoding an epsp synthase having at position 179 an amino acid different from proline.

Description

[0001] Field of invention [0002] The present invention relates to the use of herbicides, in particular glyphosate, for controlling weeds in sugar beet growing areas, and to glyphosate tolerant sugar beet plants. [0003] Background of the invention [0004] Sugar beet (Beta vulgaris) is grown as a commercial crop in many countries, with total harvests exceeding 240 million tons. N-Phosphonomethylglycine, commonly known as glyphosate, is a broad-spectrum herbicide that is widely used due to its high efficacy, biodegradability, and low toxicity to animals and humans. Glyphosate inhibits the shikimate pathway, which causes the biosynthesis of aromatic compounds including amino acids and vitamins. Specifically, glyphosate inhibits the conversion of phosphoenolpyruvate and 3-phosphoshikimate into 5-enolpyruvyl-3-phosphate shikimate synthase (EPSP synthase or EPSPS) by inhibiting the enzyme 5-enolpyruvyl-3-phosphate shikimate synthase (EPSP synthase or EPSPS). Enolpyruvate-3-phos...
