"If we can harness the ability of microbes to fix atmospheric nitrogen for crop production" she says, "that would potentially precipitate the second green revolution." (Read " The Next Green Revolution " in National Geographic magazine.)
...to the background information obtained for this patent, NewsRx journalists also obtained the inventors' summary information for this patent: "The present invention discloses the use of thaxtomin as a pre or post-emergence herbicide against most common weeds in the cereal, pasture grass, Timothy grasses and turf grass, residential gardens, vineyards, orchards and park growth systems. A 'growth system' may be any ecosystem for growing cereal, pasture grass, Timothy grass and turf grass. For example, a 'cereal growth system' may be a cereal growth culture or may be a field containing planted cereal crops or cereal seeds. Similarly, a 'turf grass growth system' may be a turf grass growth culture or may be a field, lawn or golf course containing planted turf grass or turf grass seeds. It can serve as a safer alternative to synthetic herbicides now on the market. A primary object of the invention is to provide novel herbicidal compositions against both broadleaf, sedge and grassy weeds, which include but are not limited to Chenopodium sp. (e g., Chenopodium album), Abutilon sp. (e g., Abutilon theophrasti), Helianthus sp. (e g., Helianthus annuus), Ambrosia sp. (e g., Ambrosia artemesifolia), Amaranthus sp. (e g., Amaranthus retroflexus),Convolvulu sp. (e g., Convolvulus arvensis), Brassica sp. (e g., Brassica kaber), Taraxacum sp. (e g., Taraxacum officinale), Solanum sp. (e g., Solanum nigrum), Malva sp. (e g., Malva neglect), Setaria sp. (e g., Setaria lutescens), Bromus sp. (e g., Bromus tectorum), Poa sp. (e g., Poa annua, Poa pratensis), Lollium sp. (e g., Lolium perenne L var. Pace), Festuca sp. (e g., Festuca arundinaceae) Schreb. Sp. (e g., Schreb. var. Aztec II, Anthem II, LS 1100), Echinochloa sp. (e g., Echinochloa crus-galli), and particularly, Lambsquarter--Chenopodium album, Redroot Pigweed--Amaranthus retroflexus, Wild Mustard--Brassica kaber, Dandelion--Taraxacum officinale, and Black Nightshade--Solanum nigrum, that contains thaxtomin as an active ingredient. Another object is to provide a safe, non-toxic herbicidal composition that does not harm cereal crops, pasture grass, Timothy grass or turf grass and a method that will not harm the environment."
According to the news editors, the research concluded: "Although the HPO A9 clone showed the lowest homology with HPO11172, clones in group B, including CS19, showed a relatively higher homology of 80%, with 70% identy. E coli cells expressing these HPO chimeric genes were able to successfully bioconvert chlorodimedone with KBr or KCl as substrate."
