The present invention provides a stevia plant having a low ability to form flower buds as compared with the wild type stevia species. The present invention also provides a method of producing such a stevia plant having a low ability to form flower buds, and an extract or a steviol glycoside purified product obtainable from such a plant.

The disclosure relates to a method for the generation of plants, such as Euphorbia pulcherrima, having a dysfunctional glutathione S-transferase (GST), and the seeds, plant parts or plant cells derived therefrom. The disclosure further relates to a molecular marker capable of identifying a dysfunctional GST gene, to isolated DNA encoding such a dysfunctional GST gene and to the use of such DNA for the preparation of a molecular marker and for use in methods of targeted mutagenesis to inactivate the GST gene to generate plants with a white foliage phenotype.

Disclosed herein are methods for manufacturing plant messenger packs (PMPs), which can be formulated for use in a variety of agricultural and therapeutic methods.

Disclosed is a use of the BXL gene or a protein encoded thereby. Specifically, when the expression of the BXL gene or a protein encoded thereby is inhibited, traits of plants can be significantly improved, comprising: (i) enhancing the stress resistance of plants; and/or (ii) the resistance to pathogens; and/or (iii) reducing lignin content and increasing fiber and pectin content. In addition, inhibitors of the BXL gene or a protein encoded thereby can also be used in feed compositions, and are used for improving feed palatability.

The present invention provides a method for increasing the artemisinin yield in Artemisia annua L. using β-ocimene and belongs to the technical field of artemisinin production and extraction. The method treats Artemisia annua L. plants by β-ocimene for 1-3 d. The method selects Artemisia annua L. grown for at least 21 d as the object to be treated by β-ocimene. The method is very simple and can achieve multiple harvest within one year; meanwhile, it can significantly increase the artemisinin yield in Artemisia annua L. plant and largely increase the artemisinin yield, thereby achieving an industrialized operation.

A method alters genetic material of a plant, which is capable of growing flower buds, when grown from soil and in an atmosphere. The method includes modifying the soil to have a pH below 7.0. The method also includes the step of eliminating free oxygen in the atmosphere when the flower buds of the plant become visible.
