Selection of high pyrethrin producing tissue cultures.

Area of Science:

• Plant Biotechnology
• Natural Product Biosynthesis
• Agricultural Science

Background:

• Pyrethrum (Tanacetum cinerariifolium) is a source of natural insecticides.
• Axenic callus and shoot cultures demonstrate pyrethrin biosynthesis potential.

Purpose of the Study:

• To investigate the influence of explant source on pyrethrin biosynthetic capacity in pyrethrum tissue cultures.
• To identify high-yielding pyrethrum tissue lines for pyrethrin production.

Main Methods:

• Establishing axenic callus and shoot cultures from various explant organs of high and low-yielding pyrethrum selections.
• Describing culture establishment conditions.
• Analytical screening of tissue lines for pyrethrin content.

Main Results:

• Successful establishment of pyrethrum tissue cultures.
• Selection of several high-yielding pyrethrum strains derived from high-yielding parent plants.
• Differentiated cultures exhibited higher pyrethrin production compared to undifferentiated callus cultures.

Conclusions:

• Explant source significantly influences pyrethrin biosynthesis in pyrethrum tissue cultures.
• Differentiated cultures are more effective for pyrethrin production than callus cultures.
• This research identifies promising pyrethrum strains for biotechnological production of pyrethrins.
