A process for in vitro induction of flowering/in vitro proliferation of floral primordia in saffron crocus (Crocus sativus L.) produces whole flowers with real stigmas. The process produces saffron through a process of in vitro flowering to obtain season independent, continuous flowering of saffron.

The present invention relates to a method of producing sesquiterpene lactones of the thapsigargin family, the method comprising the steps of: (a) culturing plant cells of the genus Thapsia in a nutrient medium in a suspension cell culture, wherein the cells produce one or more sesquiterpene lactones of the thapsigargin family; and (b) recovering one or more sesquiterpene lactones of the thapsigargin family produced in (a). The present invention further relates to a suspension cell culture comprising plant cells of the genus Thapsia, wherein the plant cells are capable of producing one or more sesquiterpene lactones of the thapsigargin family and to a plant cell biomass comprising plant cells of the genus Thapsia obtained from said suspension cell culture.

Cosmos bipinnatus cotyledons are isolated as explants, and the isolated explants are cultured onto a regeneration medium to obtain regenerated Cosmos bipinnatus shoots. The regeneration medium optionally includes a basal medium, a cytokinin, an ethylene action inhibitor, and a nitrogen source.

Methods of producing sugar cane transplant units that includes planting a sugar cane propagation material in a planting container that has a volume of 10 to 200 cubic centimeters; growing the sugar plant to an age of at least 4 months; harvesting the stalks of the sugar cane plant when the stalks have a length of 10 to 50 centimeters; cutting the harvested stalks into stalk segments, wherein the stalk segments are cut to a length of 1 to 5 centimeters; and planting one or more of the stalk segments into a planting container that has a volume from 10 to 200 cubic centimeters.

The invention provides an improved method for transformation of sorghum and the production of genetically modified sorghum. In particular, methods and means are described for the production of high quality, transformable sorghum plant cells which are maintained in culture for longer duration without losing their regenerative potential and their use for genetic transformation. The method also describes the use of improved media for efficient plant regeneration from transformed plant cells, thereby providing significant improvement in the stable transformation frequency of sorghum.
