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.

A new and distinct cultivar of Poinsettia plant named ‘BKPONVW’, characterized by its broadly upright and uniformly mounding plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; large and full inflorescences with white-colored flower bracts; and excellent post-production longevity.

A new and distinct cultivar of Chamaesyce plant named ‘Dochastaduclewhi’, characterized by its relatively compact, mounding to semi-trailing plant habit; moderately vigorous growth habit; freely branching habit; freely flowering habit; and inflorescences with multiple white-colored flower bracts.

Methods of propagating and growing poinsettias in pots have allowed poinsettias to become the highest selling potted flowering plant. The present application relates generally to the field of plant propagation. In particular, a method of producing a pre-pinched, callused poinsettia cutting is provided. Also provided is a method to produce a poinsettia with improved growth habit. The invention also provides a pre-pinched, callused poinsettia cutting.

A new poinsettia plant particularly distinguished by having a low vigor, wider growth habit, white bract color, and more elongated bract shape, is disclosed.

A new and distinct cultivar of Poinsettia plant named ‘LAZZPO1615’, characterized by its compact, upright “V”-shaped and uniformly mounding plant habit; moderately vigorous growth habit; freely branching habit and strong stems; dark green-colored leaves; full inflorescences with medium to large bright red-colored flower bracts; and excellent post-production longevity.

A new poinsettia plant particularly distinguished by having a medium-high vigor, 60 day response time, and obtuse leaf shape, is disclosed.

A new and distinct cultivar of Poinsettia plant named ‘QS47’, characterized by its compact, upright and uniformly mounding plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; dense inflorescences with numerous curly and yellow-colored flower bracts; and excellent post-production longevity.

A new and distinct cultivar of Poinsettia plant named ‘QS44’, characterized by its compact, upright and uniformly mounding plant habit; moderately vigorous to vigorous growth habit; freely branching habit; dark green-colored leaves; large and full inflorescences with numerous vivid red-colored flower bracts; and excellent post-production longevity.
