Question
Chapter 40, Problem 2IQ
Summary Introduction
To determine: If the plants will flower at different times in the absence of flower-repressing genes and the vernalization and autonomous pathway genes induced expression of flower-promoting genes.
Introduction: The flowering plants have four different flowering pathways which are genetically regulated. The pathways include the light-dependent pathway, temperature pathway, gibberellin-dependent pathway, and the autonomous pathway.

EXPERIMENT 4: INDUCTION OF CALLUS SOMATIC EMBRYOGENESIS OF HAPLOID PLANTS
Objective:
To prepare anther as a source of explant
To induce callus somatic embryogenesis of haploid plants
Procedure:
Cut off the buds and sort them into 3 developmental stages based on length of buds
Surface sterilize the buds in 70% ethanol for 2-3 minutes, making sure the entire bud is immersed in the alcohol.
Drain off excess alcohol from the buds and aseptically excise the anthers from each bud.
Remove the filaments and culture the anther on one of the agar media provided. Label the stage of development of the bud on each petri dish as the anthers are cultured. Seal the Petri dishes with parafilm.
Incubate in the dark at 26 to 28ºC for 4 to 8 weeks or until small plants can be seen growing out of the anthers. Then transfer to diffuse light.
Record the results of the experiment in table form and submit the report.
Observation:
The culture was contaminated after 8 weeks of incubation…
