Flower Development in Gerbera Hybrida, Asteraceae
As a genetically determined structure, flower is an attractive object for developmental studies in plants. Flower development provides a good system for understanding cell differentiation and genetic mechanisms needed for organogenesis. The current molecular view on flower development has been based on studies on relatively few model species, like Arabidopsis and Antirrhinum. Research in model ...
متن کاملPostharvest Assessment of Lignifying Enzymes Activity, Flower Stem Lignification and Bending Disorder of Gerbera Cut Flower
Scape bending disorder is the most important factor affecting postharvest loss of gerbera cut flowers. One of the ultimate reasons for gerbera stem bending is lignin, with deformation structural functions and defensive mechanisms. This postharvest experiment was conducted to evaluate the role of phenylalanine ammonia lyase (PAL) and peroxidase (POD) enzymes activity in stem bending of two gerbe...
متن کاملFunctional role of peroxidase gene in the resistance of the cut gerbera flower (Gerbera jamesonii) to stem bending disorder
Peroxidase is one of the most important genes in the lignin biosynthesis pathway. Polymerization of the phenolic derivatives into lignin, a connection between cell wall polymers such as monolignules, consequently, cell wall strength are the main functions of this enzyme. Accordingly, endogenous POD gene was isolated and cloned into gateway expression vector (PK7WG2) containing CAMV 35S promoter...

متن کاملHeads and tails: evolution of antero-posterior patterning in insects.
In spite of their varied appearances, insects share a common body plan whose layout is established by patterning genes during embryogenesis. We understand in great molecular detail how the Drosophila embryo patterns its segments. However, Drosophila has a type of embryogenesis that is highly derived and varies extensively as compared to most insects. Therefore, the study of other insects is inv...
