A subgroup of homeobox genes, which play an important role in the developmental processes of a variety of multicellular organisms, Hox genes have been shown to play a critical role in vertebrate pattern formation. Hox genes can be thought of as general purpose control genes―that is, they are similar in many organisms and direct the same processes in a variety of organisms, from mouse, to fly, to human.

* Provides researchers an overview and synthesis of the latest research findings and contemporary thought in the area

* Inclusion of chapters that discuss the evolutionary development of a wide variety of organisms

* Gives researchers and clinicians insight into how defective Hox genes trigger developmental abnormalities in embryos

PIF4 is involved in elongation-growth responses in a variety of light responses and also in response to increased temperatures (Huq and Quail, 2002; Koini et al., 2009; Lorrain et al., 2008; 2009; Stavang et al., 2009). The variety of conditions in which PIF4 modulates growth is paralleled by a great complexity of PIF4 regulation. The control of PIF4 activity includes interaction with the DELLA proteins and LONG HYPOCOTYL in FR (HFR1) to prevent it from binding to DNA, transcriptional regulation

WUS lead to misspecification of stem cells and premature termination of the SAM (Laux et al., 1996). WUS is initially expressed at the 16-cell stage of embryogenesis in the four subepidermal cells of the apical domain (Mayer et al., 1998). Through subsequent rounds of asymmetric cell division, WUS expression becomes confined to the deeper OC region of the developing SAM. It is still unclear how WUS is initially activated during embryogenesis. Because the plant hormone cytokinin (CK) acts to

et al., 2006; Li et al., 2005; Xu et al., 2006). However, as the leaves of such double mutants largely retain correct adaxial–abaxial polarity, additional redundancies or differences in the patterning of the TAS3 ta-siRNA pathway and downstream targets must exist in Arabidopsis as compared to maize, rice, and Lotus. Localization of TAS3 ta-siRNA pathway components reveals that tasiR-ARF biogenesis in Arabidopsis is restricted to the two adaxial most cell layers of developing leaf primordia.
