Limb morphogenesis: connections between patterning and growth

Limb development is a complex process involving precise control of both patterning and growth. Great strides have been made in understanding limb morphogenesis and identifying essential patterning genes in Drosophila. Differential expression of these genes divides the future limb into territories, which will give rise to different regions of the adult appendage. Recent analyses have defined the...

Regulation of mandibular growth and morphogenesis.

The development of the vertebrate face is a dynamic process that starts with the formation of facial processes/prominences. Facial processes are small buds made up of mesenchymal masses enclosed by an epithelial layer that surround the primitive mouth. The 2 maxillary processes, the 2 lateral nasal processes, and the frontonasal processes form the upper jaw. The lower jaw is formed by the 2 man...

Environmental control of microbial growth and morphogenesis.

changes that are often associated with changes in physiology. One of the men who has worked on this subject a great deal will give the next pap~r on this program, Or. Walter J. Nickerson is Professor of Microbial Biochemistry at the Institute of Microbiology, Rutgers University. I do not believe Dr. Nickerson has invented or created a fungus , but he certainly has manipulated them in very inter...

hmgA, transcriptionallyactivated byHpdA, in£uences the biosynthesis ofactinorhodin inStreptomyces coelicolor

Homogentisate 1,2-dioxygenase (HmgA) converts homogentisate to maleylacetoacetate in the pathway of tyrosine catabolism in living organisms. Studies published to date have not elucidated the transcriptional regulation of hmgA and its biological function in Streptomyces spp. Here it is shown that the transcription of hmgA in Streptomyces coelicolor was activated by HpdA, an AsnC-type activator, ...
