CSAT Antibody Interferes with in Vivo Migration of Somitic Myoblast Precursors into the Body Wall
An involvement of the fibronectin receptor in muscle cell behavior has been demonstrated previously only in vitro (Chiquet et al., 1979; Neff et al., 1982; Greve and Gottlieb, 1982; Turner et al., 1983). By graft...

Rice (Oryza sativa L.): Factors Affecting Androgenesis
The frequency of the induction of androgenesis in cultured anthers in general is rather low. In order to utilize anther culture in crop breeding programmes, it is essential that the haploids are produced in la...

Chapter
Embryo Culture
The search for ideal trees with desirable characteristics has been on for many decades with the hope of using those trees to generate progenies or rooted cuttings. These propagules are needed to reforest the v...
