Proline and serine affect polarity and development of carrot somatic embryos 

 -  Cell Differentiation, 17, p.193-198, 1985 .
<br/><br/> The time sequence of four different stages of development has been identified in carrot somatic embryos with an esterase staining technique as an early cytocbemical marker of commitment to stelar differentiation. A progressive determination of development from cotyledonary traces to hypocotyl and root tip, in this order, has been confirmed through specific blocks induced by serine and proline.
