new term: carpel anlagen

[Pankaj Jaiswal]

I need a new term to describe expression of DL gene in rice. The term is 
carpel anlagen.

definition: A presumptive region (carpel anlagen) on the floral 
meristem, where carpel primordia would initiate.

'DL expression was detected first in a few cells in the flower meristem 
at the lemma side (Figure 4E) and then in cells at the flank of the 
meristem (Figure 4F). These DL expression domains corresponded to the 
presumptive region (carpel anlagen), where carpel primordia would 
initiate. Shortly after this expression, carpel primordia began to form. 
At this stage, DL was expressed specifically and uniformly in carpel 
primordia (Figures 4G to 4I). No expression was detected in the flower 
meristem (Figures 4E and 4F) or the ovule primordium (Figures 4G to 4I). 
By contrast, expression of DL was not observed in dl-sup1 mutants 
throughout flower development (data not shown). Thus, the expression 
domains of DL are restricted to the carpel anlagen and the carpel 
primordia, and these expression patterns of DL are consistent with its 
specific role in carpel development.'
