Editing Inflorescence (section)

====Genetic basis====
Genes that shape inflorescence development have been studied at great length in ''[[Arabidopsis]]''. ''LEAFY'' (LFY) is a gene that promotes [[Meristem|floral meristem]] identity, regulating inflorescence development in ''Arabidopsis.''<ref name=":1">{{Cite journal|last1=Shannon|first1=S.|last2=Meeks-Wagner|first2=D.

Studies have been recently conducted or are ongoing for homologs of these genes in other flower species.
