MADS-domain transcription factors are a large family of
regulators that have keyfunctions in plant development as: floral
transition, inflorescence and flower meristem specification, root
development, gametogenesis,
embryo, fruit and seed
development, etc.

In this work, we analyzed the involvement of a new MADS-box gene
XAL2/AGL14 inflowering time transition. For this end, we used two
different mutant alleles and an overexpression line.

Flowering time of XAL2 mutants and overexpression line in short
and long days conditions. xal2-1 and xal2-2 alleles are late
flowering inboth photoperiods, in the same manner as soc-1-3 and
agl24-2, on the other hand, overexpression line is early flowering.
Bolting time, was measured as days required for the stem to develop
1 cmlong after seed sowing under either photoperiod condition.
