The phase transition of vegetative to reproductive growth in plants is regulated by various environmental factors including day length and light quality. Two Arabidopsis thaliana genes, VASCULAR PLANT ONE ZINC FINGER1 and VOZ2 mediated phyB-dependent flowering regulation. By mutant complementation assays, VOZ1 and VOZ2 expressed in vascular bundles functioned as transcriptional regulators in nucleus. Genetic and molecular researches suggested that VOZ1 and VOZ2 promote growth-phase transition to flowering by down-regulating FLC and its closely related homologs MAF1 to MAF5 by a pathway that is independent to vernalization pathway.

植物从营养生长到生殖生长的相变受多种环境因素的调控，包括日照长度和光照质量。两个拟南芥基因，维管植物1锌指1和VOZ2介导phyb依赖性开花调控。突变体互补实验表明，在维管束中表达的VOZ1和VOZ2在细胞核中起转录调控作用。遗传和分子研究表明，VOZ1和VOZ2通过下调FLC及其密切相关的同源物MAF1 - MAF5，通过独立于春化途径的途径促进生长阶段向开花阶段过渡。
