花的发育是被子植物有性生殖的关键过程。花发育的最后阶段是胚珠的受精和果实的形成，这在生物学和经济学上都很重要。在这里，我们报告了超过1100个独特的拟南芥基因编码的已知和假定的转录因子（TF）在长角果发展过程中使用高密度过滤阵列杂交的表达谱。层次聚类分析揭示了不同角果发育阶段的不同表达谱。这使得这些表达谱的功能分类组，即雌蕊发育，胚胎发生，种子成熟，果实成熟，和果实发育。进一步的重点是MADS盒家族，其中包含许多功能良好的成员。这些MADS盒基因在角果发育过程中的表达谱为它们的功能和进化关系提供了额外的线索。
Flower development is a key process for all angiosperms and is essential for sexual reproduction. The last phase in flower development is fertilization of the ovules and formation of the fruits, which are both biologically and economically of importance. Here, we report the expression profiles of over 1100 unique Arabidopsis genes coding for known and putative transcription factors (TFs) during silique development using high-density filter array hybridizations. Hierarchical cluster analyses revealed distinct expression profiles for the different silique developmental stages. This allowed a functional classification of these expression profiles in groups, namely pistil development, embryogenesis, seed maturation, fruit maturation, and fruit development. A further focus was made on the MADS-box family, which contains many members that are functionally well-characterized. The expression profiles of these MADS-box genes during silique development give additional clues on their functions and evolutionary relationship.
