Selaginella genome analysis – entering the ‘homoplasy heaven’ of the MADS world
Frontiers in Plant Science, 2012 In flowering plants, arguably the most significant transcription factors regulating development are MADS-domain proteins, encoded by Type I and Type II MADS-box genes. Type II genes are divided into the MIKCC and MIKC* groups. In angiosperms, these types

SALL4 Expression in Gonocytes and Spermatogonial Clones of Postnatal Mouse Testes [PDF]
, 2013 The spermatogenic lineage is established after birth when gonocytes migrate to the basement membrane of seminiferous tubules and give rise to spermatogonial stem cells (SSC). In adults, SSCs reside within the population of undifferentiated spermatogonia (

Epigenetic control of cell identities from epiblast to gastrulation
The FEBS Journal, Volume 292, Issue 20, Page 5259-5287, October 2025.In this review, we present and contextualize current knowledge about the roles of epigenetic modifiers during the development of mouse epiblast to gastrulation stage. The epigenetic regulation of enhancer and promoter elements by DNA methylation, histone modifications, and chromatin accessibility in concert with lineage‐specific transcription factors ...

EvoDevo, 2011 Background Mammals as a rule have seven cervical vertebrae, except for sloths and manatees. Bateson proposed that the change in the number of cervical vertebrae in sloths is due to homeotic transformations. A recent hypothesis proposes that the number of

SUPERMAN, a regulator of floral homeotic genes in Arabidopsis [PDF]
, 1992 We describe a locus, SUPERMAN, mutations in which result in extra stamens developing at the expense of the central carpels in the Arabidopsis thaliana flower.

APETALA2 antagonizes the transcriptional activity of AGAMOUS in regulating floral stem cells in Arabidopsis thaliana. [PDF]
, 2017 APETALA2 (AP2) is best known for its function in the outer two floral whorls, where it specifies the identities of sepals and petals by restricting the expression of AGAMOUS (AG) to the inner two whorls in Arabidopsis thaliana.

Cloning and analysis of two Ceratopteris thalictroides MADS-box genes
上海师范大学学报. 自然科学版, 2014 MADS-box transcription factors,as a large gene family,play an important role in plant growth and development,especially act as key regulators in controlling the identities of floral organs in flowering plants.They are also significant in the evolutionary

Mitochondrial genetics of alloplasmic male-sterile Brassica napus lines [PDF]
, 2005 Reliable and economical production of hybrid (F1) varieties requires efficient means to control pollination. The predominant system for pollination control of most field crops today is cytoplasmic male sterility (CMS).
