Identification of direct targets of FUSCA3, a key regulator of Arabidopsis seed development.
FUSCA3 (FUS3) is a B3 domain transcription factor that is a member of the LEAFY COTYLEDON (LEC) group of genes. The LEC genes encode proteins that also include LEC2, a B3 domain factor related to FUS3, and LEC1, a CCAAT box-binding factor. LEC1, LEC2, and FUS3 are essential for plant embryo development. All three loss-of-function mutants in Arabidopsis (Arabidopsis thaliana) prematurely exit em...

Pollen tube contents initiate ovule enlargement and enhance seed coat development without fertilization
In angiosperms, pollen tubes carry two sperm cells toward the egg and central cells to complete double fertilization. In animals, not only sperm but also seminal plasma is required for proper fertilization. However, little is known regarding the function of pollen tube content (PTC), which is analogous to seminal plasma. We report that the PTC plays a vital role in the prefertilization state an...
متن کاملRegulation of ovule development.
Ovule development in Arabidopsis and other plants has been the focus of classic and molecular genetic analyses in recent years. This has been an exciting time to be involved in plant developmental biology, because many genetic pathways and regulatory mechanisms have been elucidated. Continued studies of ovule mutants have contributed to and benefited from these advances. Ovule development invol...
متن کاملBELL1 and AGAMOUS genes promote ovule identity in Arabidopsis thaliana.
Molecular and genetic analyses have demonstrated that the Arabidopsis thaliana gene BELL1 (BEL1) is required for proper morphogenesis of the ovule integuments. Several lines of evidence suggest that BEL1 may act, at least in part, to repress the function of the organ identity gene AGAMOUS (AG) during ovule development. To study the relative roles of BEL1 and AG, plants homozygous for ag, bel1 o...
