During early postnatal periods, radial glial cells in various ventricular zones of the brain differentiate into ependymal cells and astrocytes. However, mechanisms that drive this time- and cell-specific differentiation remain largely unknown. Here, we show that expression of the forkhead transcription factor FoxJ1 in mice is required for differentiation into ependymal cells and a small subset of FoxJ1+ astrocytes in the lateral ventricles, where these cells form a postnatal neural stem cell niche. Moreover, we show that a subset of FoxJ1+ cells harvested from the stem cell niche can self-renew and possess neurogenic potential. Using a transcriptome comparison of FoxJ1-null and wild-type microdissected tissue, we identified candidate genes regulated by FoxJ1 during early postnatal development. The list includes a significant number of microtubule-associated proteins, some of which form a protein complex that could regulate the transport of basal bodies to the ventricular surface of differentiating ependymal cells during FoxJ1-dependent ciliogenesis. Our results suggest that time- and cell-specific expression of FoxJ1 in the brain acts on an array of target genes to regulate the differentiation of ependymal cells and a small subset of astrocytes in the adult stem cell niche.}, number={23}, journal={DEVELOPMENT}, author={Jacquet, Benoit V. and Salinas-Mondragon, Raul and Liang, Huixuan and Therit, Blair and Buie, Justin D. and Dykstra, Michael and Campbell, Kenneth and Ostrowski, Lawrence E. and Brody, Steven L. and Ghashghaei, H.

GENOTYPIC CORRELATION AND REPEATABILITY OF SOLUTION CULTURE AND GREENHOUSE SCREENING METHODS}, volume={30}, ISSN={["0011-183X"]}, DOI={10.2135/cropsci1990.0011183X003000050019x}, abstractNote={Breeding for Al tolerance in soybean [Glycine max (L.) Merr.], has been hindered by confusion regarding screening methodology. This study was undertaken to determine the relationship between greenhouse and solution culture screening methods, using 12 diverse soybean genotypes. Greenhouse media consisted of a Goldsboro sandy loam (fine‐loamy, siliceous, thermic Aquic Paledult) at 19% Al saturation and the same soil amended with Al2(SO4)3 to 55% Al saturation. Solution‐culture media consisted of 0 or 11 μM Al2(SO4)3 added to 200 μM CaSO4 solutions. Traits measured were shoot dry weight in greenhouse pots and radical elongation rate in solution culture. Aluminum tolerance was detected with both screening methods; however, unlike previous studies, agreement between methods was good (rG = 0.81), indicating that the solution‐culture screen does have some utility in plant breeding. The solution‐culture screen had a higher repeatability (0.78, based on six replications, compared with 0.54 for the greenhouse), further substantiating its utility. Two factors were critical in establishing the relationship between the two screens: (i) expression of Al tolerance as a percentage of the control and (ii) abundant replication in the greenhouse. Reliance on growth in Al alone as a measure of tolerance led to poor agreement between methods in our study and is not recommended for breeding purposes, except where the genetic population is very uniform morphologically. Earlier published studies of Al tolerance in the greenhouse may have suffered from inadequate replication.}, number={5}, journal={CROP SCIENCE}, author={CAMPBELL, KAG and CARTER, TE}, year={1990}, pages={1049–1054} }
