Cellular parameters of the shoot apical meristem in Arabidopsis.
The shoot apical meristem (SAM) is a small group of dividing cells that generate all of the aerial parts of the plant. With the goal of providing a framework for the analysis of Arabidopsis meristems at the cellular level, we performed a detailed morphometric study of actively growing inflorescence apices of the Landsberg erecta and Wassilewskija ecotypes. For this purpose, cell size, spatial d...
متن کاملStem cell regulation in the Arabidopsis shoot apical meristem.
The aerial structure of higher plants is generated dynamically throughout the life cycle through the activity of stem cells that are located at the growing shoot tip, the apical meristem. The stem cells continuously divide to renew themselves and provide cells for leaf, stem and flower formation. Stem cell maintenance is governed by intercellular communication between the apical stem cells and ...
متن کاملQuantification of growth at the shoot apical meristem of Arabidopsis
In the process of morphogenesis primordia of lateral organs, like leaves or flowers, are formed at the shoot apical meristem (SAM). In order to maintain the ability to organ formation, the SAM itself has to be self-perpetuated, i.e. its general shape and size have to be maintained, despite the fact that portions of SAM periphery are continuously used up for lateral organ formation. Thus growth ...
متن کاملOBE3 and WUS Interaction in Shoot Meristem Stem Cell Regulation
The stem cells in the shoot apical meristem (SAM) are the origin of all above ground tissues in plants. In Arabidopsis thaliana, shoot meristem stem cells are maintained by the homeobox transcription factor gene WUS (WUSCHEL) that is expressed in cells of the organizing center underneath the stem cells. In order to identify factors that operate together with WUS in stem cell maintenance, we per...
متن کاملThe mitochondrial protease AtFTSH4 safeguards Arabidopsis shoot apical meristem function
The shoot apical meristem (SAM) ensures continuous plant growth and organogenesis. In LD 30 °C, plants lacking AtFTSH4, an ATP-dependent mitochondrial protease that counteracts accumulation of internal oxidative stress, exhibit a puzzling phenotype of premature SAM termination. We aimed to elucidate the underlying cellular and molecular processes that link AtFTSH4 with SAM arrest. We studied At...
