Auxin and self-organization at the shoot apical meristem.
Plants continuously generate new tissues and organs throughout their life cycle, due to the activity of populations of specialized tissues containing stem cells called meristems. The shoot apical meristem (SAM) generates all the aboveground organs of the plant, including leaves and flowers, and plays a key role in plant survival and reproduction. Organ production at the SAM occurs following pre...
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 کاملTHE EFFECTS OF SALT STRESS ON THE SHOOT APICAL MERISTEM AND LEAF GENIERATION IN SUNFLOWER (HELIANTNUS ANNUUS L.)
Sunflower (Helictnthur annuus L. cvs Mehr Shafagh) seedlings were grown in nutrient solutions containing 20.5 to 70.4 mM NaCl and 0 as the control. The effects of salinity on developmental changes occurring in the shoot apices of plants were studied. At 20.5 mM NaCI concentration, the leaf emergence rate and plastochron index of Shafagh increased significantly, but this phenomenon was not o...
متن کاملThe patterns of gene expression in the tomato shoot apical meristem.
In this paper, we describe the synthesis of a cDNA library from the vegetative shoot apical meristem and the analysis of clones selected from it. Using in situ hybridization, we characterized the patterns of expression of these genes in the tomato shoot apical meristem, as well as the patterns obtained from other sources. The results from the analysis of 15 cDNAs indicated the following six mai...
