Organogenesis at the Shoot Apical Meristem [PDF]
Plants, 2018 Lateral organ initiation at the shoot apical meristem involves complex changes in growth rates and directions, ultimately leading to the formation of leaves, stems and flowers. Extensive molecular analysis identifies auxin and downstream transcriptional regulation as major elements in this process.

Sterol gene expression in Arabidopsis [PDF]
, 2009 Sterols are recognized as playing vital roles in plant development, as has been demonstrated from mutational studies. The study of the hydra mutants of Arabidopsis provides new tools to dissect sterol function in development at the molecular genetic ...

The patterns of gene expression in the tomato shoot apical meristem
, 1993 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 ...

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis
Advanced Science, EarlyView.In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.

Timing of Nucleolar Activity in Meristems
Journal of Cell Science, 1972 ABSTRACT The nucleoli in 4 regions of the root meristem of Zea mays have been examined and the time spent in each of the phases of the nucleolar cycle has been calculated from estimates of the rates of mitosis and the fraction of cycling cells in each region. The nucleolar cycles have been fitted to the mitotic cycles of cycling cells in

Activation of Basal Cells of the Apical Meristem during Sepal Formation in Tomato
, 1994 Although great advances have been made in research on the regulation of primordium fate in the floral meristem, our understanding of the molecular events occurring during the floral transition remains incomplete.

The BnTFL1‐BnJAM3‐BnSWEETs Module Orchestrates Seed Storage Reserve Accumulation in Brassica napus
Advanced Science, EarlyView.BnaC03.TFL1 and BnaA01.JAM3 form a complex that facilitates the transport of soluble sugars from the seed coat to the embryo by directly activating the expression of BnSWEETs. Furthermore, BnaC03.TFL1 and BnaA01.JAM3 work cooperatively to promote soluble sugar and oil production while suppressing protein deposition.

Autoreproductive cells and plant meristem construction: The case of the tomato cap meristem [PDF]
Protoplasma, 2001 Root apical meristems are composed of two zones in which either formative or proliferative cell divisions occur. Within the formative zone, autoreproductive initial cells (a-cells) occupy distinctive locations. By means of graph-L-systems, the behavior of one such type of a-cells has been investigated, with particular reference to root caps within the ...

Advanced Science, EarlyView.ABSTRACT Viruses often hijack host developmental programs to promote infection, but the mechanistic links between reproductive regulation and antiviral immunity remain incompletely understood. Here, we identify a virus‐triggered hierarchical degradation cascade that links antiviral immunity and fertility regulation in rice. We show that the rice grassy
