Proline affects the size of the root meristematic zone in Arabidopsis [PDF]
, 2015 We reported previously that root elongation in Arabidopsis is promoted by exogenous proline, raising the possibility that this amino acid may modulate root growth.

Shaping the meristem by mechanical forces [PDF]
F1000 Biology Reports, 2009 A recent report shows that cells in the Arabidopsis apical meristem orientate their cortical microtubules along mechanical stress patterns generated during tissue morphogenesis. This in turn is expected to influence the mechanical properties of the cell via the modification of the cortical microtubule network and the cell wall.

Commercial scale genetic transformation of mature seed embryo explants in maize
Frontiers in Plant Science, 2022 A novel, efficient maize genetic transformation system was developed using Agrobacterium-mediated transformation of embryo explants from mature seeds. Seeds from field grown plants were sterilized and crushed to isolate embryo explants consisting of the ...

Feedback from tissue mechanics self-organizes efficient outgrowth of plant organ [PDF]
Biophys. J. (2019) 117: 1995-2004, 2020 Plant organ outgrowth superficially appears like the continuous mechanical deformation of a sheet of cells. Yet, how precisely cells as individual mechanical entities can act to morph a tissue reliably and efficiently into three dimensions during outgrowth is still puzzling especially when cells are tightly connected as in plant tissue.

Timing of Nucleolar Activity in Meristems [PDF]
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

Genetic regulation of lateral root development
Plant Signaling & Behavior, 2023 Lateral roots (LRs) are an important part of plant root systems. In dicots, for example, after plants adapted from aquatic to terrestrial environments, filamentous pseudorhizae evolved to allow nutrient absorption. A typical plant root system comprises a

Combined in silico/in vivo analysis of mechanisms providing for root apical meristem self-organization and maintenance. [PDF]
, 2012 Background and aimsThe root apical meristem (RAM) is the plant stem cell niche which provides for the formation and continuous development of the root.

Trafficking and localization of KNOTTED1 related mRNAs in shoot meristems
Communicative & Integrative Biology, 2022 Multicellular organisms use transcripts and proteins as signaling molecules for cell-to-cell communication. Maize KNOTTED1 (KN1) was the first homeodomain transcription factor identified in plants, and functions in maintaining shoot stem cells.

Semiparametric modeling of autonomous nonlinear dynamical systems with application to plant growth [PDF]
Annals of Applied Statistics 2011, Vol. 5, No. 3, 2078-2108, 2011 We propose a semiparametric model for autonomous nonlinear dynamical systems and devise an estimation procedure for model fitting. This model incorporates subject-specific effects and can be viewed as a nonlinear semiparametric mixed effects model. We also propose a computationally efficient model selection procedure. We show by simulation studies that
