In planta localisation patterns of MADS domain proteins during floral development in Arabidopsis thaliana [PDF]

open access: yes, 2009
Background: MADS domain transcription factors play important roles in various developmental processes in flowering plants. Members of this family play a prominent role in the transition to flowering and the specification of floral organ identity. Several

Ontogeny of the Maize Shoot Apical Meristem [PDF]

open access: yesThe Plant Cell, 2012
The maize (Zea mays) shoot apical meristem (SAM) arises early in embryogenesis and functions during stem cell maintenance and organogenesis to generate all the aboveground organs of the plant. Despite its integral role in maize shoot development, little is known about the molecular mechanisms of SAM initiation.

DNA synthesis in the nuclei of Pinus silvestris embryos during

open access: yesActa Societatis Botanicorum Poloniae, 2015
DNA synthesis starts earliest in the apical meristem of the shoot, and latest in the cotyledons. Mitoses appear simultaneously in the apical meristem and in the hypocotyl cortex.

Local expression of expansin induces the entire process of leaf development and modifies leaf shape [PDF]

open access: yes, 2001
Expansins are a family of extracellular proteins proposed to play a key role in wall stress relaxation and, thus, in cell and tissue growth. To test the possible function of expansins in morphogenesis, we have developed a technique that allows transient ...

Transcriptome analysis of tomato flower pedicel tissues reveals abscission zone-specific modulation of key meristem activity genes. [PDF]

open access: yesPLoS ONE, 2013
Tomato flower abscises at the anatomically distinct abscission zone that separates the pedicel into basal and apical portions. During abscission, cell separation occurs only at the abscission zone indicating distinctive molecular regulation in its cells.

Epigenetic regulation in the shoot apical meristem

open access: yesCurrent Opinion in Plant Biology, 2022
Epigenetic mechanisms form the basis of cellular memory, developmental decisions, and the cellular immune system that defends against transposons and viruses. Organs develop from the shoot apical meristem (SAM) to shape the plant's areal phenotype, and stem cells in the SAM serve as a functional germline.

Analysis of chlorophyll fluorescence reveals stage specific patterns of chloroplast-containing cells during Arabidopsis embryogenesis [PDF]

open access: yes, 2010
http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-97602010000100012&lng=es&nrm=isoThe basic body plan of a plant is established early in embryogenesis when cells differentiate, giving rise to the apical and basal regions of the embryo.

Concentration and Timing of Dikegulac Sodium on Helianthus hybrida ‘Sunfinity’ Seedlings for Potted Plant Production

open access: yesHortScience, 2022
Sunflower ‘Sunfinity’ (Helianthus hybrida) can be produced as a potted plant if apical dominance is removed with a manual pinch to control plant height and promote branching and flower number. Chemical pinching agents such as dikegulac sodium could prove

Dose dependence of morphological changes and aberration to the plantation of pine in the Chernobyl NPP exclusion zone [PDF]

open access: yesЯдерна фізика та енергетика, 2009
Dose rates to the Scots pine’ (Pinus sylvestris L.) apical meristem at three experimental sites were calculated. The morphological and cytogenetic changes of the trees were estimated, and the dependences of these changes on the dose rates to the apical ...

Shoot Apical Meristem Size Measurement

open access: yesBio-Protocol, 2016
The shoot apical meristem (SAM) is a collection of cells that continuously renew themselves by cell division and also provide cells to newly developing organs.
