DNA Methylation in Acacia mangium ln vitro and Ex-vitro buds, in relation to their within-shoot position, age and leaf morphology of the shoots [PDF]

open access: yes, 2009
DNA methylation was analyzed in Acacia mangium Willd. buds collected from in vitro and field growing shoots from the same clone and its juvenile offspring.

An Examination of the Correlation between Shoot Apical Meristem Size and leaf Heterophylly in Pisum sativum [PDF]

open access: yes, 2009
This study is a quantitative examination of the ramifications of leaf development as influenced by the size of the shoot apical meristem. I wish not to delve into a genetic examination of the shoot apical meristem but rather into the possible correlation

Floral induction and development in Myosotidium hortensia and Phormium cookianum : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Biology at Massey University, New Zealand [PDF]

open access: yes, 2004
Little is known of the stimuli needed for flowering in two New Zealand endemic plants, Myosotidium hortensia and Phormium cookianum. These plants are widely recognised by the horticulture sector and the concerns of this thesis were to aid understanding ...

Non-autonomy of AGAMOUS function in flower development: use of a Cre/loxP method for mosaic analysis in Arabidopsis [PDF]

open access: yes, 1998
Angiosperms use a multi-layered meristem (typically L1, L2 and L3) to produce primordia that then develop into plant organs, A number of experiments show that communication between the cell layers is important for normal development.

Transcriptional profiling of Medicago truncatula meristematic root cells

open access: yesBMC Plant Biology, 2008
Background The root apical meristem of crop and model legume Medicago truncatula is a significantly different stem cell system to that of the widely studied model plant species Arabidopsis thaliana. In this study we used the Affymetrix Medicago GeneChip®

Virus in Plant Apical Meristems

open access: yesJournal of General Virology, 1968
During the course of research on the growth of virus-free plants by culturing apical meristems removed from infected plants (D. G. A. Walkey & J. Fitzpatrick, in preparation), it was necessary to determine whether the virus was present in the meristems before they were cultured.

Metabolic aspects of organogenesis in the shoot apical meristem [PDF]

open access: yesJournal of Experimental Botany, 2006
Research over the last decade has led to tremendous advances in the characterization of the transcriptional networks involved in the initiation and maintenance of the shoot apical meristem (SAM), as well as the factors involved in the formation and development of leaves by this organ.

THE EFFECTS OF SALT STRESS ON THE SHOOT APICAL MERISTEM AND LEAF GENIERATION IN SUNFLOWER (HELIANTNUS ANNUUS L.) [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1996
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.

Toward a 3D model of phyllotaxis based on a biochemically plausible auxin-transport mechanism.

open access: yesPLoS Computational Biology, 2019
Polar auxin transport lies at the core of many self-organizing phenomena sustaining continuous plant organogenesis. In angiosperms, the shoot apical meristem is a potentially unique system in which the two main modes of auxin-driven patterning ...

Establishment of embryonic shoot–root axis is involved in auxin and cytokinin response during Arabidopsis somatic embryogenesis

open access: yesFrontiers in Plant Science, 2015
Auxin and cytokinin signaling participates in regulating a large spectrum of developmental and physiological processes in plants. The shoots and roots of plants have specific and sometimes even contrary responses to these hormones.
