Epigenetics at the crossroads of secondary growth regulation [PDF]
Frontiers in Plant Science, 2022 The development of plant tissues and organs during post-embryonic growth occurs through the activity of both primary and secondary meristems. While primary meristems (root and shoot apical meristems) promote axial plant growth, secondary meristems ...

ACAULIS5 Is Required for Cytokinin Accumulation and Function During Secondary Growth of Populus Trees. [PDF]
Front Plant Sci, 2020 In the primary root and young hypocotyl of Arabidopsis, ACAULIS5 promotes translation of SUPPRESSOR OF ACAULIS51 (SAC51) and thereby inhibits cytokinin biosynthesis and vascular cell division.

Novel tools for quantifying secondary growth [PDF]
Journal of Experimental Botany, 2016 Secondary growth occurs in dicotyledons and gymnosperms, and results in an increased girth of plant organs. It is driven primarily by the vascular cambium, which produces thousands of cells throughout the life of several plant species. For instance, even in the small herbaceous model plant Arabidopsis, manual quantification of this massive process is ...

Photoperiod and temperature as dominant environmental drivers triggering secondary growth resumption in Northern Hemisphere conifers. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Forest trees can live for hundreds to thousands of years, and they play a critical role in mitigating global warming by fixing approximately 15% of anthropogenic CO2 emissions annually by wood formation.

Cytokinin signaling promotes root secondary growth and bud formation in Panax ginseng [PDF]
Journal of Ginseng ResearchBackground: Panax ginseng, one of the valuable perennial medicinal plants, stores numerous pharmacological substrates in its storage roots. Given its perennial growth habit, organ regeneration occurs each year, and cambium stem cell activity is necessary

Old-growth and secondary Araucaria Forest characterization
Trees, Forests and People, 2022 The Araucaria Forest is one of the most threatened ecosystems in Brazil due to selective logging and deforestation, mainly during the 20th century. The great majority of remnants are secondary forests with less than 50 ha, i.e., old-growth fragments are ...

Are the anatomical traits of stems and leaves good indicators of habitat specificity in closely related Myrtaceae species from Patagonia? [PDF]
Acta Botânica Brasílica, 2023 The anatomical attributes of young stems and leaves of newly formed shoots were studied for five Patagonian species of Myrtaceae: Amomyrtus luma, Ugni molinae, Luma apiculata, Myrceugenia exsucca and M. ovata var. nannophylla.

Effects of exogenous GA3 on stem secondary growth of Pinus massoniana seedlings.
Plant physiology and biochemistry : PPB, 2023 Gibberellins (GAs) play a crucial role in regulating secondary growth in angiosperms, but their effects on the secondary growth of gymnosperms are rarely reported. In this study, we administered exogenous GA3 to two-year-old P.
