Wood formation in Angiosperms [PDF]

open access: yesComptes Rendus. Biologies, 2010
Wood formation is a complex biological process, involving five major developmental steps, including (1) cell division from a secondary meristem called the vascular cambium, (2) cell expansion (cell elongation and radial enlargement), (3) secondary cell wall deposition, (4) programmed cell death, and (5) heartwood formation. Thanks to the development of

A Small Guanosine Triphosphate Binding Protein PagRabE1b Promotes Xylem Development in Poplar

open access: yesFrontiers in Plant Science, 2021
Rab GTPases are the subfamily of the small guanosine triphosphate (GTP)-binding proteins which participated in the regulation of various biological processes. Recent studies have found that plant Rabs play some specific functions.

A Comparative Analysis of Transcription Networks Active in Juvenile and Mature Wood in Populus

open access: yesFrontiers in Plant Science, 2021
Juvenile wood (JW) and mature wood (MW) have distinct physical and chemical characters, resulting from wood formation at different development phases over tree lifespan.

Enzyme Complexes of Ptr4CL and PtrHCT Modulate Co-enzyme A Ligation of Hydroxycinnamic Acids for Monolignol Biosynthesis in Populus trichocarpa

open access: yesFrontiers in Plant Science, 2021
Co-enzyme A (CoA) ligation of hydroxycinnamic acids by 4-coumaric acid:CoA ligase (4CL) is a critical step in the biosynthesis of monolignols. Perturbation of 4CL activity significantly impacts the lignin content of diverse plant species.

Tree Growth Under Climate Change: Evidence From Xylogenesis Timings and Kinetics

open access: yesFrontiers in Plant Science, 2020
Tree growth is one of the most studied aspects of tree biology, particularly secondary growth. In the Mediterranean region, cambial activity is mostly determined by water availability.

Flammability behaviour of wood and a review of the methods for its reduction [PDF]

open access: yes, 2013
Wood is one of the most sustainable, aesthetically pleasing and environmentally benign materials. Not only is wood often an integral part of structures, it is also the main source of furnishings found in homes, schools, and offices around the world.

Beech wood treated with polyglycerol succinate: a new effective method for its protection and stabilization [PDF]

open access: yes, 2020
This paper deals with an original and non-biocidal chemical treatment consisting of a vacuum/pressure impregnation step of beech wood with a water-borne mixture made from heat-activated condensation of succinic anhydride (SA) and glycerol (G).

Xylem plasticity in Pinus pinaster and Quercus ilex growing at sites with different water availability in the Mediterranean region: relations between Intra-Annual Density Fluctuations and environmental conditions. [PDF]

open access: yes, 2020
Fluctuations in climatic conditions during the growing season are recorded in Mediterranean tree-rings and often result in intra-annual density fluctuations (IADFs).

Heterologous over-expression of ACC SYNTHASE8 (ACS8) in Populus tremula x P. alba clone 717-1B4 results in elevated levels of ethylene and induces stem dwarfism and reduced leaf size through separate genetic pathways

open access: yesFrontiers in Plant Science, 2014
Plant height is an important agronomic and horticultural trait that impacts plant productivity, durability and esthetic appeal. A number of the plant hormones such as gibberellic acid (GA), auxin and ethylene have been linked to control of plant ...

Cambial Activity of Moringa peregrina (Forssk.) Fiori in Arid Environments

open access: yesFrontiers in Plant Science, 2021
Moringa peregrina (Forssk.) Fiori, one of 13 species of the Moringaceae family widely distributed throughout the dry tropics, has the potential to become one of the most economically important medicinal plants in Egypt. However, despite its tolerance for
