Gas exchange characteristics of Populus trichocarpa, Populus deltoides and Populus trichocarpa x P. deltoides clones

Tree Physiology, 1991
Responses of net photosynthesis, dark respiration, photorespiration, transpiration, and stomatal conductance to irradiance, temperature, leaf-to-air vapor density difference (VDD), and plant water stress were examined in two Populus trichocarpa clones (one from a moist, coastal climate in western Washington and one from a dry, continental climate in ...

Populus trichocarpa

2014
Populus trichocarpa Nisqually-1 is a clone of black cottonwood that is widely used as a model woody plant. It was the first woody plant to have a full genome sequence and remains today as the model for growth, metabolism, development, and adaptation for all woody dicotyledonous plants. It is one of the best-annotated plant genomes available. It is also

Evolution and diversity of invertase genes in Populus trichocarpa

Planta, 2007
Invertase (EC 3.2.1.26) plays a key role in carbon utilization as it catalyzes the irreversible hydrolysis of sucrose into glucose and fructose. The invertase family in plants is composed of two sub-families thought to have distinct evolutionary origins and can be distinguished by their pH optima for activity: acid invertases and neutral/alkaline ...

LEAF DIMORPHISM IN POPULUS TRICHOCARPA

American Journal of Botany, 1960
Critchfield, William B. (Pacific SW Forest & Range Expt. Sta., Berkeley, Calif.) Leaf dimorphism in Populus trichocarpa. Amer. Jour. Bot. 47 (8) : 699–711. Illus. 1960.—In Populus trichocarpa and other species of Populus, each tree bears 2 kinds of leaves, referred to here as “early” and “late” leaves. Both leaf types are present on all long shoots.

Genomewide analysis of the chitinase gene family in Populus trichocarpa

Journal of Genetics, 2013
The chitinase gene family is a large gene family in plants. As the first report of chitinase genes research on genome level in woody plants, here we report the identification of 37 Populus trichocarpa chitinase genes through a genomewide search. We divided these genes into five classes, based on sequence similarity and typical domain conservation.

Over-expression of DREB46 enhances drought tolerance in Populus trichocarpa

Journal of Plant Physiology, 2023
The drought responsive element binding (DREB) gene family has a significant role in plant abiotic stress responses. Here, we cloned a drought-inducible DREB gene, DREB46 (Potri.019G075500), and investigated its function in drought tolerance in Populus trichocarpa.

Characterization of the Expansin Gene Promoters in Populus trichocarpa

Forests
The expansin genes are commonly expressed in plant cells, and the encoded proteins influence plant growth and stress resistance by loosening the structure and increasing the flexibility of the cell wall. The objective of this study was to characterize expansin gene promoters in Populus trichocarpa to clarify the regulatory mechanisms underlying gene ...

Genome-wide identification, classification, and expression of phytocyanins in Populus trichocarpa

Planta, 2018
74 phytocyanin genes were identified in the Populus trichocarpa genome. Phylogenetic analysis grouped the PC proteins into four subfamilies (UCs, PLCs, SCs, and ENODLs). Closely related PC proteins share similar motifs, implying similar functions. Expression profiles of PtPC genes were analyzed in response to drought and salt-stress. Phytocyanins (PCs)

Genome-wide identification of NBS resistance genes in Populus trichocarpa

Plant Molecular Biology, 2008
As the largest class of disease resistance R genes, the genes encoding nucleotide binding site and leucine-rich repeat proteins ("NBS-LRR genes") play a critical role in defending plants from a multitude of pathogens and pests. The diversity of NBS-LRR genes was examined in the Populus trichocarpa draft genome sequence.

The Populus trichocarpa PtHSP17.8 involved in heat and salt stress tolerances

Plant Cell Reports, 2016
PtHSP17.8 was regulated by various abiotic stresses. Overexpression of PtHSP17.8 enhanced the tolerance to heat and salt stresses through maintain ROS homeostasis and cooperate with stress-related genes in Arabidopsis. Small heat shock proteins (sHSPs) play important roles in response to diverse biotic and abiotic stresses, especially in heat tolerance.
