On the air permeability of Populus pit [PDF]
, 2012 Sap hydrodynamics in vascular cells of trees seems to be controlled by small membranes called pits. Understanding how the pit junctions regulate the sap flow and stop embolism by cavitation is today a challenging issue.

Finding New Cell Wall Regulatory Genes in Populus trichocarpa Using Multiple Lines of Evidence. [PDF]
, 2019 Understanding the regulatory network controlling cell wall biosynthesis is of great interest in Populus trichocarpa, both because of its status as a model woody perennial and its importance for lignocellulosic products.

The physiological response of Populus tremula x alba leaves to the down-regulation of PIP1 aquaporin gene expression under no water stress. [PDF]
, 2013 In order to study the role of PIP1 aquaporins in leaf water and CO2 transport, several lines of PIP1-deficient transgenic Populus tremula x alba were generated using a reverse genetic approach. These transgenic lines displayed no visible developmental or

New Biotechnology, 2011 In the present study, interactions between the duration of treatment with auxin and different cytokinins and their effect on shoot regeneration were evaluated with the aim to establish a rapid and efficient in vitro regeneration method applicable to a variety of Populus species. Three different species, Populus angustifolia, P.

Genetics polymorphism of poplars from Moscow region based on high-throughput sequencing of ITS
Вавиловский журнал генетики и селекции, 2018 Poplars are widely used in landscaping of Moscow due to the ability to effectively purify the air from harmful impurities and to release a large amount of oxygen. The genus Populus is characterized by a high level of intraspecies polymorphism, as well as

Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa
Advanced Science, EarlyView.This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

Diversification and expression of the PIN, AUX/LAX, and ABCB families of putative auxin transporters in \u3cem\u3ePopulus\u3c/em\u3e [PDF]
, 2012 Intercellular transport of the plant hormone auxin is mediated by three families of membrane-bound protein carriers, with the PIN and ABCB families coding primarily for efflux proteins and the AUX/LAX family coding for influx proteins. In the last decade
