Variation in xylem vessel diameter is one of the most important parameters when evaluating
plant water relations. This review provides a synthesis of the ecophysiological implications …

With the completion of the Populus trichocarpa genome sequence and the development of
various genetic, genomic, and biochemical tools, Populus now offers many possibilities to …

Wood (also termed secondary xylem) is the most abundant biomass produced by plants,
and is one of the most important sinks for atmospheric carbon dioxide. The development of …

The plant vascular system, composed of xylem and phloem, evolved to connect plant organs
and transport various molecules between them. During the post‐embryonic growth, these …

Plant cell walls provide structural support for growth and serve as a barrier for pathogen
attack. Plant cell walls are also a source of renewable biomass for conversion to biofuels …

Abstract KNOTTED1 (KN1)-like homeobox (KNOX) transcription factors are involved in the
establishment and maintenance of plant meristems; however, few direct targets of KNOX …

Secondary growth from vascular cambia results in radial, woody growth of stems. The
innovation of secondary vascular development during plant evolution allowed the …

Plant biomass used for cellulosic biofuel production is primarily from vegetative tissues.
Therefore, an increase in the vegetative growth of plants will lead to a higher production of …

The formation of secondary cell walls in cell types such as tracheary elements and fibers is a
defining characteristic of vascular plants. The Arabidopsis transcription factor KNAT7 is a …

Abstract Background Auxin/Indole-3-Acetic Acid (Aux/IAA) and Auxin Response Factor
(ARF) transcription factors are key regulators of auxin responses in plants. We identified the …
