Microscopic studies on modified wall structure and lignin topochemistry in xylem fibres of poplar after wounding

open access: yesMaderas: Ciencia y Tecnología, 2014
Information about fine structure following wounding in differentiating xylem tissue is still scarce. This study provides information on cell wall modifications with special emphasis on lignin distribution in xylem fibres of poplar differentiating at the

The plant hormone auxin directs timing of xylem development by inhibition of secondary cell wall deposition through repression of secondary wall NAC‐domain transcription factors

open access: yesPhysiologia Plantarum : An International Journal for Plant Biology, 2018
Wood formation in higher plants is a complex and costly developmental process regulated by a complex network of transcription factors, short peptide signals and hormones.

Eucalyptus gunnii CCR and CAD2 promoters are active in lignifying cells during primary and secondary xylem formation in Arabidopsis thaliana [PDF]

open access: yes, 2006
cited By 21International audienceCell-specific expression patterns of the Eucalyptus gunnii cinnamoyl coenzymeA reductase (EgCCR) and cinnamyl alcohol dehydrogenase (EgCAD2) promoters were analyzed by promoter-GUS histochemistry in the primary and ...

Contrasting xylem vessel constraints on hydraulic conductivity between native and non-native woody understory species

open access: yesFrontiers in Plant Science, 2013
We examined the hydraulic properties of 82 native and non-native woody species common to forests of Eastern North America, including several congeneric groups, representing a range of anatomical wood types.

Genome-Wide Identification of Differentially Expressed Genes Associated with the High Yielding of Oleoresin in Secondary Xylem of Masson Pine (Pinus massoniana Lamb) by Transcriptomic Analysis

open access: yesPLoS ONE, 2015
Masson pine is an important timber and resource for oleoresin in South China. Increasing yield of oleoresin in stems can raise economic benefits and enhance the resistance to bark beetles.

Why are Chloris gayana leaves shorter in salt-affected plants? Analyses in the elongation zone [PDF]

open access: yes, 2006
Reduced hydraulic conductance calculated from growth data was suggested to be the main reason for reduced leaf expansion in salt-stressed Chloris gayana (Rhodes grass). In this work, xylem vessel cross-sections and wall enzyme activities were analysed to

‘Paedomorphosis’ and ‘juvenility’ in secondary xylem: (not such) useful constructs?

open access: yesIAWA Journal, 2023
Summary In 1962 Carlquist published “A Theory of Paedomorphosis in Dicotyledonous Woods” based on his observations that some species of non-tree growth forms such as stem succulents, lianas, woody herbs, and tree rosettes exhibit, in their secondary xylem, cellular characteristics more commonly associated with primary xylem.

The papain-like cysteine protease CEP1 is involved in programmed cell death and secondary wall thickening during xylem development in Arabidopsis

open access: yesJournal of Experimental Botany, 2018
The papain-like cysteine protease CEP1 is involved in clearing cellular contents during programmed cell death and regulating secondary wall thickening during xylem development.

Fit to Exponential from A simple mathematical model of allometric exponential growth describes the early three-dimensional growth dynamics of secondary xylem in Arabidopsis roots [PDF]

open access: yes, 2019
Unravelling the specific growth dynamics of key tissues and organs is fundamental to understand how multicellular organisms orchestrate their different growth programmes.
