Journal ArticleDOI
Lignin and lignans in plant defence: insight from expression profiling of cinnamyl alcohol dehydrogenase genes during development and following fungal infection in Populus.
Agnieszka Bagniewska-Zadworna,Abdelali Barakat,Piotr Łakomy,Dariusz Jan Smoliński,Marcin Zadworny +4 more
TL;DR: expression analysis following inoculation with fungal pathogens, showed that five genes were induced in either stem or leaves, adding further evidence that CAD/CAD-like genes have evolved specialised functions in plant development and defence against various pest and pathogens.
Journal ArticleDOI
Avoiding transport bottlenecks in an expanding root system: Xylem vessel development in fibrous and pioneer roots under field conditions
Agnieszka Bagniewska-Zadworna,Julia Byczyk,David M. Eissenstat,Jacek Oleksyn,Marcin Zadworny +4 more
TL;DR: Compared to fibrous roots, rapid development of transport capacity in pioneer roots is not primarily caused by accelerated xylogenesis but by larger and more numerous tracheary elements and by rapid initiation of secondary growth.
Journal ArticleDOI
Physio-Genetic Dissection of Dark-Induced Leaf Senescence and Timing Its Reversal in Barley.
Ewa Sobieszczuk-Nowicka,Tomasz Wrzesinski,Agnieszka Bagniewska-Zadworna,Szymon Kubala,Renata Rucińska-Sobkowiak,Władysław Polcyn,Lucyna Misztal,Autar K. Mattoo +7 more
TL;DR: The organelle-specific physiology in and gene medleys during stress-induced barley leaf senescence are reversible prior to terminal programmed cell death phase and the mega-autophagy symptoms were apparent much later, specifically on day 10 of DILS, when disruption of organelles—nucleus and mitochondria —became evident.
Journal ArticleDOI
The root microtubule cytoskeleton and cell cycle analysis through desiccation of Brassica napus seedlings
TL;DR: It has been demonstrated that a small percentage decrease in relative humidity can cause irreparable changes in membrane permeability, as well as in nuclear structure and microtubule cytoskeleton stability.
Journal ArticleDOI
An extensin-rich matrix lines the carinal canals in Equisetum ramosissimum, which may function as water-conducting channels
Olivier Leroux,J. P. Knox,Bert Masschaele,Agnieszka Bagniewska-Zadworna,Susan E. Marcus,Myriam Claeys,L. Van Hoorebeke,Ronald L. L. Viane +7 more
TL;DR: The carinal canals in E. ramosissimum have a distinctive lining containing pectic homogalacturonan, cellulose, xyloglucan and extensin, which might function as water-conducting channels which would be especially important during the elongation of the internodes when protoxylem is disrupted and the metaxylesm is not yet differentiated.
