Removal of Direct Red 23 from aqueous solution using corn stalks: Isotherms, kinetics and thermodynamic studies
Fathi MR
Spectrochimica Acta. Part A, Molecular and Biomolecular Spectroscopy, 364-372 (2015)
Dongbo Shi et al.
Development (Cambridge, England), 146(1) (2019-01-11)
A reduced rate of stem cell division is considered a widespread feature which ensures the integrity of genetic information during somatic development of plants and animals. Radial growth of plant shoots and roots is a stem cell-driven process that is
Extensive Natural Variation in Arabidopsis Seed Mucilage Structure

Frontiers in Plant Science, 7 (2016)
Pavel Veselý et al.
Annals of botany, 126(2), 323-330 (2020-06-01)
The idea that genome (size) evolution in eukaryotes could be driven by environmental factors is still vigorously debated. In extant plants, genome size correlates positively with stomatal size, leading to the idea that conditions enabling the existence of large stomata
Julien Moukhtar et al.
PLoS computational biology, 15(2), e1006771-e1006771 (2019-02-12)
Plant tissue architecture and organ morphogenesis rely on the proper orientation of cell divisions. Previous attempts to predict division planes from cell geometry in plants mostly focused on 2D symmetric divisions. Using the stereotyped division patterns of Arabidopsis thaliana early
