The role of cell selection for pollen grain fertility after treatment of barley sprouts (Hordeum distichum L.) with UV-B irradiation

open access: yesActa Biologica Slovenica, 2011
UV-B irradiation of barley sprouts within the range of 0.5-4.3 kJ/m2 induced an increase in the number of chromosome aberrations in the root meristem and pathologies in the reproductive system.

[Retracted] Leaf Rolling and Stem Fasciation in Grass Pea (Lathyrus sativus L.) Mutant Are Mediated through Glutathione‐Dependent Cellular and Metabolic Changes and Associated with a Metabolic Diversion through Cysteine during Phenotypic Reversal

open access: yesBioMed Research International, Volume 2014, Issue 1, 2014., 2014
A Lathyrus sativus L. mutant isolated in ethylmethane sulfonate‐treated M2 progeny of mother variety BioL‐212 and designated as rlfL-1 was characterized by inwardly rolled‐leaf and stem and bud fasciations. The mutant exhibited karyomorphological peculiarities in both mitosis and meiosis with origin of aneuploidy.

Towards reconciliation of structure with function in plasmodesmata—who is the gatekeeper? [PDF]

open access: yes, 2000
Whilst the structure of higher plant plasmodesmata was first described by Robards (1963. Desmotubule—a plasmodesmatal substructure. Nature 218, 784), and despite many subsequent intensive investigations, there is still much that remains unclear relating ...
