TL;DR: The results of these studies have been reported with the aim to provide further insight into connections between plants and nanomaterials.
Abstract: Nanomaterials and nanotechnology have been widely applied in the world in this last decade. Nanotechnology provides the tool and the technological platforms for the study and transformation of biological systems. Few studies have focused on the effects and mechanisms of nanomaterials on plants. The results of these studies have been reported with the aim to provide further insight into connections between plants and nanomaterials.

TL;DR: The author discusses the terminology, the presence of B-chromosomes in animals and plants, and their principal cytogenetic characteristics.
Abstract: SUMMARYThe author intends to give this as a contribution in the discussion relating to a non-homogeneous group of chromosomes, variously known as accessory, B, extra or supernumerary. The term B-chromosome is considered the most appropriate. Moreover, the author discusses the terminology, the presence of B-chromosomes in animals and plants, and their principal cytogenetic characteristics.

TL;DR: The most common mechanism of polyploidization acting in plant tissues and cells appears to be supernumerary chromosome reproduction, which is responsible for polysomaty in root and shoot meristems as well as forpolyploidy in any type of differentiated tissues and for nuclear growth in general.
Abstract: SUMMARYThe actually available data on the occurrence of polyploidy in plant tissues and cells have been critically reviewed. The incidence of polyploidy in the plant body, the cytological mechanisms by which the polyploid condition is produced, the physiological and general significance of polyploidy in the « soma » of plant organisms and related questions have been considered.The most common mechanism of polyploidization acting in plant tissues and cells appears to be supernumerary chromosome reproduction. This is responsible for polysomaty in root and shoot meristems as well as for polyploidy in any type of differentiated tissues and for nuclear growth in general. During the development of ephemeral tissues, such as the anther tapetum, supernumerary chromosome reproduction has been sometimes found to occur intermingled with monochromosome mitoses and/or typical endomitosis of the Gerris-type.Abortive mitoses due to spindle disturbances and chromosome stickiness or both are a very common polyploidization...
