Regulation and Physiological Significance of the Nuclear Shape in Plants
The shape of plant nuclei varies among different species, tissues, and cell types. In Arabidopsis thaliana seedlings, nuclei in meristems and guard cells are nearly spherical, whereas those of epidermal cells in differentiated tissues are elongated spindle-shaped. The vegetative nuclei in pollen grains are irregularly shaped in angiosperms. In the past few decades, it has been revealed that several nuclear envelope (NE) proteins play the main role in the regulation of the nuclear shape in plants. Some plant NE proteins that regulate nuclear shape are also involved in nuclear or cellular functions, such as nuclear migration, maintenance of chromatin structure, gene expression, calcium and reactive oxygen species signaling, plant growth, reproduction, and plant immunity. The shape of the nucleus has been assessed both by labeling internal components (for instance chromatin) and by labeling membranes, including the NE or endoplasmic reticulum in interphase cells and viral-infected cells of plants. Changes in NE are correlated with the formation of invaginations of the NE, collectively called the nucleoplasmic reticulum. In this review, what is known and what is unknown about nuclear shape determination are presented, and the physiological significance of the control of the nuclear shape in plants is discussed
乳幼児期自閉症スペクトラム児の母親における困難への対処に伴う体験のプロセス
The processes experienced by mothers of young children with Autism Spectrum Disorders(ASD) when dealing with difficulties were examined. Interviews were conducted withmothers (N= 8 ) of young children with ASD, and the results were qualitatively analyzedusing the Modified Grounded Theory Approach, which indicated the following process of theirexperience. ( 1 ) Mothers gradually come to understand their children by dealing withdifferent difficulties in child-rearing specific to children with ASD.( 2 ) Mothers experiencepsychological and behavioral changes, including feelings about the characteristics andbehavioral problems of their children, and measures to deal with these behavioral problems.( 3 ) Mothers expect support from specialists as an environmental factor that facilitating theabove process. Moreover, the results suggested that emotional support from surroundingpeople such as spouses, relatives, friends, parents’ association members, and someone to talkto, among others, was considered useful for the mothers
