| Abstract | We analyzed the effect of hydrostatic pressure at the 2–4 MPa level on the growth and organization of maize seedlings cells. At a pressure value of 2 MPa, we observed clarification of mitochondrial matrix, clusterization of endoplasmic reticulum elements with formation of ergastoplasm sites, and an increase of the number of small vacuoles in the cytoplasm. On the trans-side of dictyosomes, we revealed accumulation of vesicles with an electron-dense content, which indicates changes of transport in the endomembranous system. A decrease in the electronic density of tonoplast was accompanied by a reduction of the osmophilic inclusion amount in vacuoles. An elevation of pressure up to 4 MPa has been shown to cause destructive alterations in the tonoplast. None of the variants showed any destruction of the plasmalemma integrity, which was confirmed by staining with Evans blue. At a fall of the pressure to an atmospheric value, the frequency of structural disturbances of the tonoplast membrane was proportional to the pressure difference: minimum at a drop from 2 to 0 MPa and maximum at a drop from 4 to 0 MPa. Thus, it was concluded that the endomembranous system was among the targets of the pressure effect on the plant cells. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
