      Epidermal cells are the cells on the surface of plants.

    8. anatomical analysis

      Anatomy is a branch of biology focusing on the structure of organisms or a certain part of organisms.

      Anatomical analysis is the analysis in such field. Here, the authors focus on the stucture of root cells.

    9. phenocopied

      Phenocopy means the plants grown under a certain condition have similar characteristics to the plants grown under a different condition.

    10. RAP2.12-GFP

      RAP2.12 (RELATED TO AP2 12) is a protein, of which the level increases when plants are under hypoxia condition. RAP2.12-GFP is a protein made by fusing RAP2.12 protein with GFP and is used to indicate whether hypoxia response is triggered in plants.

    11. pPCO2:GFP-GUS

      This is a GFP-based reporter indicating whether hypoxia response is activated in plants. The presence of green signals in roots means hypoxia response is activated.

    12. pPCO1:GFP-GUS

      pPCO1 means the promoter region of the gene PCO1 (PLANT CYSTEINE OXIDASE 1), which is required to turn PCO1 on. PCO1 gene is turned on under hypoxia condition, which is a indicator of hypoxia response in plants.

      Here, pPCO1 is fused with DNA sequences encodes GFP and GUS. Under hypoxia condition, pPCO1 turns on the production of GFP so scientists can determine if hypoxia response is activated in plants by visualizing GFP.

    13. hypoxia

      Hypoxia means a condition with not enough oxygen.

    14. root elongation zone

      Root elongation zone is a zone of roots where root cells are expanding.

    15. EIN3-GFP (green fluorescent protein)

      Green fluorescent protein is a protein that emits green light after absorbing light at a different wavelength. EIN3 (Ethylene-insensitive 3) is a protein, of which the level increases when plants' response to ethylene is triggered. EIN3-GFP is a protein made by fusing EIN3 protein with GFP and is used to indicate whether ethylene response is triggered in plants.

    16. bulk density (BD)

      Bulk density indicates the degree of soil compaction. it is calculated as the dry weight of soil per unit soil volume. The soil volume includes the volume of soil particles and the volume of soil pore space among particles.

    17. rhizosphere

      Rhizosphere is defined as the section of of soil surrounding plant roots, which contains chemicals released from plant roots and a population of microorganisms.

    18. wild-type

      Wild-type refers to individuals of a species that are in the typical form of that species and occur in nature.

    19. Arabidopsis

      Arabidopsis (Arabidopsis thaliana) is a plant species that is widely used as a model organism in plant research.

    20. mutant

      Mutants refer to individual organisms of a certain species that are considered "abnormal" when compared to normal individuals of the same species that occur in nature. Usually, in a mutant, at least one gene is artificially disrupted and does not function normally. Mutants are powerful tools to study the function of a gene.

    21. ethylene

      Ethylene is a gaseous plant hormone that regulates many plant activities such as fruit ripening, leaf development, responses to environmental stresses etc.

    1. phagocytosis

      The process where a cell engulfs a smaller particle (bacteria, smaller cells, etc) where it is trapped and subsequently defused.

    2. intrapleural pressure

      Pressure associated within the pleural cavity, the space enclosed by the pleura, which is a thin layer of tissue that covers the lungs and lines the interior wall of the chest cavity.

    3. nanotoxicology

      the study of adverse health effects of nanoscale (with sizes on the order of 10^-9 meters) particles.

    4. alveolar-capillary interface

      where exchange of gasses such as oxygen and carbon dioxide occurs between the tiny air sacs in lung (alveolus) and capillaries.

    5. microdevice

      A very small device, whose dimensions are on the micro scale (under 1mm). Often referenced in the context of biomechanical-electric system (bioMEM)

    6. cyclic mechanical strain

      The human body has lots of moving internal parts. Repeated and regular contractions caused by the movement of food through the intestines puts pressure on surrounding tissues. Another example is the human lungs expanding and contracting during breathing.

    7. translocation

      The movement of something (nanoparticles) from one place (alveolar) to another (capillary).
