Living beings need elements to develop properly. The study of ionomics measures and analyses the element accumulations in living organisms to determine which mineral nutrients are required and not required for growth. Associate Professor Toshihiro Watanabe from Hokkaido University’s Research Faculty of Agriculture applies this approach to learn about mineral accumulation in both plants and soil, in addition to inter-element interactions.
Endosperm culture in Haemanthus albiflos
22 Jan 2021
Scientists at Hokkaido University and Chiba University have developed simultaneous triploid and hexaploid varieties of Haemanthus albiflos by the application of endosperm culture, thus extending the use of this technique.

Environmental changes trigger tiny RNA segments to modify plant pores involved in photosynthesis.
07 Feb 2020
A research team from the Centre for Genomic Studies on Plant-Environment Interaction for Sustainable Agriculture and Food Security recently found that some non-coding RNA can produce very short proteins (small peptides), which play an important role in regulating organismal development and stress resistances. The findings challenge the very definition of non-coding RNAs and may open a new research path for future drug and crop improvement. The research article has been published in the journal Plant Physiology. (See note)

Plants overcome hunger with the aid of autophagy
12 Mar 2018
Researchers at Tohoku University have found that plants activate autophagy in their leaf cells to derive amino acids that are used for survival under energy-starved “hunger” conditions. The findings show that amino acid utilization in plants can be controlled by the manipulation of autophagy.
