CO2 regulates stomata opening

Stomata, the pores on the underside of the leaf, let CO2 in for photosynthesis and water vapour out. Now researchers show that by an increasing of CO2 in the atmosphere plants are not using this to fix more energy but for saving water.

Stomata done differently

Stomata are the pores formed by kidney shaped cells. But in some plants like succulents, they look a little bit different and have these accompanying “wingmen” cells. Now a new study in Science Advances found clues for their function and how they are formed.

Potential for regeneration

For a long time, the question was if all plant cells could develop into embryo’s or that only specific cells can do that. Now a group of international researchers show in their latest article that only specific cells have this possibility to develop into embryo’s.

Counting stomata

Counting stomata Stomata close after they receive a calcium current. How quickly, that is dependent on the trigger of this current. But how the stomata distinguishes those calcium signals was up till now unknown. A recently in Current Biology published study shows how stomata differentiate between the different signals. By using a light activated calciumContinue reading “Counting stomata”
