Can anyone help:

I want to take photos of arabidopsis rosettes everyday as they grow to get growth curves for a lot of ecotypes. Does anyone know of software that can be used to read the label from inside the photo and rename the file with the plant ID and then amend the date to the file name too?

Rho-GTPase overexpression can impact the development of cell shape and airspace structure in Arabidopsis.

These genetic changes can also reduce photosynthesis, due to lower mesophyll conductance

A chlorophyll fluorescence-based biofeedback system was developed to adjust LED intensity based on real-time plant responses, rather than using a fixed photosynthetic photon flux density (PPFD). The system was tested in a growth chamber with lettuce and cucumber.
