I am new in the field of plant nutrition and I am searching for the most relevant markers to use to follow N and P starvation in Arabidopsis (both in shoots and roots). What are the most sensitive markers and those that would NOT be modulated by other signals (like microbial signals for example)? I thank you in advance for your help.
After response you, highly appreciate for your work in plant nutrition field, according your request, recently I download several research on impact of macro nutrition on growth and production crops.
Please sent me your email and I share the paper with you.
Best regards ✨
You might start with root high-affinity transporters for corresponding nutrients, for example, PHT1 and NRT1. Whether they are modulated by other signals are separate issues, as there are many connections between physiology of plant nutrition and disease responses, as you are well aware of.
Please consider chemical analysis for acid extractable phosphate and for a suitable form of mineral N related o what you are supplying, e.g., nitrate
