Do nitrogen limitation and high density responses in rice suggest a role for ethylene under high density stress?
High density stress has similar but greater impact on plant growth and development compared to nitrogen limitation. Global transcriptome changes implicate ethylene as a volatile signal used to communicate proximity in under dense population growth condition and suggest a role for phytohormones in high density stress response in rice plants.
We suggest that these patients are best managed conservatively unless further hazard to the fetus or mother appears.
