Collapsed auxin transport by iron inhibits primary root growth under low phosphate stress Under low phosphate stress, a burst of reactive oxygen species by accumulated iron suppresses the activity of PIN proteins, leading to a collapse of polar auxin transport and distribution in primary ...

#Arabidopsis root growth is known to be suppressed under low Pi conditions. Here, Zhang et al. report that this #growth inhibition is caused by the collapse of #auxin transport in the presence of accumulated iron.

Sodium butyrate regulates the sulfur respiration of rhizosphere soil to produce hydrogen sulfide modulating histone acetylation dynamics to enhance drought tolerance in rice Sodium butyrate increases the numbers of sulfate-reducing bacteria in the rice rhizosphere, stimulating hydrogen sulfide (H2S) biosynthesis. H2S represses the histone deacetylase OsHDA710, thereby el...
