Ion channels regulate nitrogen–potassium balance

Liu et al. reveal that anion channel SLAH3 forms complexes with potassium channels GORK and SKOR to modulate membrane potential via coordinating nitrogen–potassium balance. By Beibei Liu and Kai He Ministry of Education Key Laboratory of Cell Activities and Stress Adaptations, School of Life…

MtNRT2.1 controls root nodule formation in response to the ambient nitrate concentration

Luo et al. investigate how nitrate transporters direct root nodule formation in a legume. By Zhenpeng Luo & Fang Xie CAS Center for Excellence in Molecular Plant Sciences, Shanghai Institute of Plant Physiology and Ecology, Chinese Academy of Sciences, Shanghai, China.  Background: Nitrogen…

NLP7-CRF-PIN, the nitrate-cytokinin-auxin crosstalk module, conveys root nitrate signals and regulates shoot growth adaptive responses (PNAS)

Nitrate, the prominent form of nitrogen used by most land plants, is a signal regulating plant growth and development. Nitrate sensing by roots not only regulates root development to facilitate nutrient foraging, but also the growth of distant plant organs. Cytokinin is a mobile signal coordinating nitrate…

How do legumes decide where to get nitrogen––from the soil or from nitrogen-fixing bacteria?

Misawa, Ito, et al. explore how nitrate transporters and NIN-like protein transcription factors repress nodulation in the presence of exogenous nitrate. Momoyo Ito, Takuya Suzaki Faculty of Life and Environmental Sciences, University of Tsukuba, Tsukuba, Ibaraki, Japan  Background Through…
