Abstract Unlike plants in the field, which experience significant temporal fluctuations in environmental conditions, plants in the laboratory are typically grown in controlled, stable environments. Therefore, signaling pathways evolved for survival i

Shoot-to-root mobile CEPD-like 2 integrates shoot nitrogen status to systemically regulate nitrate uptake in Arabidopsis

Autor: Ryosuke Ota, Yuri Ohkubo, Yasuko Yamashita, Mari Ogawa-Ohnishi, Yoshikatsu Matsubayashi

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-9 (2020)

Plants regulate nitrate uptake in roots to meet nitrogen demand in shoots. Here Ota et al. identify CEPDL2, a polypeptide that is induced during nitrogen deficiency in leaves, and show that it moves via the phloem to promote high-affinity nitrate upt

Peptide ligand-mediated trade-off between plant growth and stress response

Deciding whether to grow or to divert energy to stress responses is a major physiological trade-off for plants surviving in fluctuating environments. We show that three leucine-rich repeat receptor kinases (LRR-RKs) act as direct ligand-perceiving re

A type 2C protein phosphatase activates high-affinity nitrate uptake by dephosphorylating NRT2.1

Autor: Yuri Ohkubo, Keiko Kuwata, Yoshikatsu Matsubayashi

Publikováno v: Nature plants. 7(3)

The nitrate transporter NRT2.1, which plays a central role in high-affinity nitrate uptake in roots, is activated at the post-translational level in response to nitrogen (N) starvation1,2. However, the critical enzymes required for the post-translati

Shoot-to-root mobile polypeptides involved in systemic regulation of nitrogen acquisition

Autor: Mina Tanaka, Yuri Ohkubo, Yoshikatsu Matsubayashi, Mari Ogawa-Ohnishi, Ryo Tabata

Publikováno v: Nature plants. 3

Plants uptake nitrogen (N) from the soil mainly in the form of nitrate. However, nitrate is often distributed heterogeneously in natural soil. Plants, therefore, have a systemic long-distance signalling mechanism by which N starvation on one side of
