strigolactones and the Regulation of Pea Symbioses in Response to Nitrate and Phosphate Deficiency

引用

Molecular Plant 2013年第1期6卷 76-87页

New roles for the recently identified group of plant hormones, the strigolactones, are currently under active investigation. One of their key roles is to regulate plant symbioses. These compounds act as a rhizosphere signal in arbuscular mycorrhizal symbioses and as a positive regulator of nodulation in legumes. The phosphorous and nitrogen status of the soil has emerged as a powerful regulator of strigolactone production. However, until now, the potential role of strigolactones in regulating mycorrhizal development and nodulation in response to nutrient deficiency has not been proven. In this paper, the role of strigolactone synthesis and response in regulating these symbioses is examined in pea （Pisum sativum L.）. Pea is well suited to this study, since there is a range of well-characterized strigolactone bio- synthesis and response mutants that is unique amongst legumes. Evidence is provided for a novel endogenous role for strigolactone response within the root during mycorrhizal development, in addition to the action of strigolactones on the fungal partner. The strigolactone response pathway that regulates mycorrhizal development also appears to dif- fer somewhat from the response pathway that regulates nodulation. Finally, studies with strigolactone-deficient pea mutants indicate that, despite strong regulation of strigolactone production by both nitrogen and phosphate, strigolac- tones are not required to regulate these symbioses in response to nutrient deficiency.

Influx and Efflux of strigolactones Are Actively Regulated and Involve the Cell-Trafficking System

引用

Molecular Plant 2015年第12期8卷 1809-1812页

作者： Dear Editor Department of Chemistry University of Turin via P. Giuria 7 10125 Torino Italy

strigolactones （SLs） are plant hormones that regulate different aspects of plant development. In roots, SLs are involved in the regulation of lateral-root formation and they induce root-hair elongation （Kapulnik et al., 2011）. They are also exuded from plant roots and act as stimulators of parasitic and symbiotic （e.g., arbuscular mycorrhizae） interactions. SLs are perceived in plants by a specific reception system that consists of several interacting proteins （reviewed by AI-Babili and Bouwmeester, 2015）.
