Since 1999, various forward-and reverse-genetic approaches have uncovered nearly 200
genes required for symbiotic nitrogen fixation (SNF) in legumes. These discoveries …

Abstract Sugars Will Eventually be Exported Transporters (SWEETs) have important roles in
numerous physiological mechanisms where sugar efflux is critical, including phloem …

The SWEET (sugars will eventually be exported transporter) family was identified as a new
class of sugar transporters that function as bidirectional uniporters/facilitators and facilitate …

Soil nutrient acquisition and exchanges through symbiotic plant–fungus interactions in the
rhizosphere are key features for the current agricultural and environmental challenges …

Plants have evolved a multitude of strategies to adjust their growth according to external and
internal signals. Interconnected metabolic and phytohormonal signalling networks allow …

Plant breeders have developed crop plants that are resistant to pests, but the continual
evolution of pathogens creates the need to iteratively develop new control strategies …

In plants, the root is a typical sink organ that relies exclusively on the import of sugar from the
aerial parts. Sucrose is delivered by the phloem to the most distant root tips and, en route to …

In legume nodules, symbiosomes containing endosymbiotic rhizobial bacteria act as
temporary plant organelles that are responsible for nitrogen fixation, these bacteria develop …

Key message Present review describes the structure, evolution, transport mechanism and
physiological functions of SWEETs. Their application using TALENs and CRISPR/CAS9 …

Plants form a mutualistic symbiosis with arbuscular mycorrhizal (AM) fungi, which facilitates
the acquisition of scarce minerals from the soil. In return, the host plants provide sugars and …
