“…Medicago truncatula regulates the expression of sugar transport genes to modulate carbon allocation between the arbuscular mycorrhizal fungus Rhizophagus irregularis and the rhizobium Ensifer meliloti , adapting to different nutrient conditions (Kafle et al ., 2019). Also, plant‐mediated interactions between phloem‐feeding aphids and root‐parasitic nematodes have been investigated, revealing intricate mechanisms that involve various factors such as volatiles and hormones (Larson & Whitham, 1997; Heeren et al ., 2012; Hol et al ., 2016; Van Dam et al ., 2018; Shi et al ., 2022). However, the role of carbon allocation in such interactions between pests remains uncharted.…”
