Sentence:  We suggest that this ability of roots to incorporate microbes be termed <WSD>rhizophagy</WSD> to reﬂect the apparent active uptake mechanism. 
Meaning of the word marked with <WSD> tags:  The degradation of symbiotic microbes within root cells; 'rhizophagy symbiosis', or 'rhizophagy cycle', is a cyclic process whereby plants obtain nutrients from symbiotic bacteria that alternate between a root intracellular endophytic phase and a free-living soil phase. Bacteria acquire soil nutrients in the free-living soil phase; nutrients are extracted from bacteria oxidatively in the intracellular endophytic phase.
