New York, USA, is an important regional center of processing carrot ( Daucus carota ssp. sativus ) production on ∼2223 acres annually ( US Department of Agriculture 2017 ). The roots are a rich source of carotenoids, vitamins, and dietary fiber
to have a higher proportion of nonfunctioning phloem as compared with ‘MM.106’ ( Rom and Carlson, 1987 ). As translocation of some minerals, such as phosphorus, occurs in the phloem ( Rom and Carlson, 1987 ), the nonfunctioning phloem in ‘M.9’ might
Huanglongbing or citrus greening is a devastating disease putatively caused by bacterium Candidatus Liberibacter asiaticus ( C Las) transmitted by an insect vector, the Asian citrus psyllid Diaphorina citri ( B ové, 2006 ). This phloem bacterium

emergence, seedlings were thinned to one plant per pot. Pots were lined with woven 20 × 20 mesh of 0.02-cm-diameter thread [about 0.016-cm 2 opening size (Clear Advantage Charcoal Fiber Glass Insect Screen; New York Wire, Hanover, PA)] and filled with a 2
possible remobilization of sugars via phloem sucrose transportation ( Ruan et al., 2010 ) between the perennial vine parts (the roots and trunk) and the ripening berries, thereby contributing to berry sugar accumulation ( Candolfi-Vasconcelos et al., 1994

Since the arrival of Huanglongbing (HLB), a.k.a. citrus greening in many citrus growing countries worldwide, citrus production continues to decline steadily. In Florida and in most other countries, HLB is associated with the phloem-limited bacterium
