Phloem diseases, including the economically devastating citrus greening, are particularly difficult to study because phloem cells -- essential for plant nutrient transport -- are difficult to access ...

High-molecular-weight fluorochromes were intracellularly injected into a sieve element of the fascicular stem phloem of Vicia faba L., using a modified membrane-potential-recording pressure probe.

Leaf vasculature plays a pivotal role in nutrient transport and leaf morphology. A new study in Brassica rapa reveals the developmental trajectories of vascular tissues in Chinese cabbage using single ...

1. A study was made comparing the effects of two phloem-limited viruses, curly top and aster yellows, using flax, Linum usitatissimum L., as the host plant. 2. The curly-top virus induces degenerative ...

Researchers monitored the progression of phloem production over time in field-grown HLB-affected citrus trees to determine how the trees are capable of sustaining new growth. Results showed that new ...

In vascular plants, long-distance transport of photoassimilates is driven by a pressure gradient within the phloem. It is a highly specialised tissue consisting of a network of living, tube-shaped ...

Owing to recent advances, plant vascular developmental can now be described from early specification during embryogenesis up to late differentiation events. Plant vascular tissues display both ...

LAKE ALFRED, FL--Citrus Huanglongbing (citrus greening disease) is highly destructive and fast-spreading, contributing to a reduction in crop yields in Florida and threatening the future of the citrus ...
