Plant Physiology, Vol. 138, No. 2, Arabidopsis Special Issue (Jun., 2005), pp. 803-818 (16 pages) The growth of secondary xylem and phloem depends on the division of cells in the vascular cambium and ...

Journal of Experimental Botany, Vol. 40, No. 219 (October 1989), pp. 1069-1078 (10 pages) The minute changes in volume of a grape berry which occur from hour to hour were measured non-destructively in ...

Plants keep growing throughout their lives owing to the activity of stem cells in meristems 1. Genetic analyses have revealed key players such as ligands, receptors and transcription factors involved ...

These are distributed differently in roots and stems. In the root, the xylem forms a central column. It forms a solid support. The phloem is towards the centre, outside the xylem. Any green part of a ...

The phloem moves food substances that the plant has produced by photosynthesis to where they are needed for processes such as: Transport of substances in the phloem is called translocation. Phloem ...

Numerous insects and pathogens extract nutrients from phloem tissue buried deep inside plants. These phloem-feeding insects and pathogens cause tremendous economic losses worldwide and represent some ...

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 ...
