In experiments on transport tissues in plants, researchers were able to identify factors of crucial importance for the formation of the plant tissue known as phloem. These factors differ from all ...

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 ...

A tiny region at the root tip has been found to be responsible for orchestrating the growth and development of the complex network of vascular tissues that transport sugars through plant roots. In a ...

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 ...

Ribonuclease LE (RNaseLE) from tomato (Lycopersicon esculentum Mill. cv. Lukullus) belongs to the widespread RNase T2 family of ribonucleases. With the exception of S-RNases of the solanaceous ...

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 ...

While the movement of water through xylem tissue is relatively well understood, the movement of solute-laden sap through phloem is not. One possibility is the ‘pressure flow hypothesis’ proposed by ...

Bark stripping is a common practice among many species of tree squirrels. Squirrels don’t actually eat the bark; they strip away the top layer to get to the sweet, phloem tissue underneath. Bark ...
