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 ...

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 ...

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 ...

To establish productive infection, plant viruses need to be able to efficiently invade and spread within a plant. Most viruses are introduced into a plant via the epidermal or mesophyll cells where ...
