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 ...

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 ...

This is a preview. Log in through your library . Abstract “Candidatus Phytoplasma prunorum” (CPp) is a highly destructive phytopathogenic agent in many stone fruit-growing regions in Europe and the ...

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 ...

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 ...

So often we choose a tree because of its flowers, leaves, fall color or its fruit. Often, we forget about the bark. However, on many trees, the bark is the most interesting part of the tree. This can ...

Until not that long ago, scientists widely agreed on the evolutionary journey that plants took from the oceans to the land. They thought that algae evolved into mosses and their relatives, known as ...
