Sieve elements are a key component of phloem, the conductive tissue through which plants transport carbohydrates and a wide range of signalling molecules. Elongated cylindrical cells are capped at one ...

Seasonal collections of stems of various ages were made of Celastrus scandens L., Parthenocissus inserta (Kerner) Fritsch, and Vitis riparia Michx. In C. scandens, cambial activity, phloem ...

This is a preview. Log in through your library . Abstract Light microscopic studies of the petioles of Lagenaria siceraria reveal that the external phloem of each bicollateral vascular bundle develops ...

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 ...

Crops worldwide are increasingly vulnerable to pandemics, as diseases hitch rides on global flows of people and goods, hopping from continent to continent. Phloem diseases such as citrus greening are ...

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 ...

Sieve elements are a key component of phloem, the conductive tissue through which plants transport carbohydrates and a wide range of signalling molecules. Elongated cylindrical cells are capped at one ...

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 ...
