Vascular plants, also known as tracheophytes or higher plants, are a large group of plants have lignified tissues (the xylem) and non-lignified tissue (the phloem). Vascular plants include the clubmosses, horsetails, ferns, gymnosperms and angiosperms....

It has also been suggested that autophagy is involved in dPCD of suspensor cells in somatic embryos51, as well as in the tracheary elements of the xylem52 and the anther tapetum8, implying a common role for autophagy in promoting dPCD in different cell types. Timely PCD of the anther ...
xylem fibers, and parenchyma cells with different functions are present. Tracheary elements in xylem are dead at maturity, while sieve elements in phloem are still-living cells lacking certain organelles, such as nuclei, mitochondria, and plastids [5]. The unique characteristics and heterogeneity of...
Experimental evidence suggests that plants can repair embolized xylem by pushing water from living vessel-associated cells into the gas-filled conduit lumina. Most surprisingly, embolism refilling is known to occur even when the bulk of still functioning xylem is under tension, a finding that is in...
International Water Institute. Xylem is proud to be a founding sponsor and champion of the program for the past 25 years. Over that time, the initiative has inspired and empowered 125,000 youth innovators around the world to bring their bold ideas to solve the world’s greatest wat...
