Phloem specialisation
Webb1 juli 2008 · The phloem tissue lies between these radiating arcs of xylem, generating a central structure known as the vascular cylinder ... This differential distribution clearly reflects phloem specialization for the downward and upward transport of virus, as previously described for other virus–host interactions (Andrianifahanana et al., ... WebbOverall, increased cell specialization in multicellular organisms provides a significant evolutionary advantage by allowing the organisms to adapt to their changing environments more effectively. 4. Multicellularity Enables Larger Body Size And More Complex Structures, Leading To Increased Survival Advantages. By allowing cells to come together ...

Gentianales. The order Gentianales (commonly consisting of the families Loganiaceae, Gentianaceae, Saccifoliaceae, Apocynaceae, and Asclepiadaceae; Retziaceae has been occasionally included in this order) is ancestral to the other orders in the subclass Asteridae. The superior ovary (i.e., …
WebbWe found that cellular specification is mediated near the stem cell niche by PHLOEM EARLY DOF (PEAR) transcription factors. However, the PEAR dependent differentiation … Webb17 apr. 2024 · Two phloem-mobile sugars, sucrose and trehalose 6-phosphate (Tre6P), have, for instance, been implicated in the control of shoot branching, as their levels increase in buds upon apex decapitation (Mason et al., 2014; Fichtner et al., 2024) and Arabidopsis plants with altered levels of Tre6P show distinct branching phenotypes …
WebbThe mechanisms that allow cells in the plant meristem to coordinate tissue-wide maturation gradients with specialized cell networks are critical for indeterminate growth. Here, we reconstructed the protophloem developmental trajectory of 19 cells from cell birth to terminal differentiation at single cell resolution in the Arabidopsis root. WebbThey eventually mature in order to perform various roles within the plant body. The greatest examples of secondary xylem and secondary phloem to describe the redifferentiation process are secondary xylem and secondary phloem. The secondary xylem on the inside and secondary phloem on the exterior emerge from the dedifferentiated vascular …
