Heteromerization of Plant Aquaporins
The discovery of plasma membrane intrinsic protein (PIP) heterotetramerization has opened a new field of research. This phenomenon was first observed between PIPs belonging to two phylogenetic groups (PIP1 and PIP2) with ubiquitous expression in different plant tissues. These isoforms present few differences in their primary sequence but show major differences in their functionality when expres...
متن کاملAquaporins and plant water balance.
The impact of aquaporin function on plant water balance is discussed. The significance of these proteins for root water uptake, water conductance in the xylem, including embolism refilling and the role of plant aquaporins in leaf physiology, is described. Emphasis is placed on certain aspects of water stress reactions and the correlation of aquaporins to abscisic acid as well as on the relation...
متن کاملOn the pH regulation of plant aquaporins.
The majority of plants are unable to evade unfavorable conditions such as flooding, salinity, or drought. Therefore, a fine-tuned water homeostasis appears to be of crucial importance for plant survival, and it was assumed that aquaporins play a significant role in these processes. Regulation of plant aquaporin conductivity was suggested to be achieved by a gating mechanism that involves protei...
متن کاملPlant and Mammal Aquaporins: Same but Different
Aquaporins (AQPs) constitute an ancient and diverse protein family present in all living organisms, indicating a common ancient ancestor. However, during evolution, these organisms appear and evolve differently, leading to different cell organizations and physiological processes. Amongst the eukaryotes, an important distinction between plants and animals is evident, the most conspicuous differe...
متن کاملAquaporins and Water Permeability of Plant Membranes.
The mechanisms of plant membrane water permeability have remained elusive until the recent discovery in both vacuolar and plasma membranes of a class of water channel proteins named aquaporins. Similar to their animal counterparts, plant aquaporins have six membrane-spanning domains and belong to the MIP superfamily of transmembrane channel proteins. Their very high efficiency and selectivity i...
