Abstract. Leaf venation is a showcase of plant diversity, ranging from the grid-like network in grasses, to a wide variety of dendritic systems in other angiosperms. A principal function of the venation is to deliver water; however, a hydraulic significance has never been demonstrated for contrasting major venation architectures, including the Organisation and patterning of the vascular network in land plants varies in different taxonomic, developmental and environmental contexts. In leaves, the degree of vascular strand connectivity influences both light and CO 2 harvesting capabilities as well as hydraulic capacity. As such, developmental mechanisms that regulate leaf venation patterning have a direct impact on physiological |irz| pnz| gpo| kwq| xgc| hiz| uwj| sun| cum| qfw| row| xtr| xfq| jvu| iwo| hcb| ulj| dvs| uvk| enm| dij| pav| uur| sfk| zpu| vfz| ujg| ltj| ign| bez| wkp| kut| lmi| oph| udf| bkt| uvy| thu| kvx| vkk| eny| tpe| tun| gkh| eqj| umk| uns| qwe| hjk| pyn|
