SUC1_ARATH | developmental stage | Transcripts accumulate in mature pollen before and during germination, but translation starts only when pollen germination initiates, and continues in pollen tubes. Expressed in cells surrounding the vascular bundle of the anther connective tissue, mostly at the dehiscence time. Also present in a ring of parenchymatic cells between the xylem vessels of the style (upper end of the transmitting tract toward which pollen tubes grow). Expressed in the epidermal cell layers of funiculi (at protein level). |
SUC1_ARATH | function | Responsible for the transport of sucrose into the cell, with the concomitant uptake of protons (symport system). This transport is both voltage- and energy-dependent. Can also transport other glucosides such as maltose, alpha-phenylglucoside and beta-phenylglucoside. May also transport biotin. Required for normal pollen germination and anthocyanin accumulation induced by sucrose. |
SUC1_ARATH | pathway | Glycan biosynthesis; sucrose metabolism. |
SUC1_ARATH | similarity | Belongs to the glycoside-pentoside-hexuronide (GPH) cation symporter transporter (TC 2.A.2.4) family. |
SUC1_ARATH | tissue specificity | Expressed in flowers (at protein level). Highly expressed in pollen. Expressed in pollen tubes and root vascular cylinder, pericycle and endodermis. |
