Tracking seed water uptake in PR9920–171 and TARS-HT1 using iodine contrast and CT-scan imaging. Within one hour of soaking in iodine solution, a bright signal around the hilum was detected in both genotypes. At 2.5 h, a change was detected on the lens (arrow) of TARS-HT1 seeds which indicates the site of water entry in the seed coat. After 3 h of soaking, the water penetrated the whole seed coat of TARS-HT1 while PR9920–171 seeds remained unimbibed. The seeds of both genotypes were represented on the left as a reference. Several structures are distinguishable in legume seeds. H = hilum, L = Lens and M = micropyle
