Examination of nectar production in wild-type and cwinv4 flowers

	Wild-type	cwinv4-1	cwinv4-2
No. of flowers with nectara	250/250	0/250	0b/250

^aFlowers were examined for nectar droplets accumulating inside sepals surrounding lateral nectaries. A minimum of ten individual plants were examined for each line.

^bExtremely limited indications of fluid very rarely appeared inside the sepals of cwinv4-2 flowers; however, no nectar droplets ever accumulated inside the flowers of these plants. These findings are in line with the leaky expression of AtCWINV4 found within cwinv4-2.
