Expression and promoter analysis of BnaC4.BOR1;1c in B-efficient and B-inefficient cultivars. a Phenotypic performance of B-efficient cultivars (QY 10 and Ningyou 7) and B-inefficient cultivars (W10 and Bakow) that were cultivated in a hydroponic culture under B-limitation conditions (0.25 μM) for 10 d. b Sequence alignment of BnaC4.BOR1;1c promoters from two cultivars. c A 27-bp insertion in the region from − 451 bp to − 478 bp in the QY10 promoter that harbours four important cis-acting elements predicted using PLACE. Expression of BnaC4.BOR1;1c in (d) shoots and (e) roots from QY10 and W10; the plants were grown in 10 μM boric acid for 7 d, then transplanted in 0.25 μM B to analyse the expression after 1, 3, 12, 24, 48, and 72 h of treatment
