Genetic dissection of the shoot and root ionomes of Brassica napus grown with contrasting phosphate supplies.

abstract：BACKGROUND AND AIMS:Although it was generally assumed that Maxillaria spp. do not produce nectar, in recent years, nectar has been reported for a number of these orchids. Nevertheless, our current understanding of nectary structure and nectar secretion in Maxillaria is based solely on M. coccinea (Jacq.) L.O. Williams ...
