Affymetrix data from Populus nectaries versus leaves


ABSTRACT: To identify the genes encoding the defense proteins and gain a deeper insight into the Ptt nectary transcriptom, poplar DNA microarrays (Affymetrix) were hybridized with RNA of extrafloral nectaries and nectary-free leaf sections Many plant species grow extrafloral nectaries and produce nectar to attract carnivore arthropods as defenders against herbivores. We studied in Populus how insect feeding feeds back on nectary development and activity. Two nectary types evolved with Populus trichocarpa (Ptr) and P. tremula x P. tremuloides (Ptt) were studied from their ecology down to the genes and molecules. 3 samples of leaves and 3 of nectaries from P. tremula tremuloides field-culture

Many plant species grow extrafloral nectaries and produce nectar to attract carnivore arthropods as defenders against herbivores. Two nectary types that evolved with Populus trichocarpa (Ptr) and Populus tremula × Populus tremuloides (Ptt) were studied from their ecology down to the genes and molecules. Both nectary types strongly differ in morphology, nectar composition and mode of secretion, and defense strategy. In Ptt, nectaries represent constitutive organs with continuous merocrine nectar  ...[more]
