    Notes: A 72-year-old woman had suffered from parapsoriasis en plaque (large plaque type) controlled by topically applied psoralen ultraviolet A (PUVA) therapy. The parapsoriasis lesions gradually disappeared, but numerous tiny red papules with pruritus appeared over the forearms and lower legs 120 days after starting PUVA therapy. These papules developed to form violaceous plaques. Histological findings demonstrated the characteristics of lichen planus. Two months later, tense bullae developed on the plaques and on uninvolved skin of the limbs. These were subepidermal, with linear deposits of IgG and C3 along the basement membrane zone (BMZ) in immunofluorescence of peribullous skin, and immunodeposits of type IV collagen along the floor of the bullae. We therefore, diagnosed lichen planus pemphigoides (LPP). Using systemic and topical steroid therapy, the lesions rapidly resolved and there has been no recurrence. This case suggests that the combination of basal cell injuries caused by chronic inflammation and PUVA therapy could expose BMZ components to autoreactive lymphocytes and induce LPP.

    Notes: Background We identified five Cryptomeria japonica trees producing Cry j 1 isoforms that cannot be detected in a sandwich ELISA using two monoclonal antibodies, J1B01 and J1B07, suggesting that the binding affinity of these isoforms for both monoclonal antibodies is low.Objectives The binding properties of the Cry j 1 isoforms produced by five trees to J1B07 and J1B01 were examined. The complementary DNA (cDNA) sequences of the Cry j 1 isoforms were also determined.Methods To clarify the binding properties of these Cry j 1 isoforms to J1B01 and J1B07, Cry j 1 was quantified in pollen samples collected from each of the five trees, by sandwich ELISAs using polyclonal antibodies and either J1B01 or J1B07. The cDNA sequences of isoforms with different binding properties were determined. To test the assumption that amino acid substitutions affect the binding affinities of Cry j 1 isoforms for monoclonal antibodies, cleaved amplified polymorphic sequences (CAPS) markers representing the putative polymorphisms were used to analyse additional trees.Results Four of the five trees produced Cry j 1 isoforms with extremely low binding affinity for J1B07, whereas the other tree produced two different isoforms with low binding affinity for either J1B01 or J1B07. Cry j 1-encoding cDNA sequences for one of the four trees and for the exceptional fifth tree indicate that amino acid substitutions at positions 55 and 352 in mature Cry j 1 affect its binding to J1B01 and J1B07, respectively. This was supported by the results of CAPS analysis.Conclusion The existence of Cry j 1 isoforms with low binding affinity for either J1B01 or J1B07 was established. Furthermore, a single amino acid substitution is involved in this difference in binding affinity for each monoclonal antibody.

    Notes: Abstract  Linkage of RAPD markers to a single dominant gene for resistance to pine needle gall midge was investigated in Japanese black pine (Pinus thunbergii). Three primers that generated linked markers were found after 1160 primers were screened by bulked segregant analysis. The distances between the resistance gene, R, and the marker genes OPC06580, OPD01700, and OPAX192100 were 5.1 cM, 6.7 cM and 13.6 cM, respectively. OPC06580 was in coupling phase to R, whereas OPD01700 and OPAX192100 were in repulsion phase to R. A linkage map for a resistant tree was constructed using 96 macrogametophytes. In linkage analysis, 98 out of 127 polymorphic markers were assigned to 17 linkage groups and six linked pairs. The total length of this map was 1469.8 cM, with an average marker density of 15.6 cM. The genome length was estimated to be 2138.3 cM, and the derived linkage map covered 67.5% of the genome. Although the linked markers OPC06580, OPAX192100, and OPD01700, belonged to the same linkage group, no precise positions were found for OPC06580 or OPD01700.
