Studies on heteromorphic self-incompatibility systems: the cytochemistry and ultrastructure of the tapetum of Primula obconica.
This paper describes the cytochemistry and ultrastructure of the developing tapetum in Primula obconica, a plant with a heteromorphic, sporophytic self-incompatibility system. The tapetum is of the secretory type and cytochemical tests have shown that when it breaks down proteinaceous (esterase) and lipidic components are deposited on the developing pollen grains. Acid phosphatase, a marker of ...
متن کاملSelf‐ and intra‐morph incompatibility and selection analysis of an inconspicuous distylous herb growing on the Tibetan plateau (Primula tibetica)
There is discussion over whether pollen limitation exerts selection on floral traits to increase floral display or selects for traits that promote autonomous self-fertilization. Some studies have indicated that pollen limitation does not mediate selection on traits associated with either pollinator attraction or self-fertilization. Primula tibetica is an inconspicuous cross-fertilized plant tha...
متن کاملLarval Morph Variation in Chlosyne Lacinia (nymphalidae)
Mature larvae of the patch butterfly, Chlosyne lacinia (Geyer), exhibit striking color polymorphism. First described by T. D. A. Cockerell in Edwards (1893) and illustrated by Neck et aI. (1971), the three morphs are as follows: rufa, an all orange or orange-red form; nigra, an all black form; and bicolor, a form basically black as in nigra but with a prominent mid-dorsal row of orange to orang...
متن کاملQTL analysis of heterostyly in Primula sieboldii and its application for morph identification in wild populations.
BACKGROUND AND AIMS Primula sieboldii is a perennial clonal herb that is distributed around the Sea of Japan and is endangered in Japan. Its breeding system is characterized by heteromorphic self-incompatibility, and the morph ratio within a population is very important for reproductive success. The aims of this study were to construct a linkage map, map the S locus as a qualitative trait and q...
متن کاملGenetic Variation in Natural and Cultivated Populations of Primula Veris
Primula veris, a well-known pharmaceutical plant, is a long-lived perennial protected by law in Poland, so its rhizomes and roots can be collected as pharmaceutical stock only from cultivation. Genetic variation of three natural P. veris populations numbering 500–1200 individuals and of three cultivated populations derived from seeds collected from natural sites was investigated in respect of t...
