Project description:Polystichum acrostichoides is a perennial, evergreen fern, commonly found in woodlands, stream banks, and rocky slopes in eastern North America. We present the whole genome sequence of this species. Illumina sequencing was performed on a leaf tissue sample from a single plant collected in Maryland, USA. The reads were assembled using a de novo method followed by a finishing step using series of references from related species. The raw and assembled data are publicly available via GenBank: Sequence Read Archive (SRR18053988) and Genome Assembly (JAOYMV000000000).
Project description:Background and aimsAlthough some taxonomic studies in the genus Trigonella have been conducted, there has been no concerted effort to study the breeding system. This paper examines the floral structure and pollination system in a population of T. balansae, an annual pasture legume.MethodsFloral morphology, hand and vector pollination, stigma receptivity, pollen tube growth, using scanning electron and fluorescence microscopy, were conducted.Key resultsMeasurements of floral structure from before to after anthesis indicates an inability for T. balansae to self-pollinate and a requirement for an external vector to effectively transfer pollen from the anthers onto the stigmas of this species. Seed set can be obtained by hand or honeybee manipulation of T. balansae flowers.ConclusionsTrigonella balansae is a self-compatible species, but which requires vectors such as honeybees to bring about pollination.
