Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2014 Seed evolution: parental conflicts in a multi-generational household Pires, Nuno D Abstract: Seeds are multi-generational structures containing a small embryonic plant enclosed in layers of diverse parental origins. The evolution of seeds was a pinnacle in an evolutionary trend towards a progressive retention of embryos and gametes within parental tissue. This strategy, which dates back to the first land plants, allowed an increased protection and nourishing of the developing embryo. Flowering plants took parental control one step further with the evolution of a biparental endosperm that derives from a second parallel fertilization event. The endosperm directly nourishes the developing embryo and allows not only the maternal genes, but also paternal genes, to play an active role during seed development. The appearance of an endosperm set the conditions for the manifestation of conflicts of interest between maternal and paternal genomes over the allocation of resources to the developing embryos. As a consequence, a dynamic balance was established between maternal and paternal gene dosage in the endosperm, and maintaining a correct balance became essential to ensure a correct seed development. This balance was achieved in part by changes in the genetic constitution of the endosperm and through epigenetic mechanisms that allow a differential expression of alleles depending on their parental origin. This review discusses the evolutionary steps that resulted in the appearance of seeds and endosperm, and the epigenetic and genetic mechanisms that allow a harmonious coinhabitance of multiple generations within a single seed.

The national park was F E R N S established in 1968. In 1994, a cooperative agreement with the California Department of Parks and Recreation added Del Norte Coast, Prairie Creek, Athyriaceae – Lady Fern Family and Jedediah Smith Redwoods state parks to form a single administrative Athyrium filix-femina var. cyclosporum • northwestern lady fern unit. Together they comprise about 133,000 acres (540 km2), including 37 miles of coast line. Almost half of the remaining old growth redwood forests Blechnaceae – Deer Fern Family are protected in these four parks.

Mr. O’Connell discussed the 8 importance of considering the western bumble bee. Ms. Flannery discussed the 9 importance of the hard ocean floor substrate and asked how the cable would be secured 10 to the ocean floor to reduce or eliminate scour. The western bumble bee has been 11 evaluated in the Biological Resources section of the main document, and direct and 12 indirect impacts are avoided. The Project Description describes in detail how the cable 13 would be installed on the ocean floor, the importance of the hard bottom substrate, and 14 the need for avoidance. 15 Consultation Outcomes: 16 • The Project was designed to avoid hard bottom substrate, and RTI Infrastructure 17 (RTI) conducted surveys of the ocean floor to ensure that proper routing of the 18 cable would occur. 19 • Ms. Flannery will be copied on all communications with the National Marine 20 Fisheries Service 21 California Department of Fish and Wildlife: On August 7, 2020, ICF held a conference 22 call with Greg O’Connell to discuss a site assessment and survey approach for the 23 western bumble bee.
