| Copia group sequences have been found in diverse species, including single-cell algae, bryophytes, gymnosperms, and angiosperms. |
| Among the plant branches, there were several supported groupings representing only gymnosperms or conifers. |
| A characteristic feature of gymnosperms is polyembryony manifested in the formation of more than one embryo in immature seed. |
| The known flora consists of 41 ferns and fern allies, 3 gymnosperms, 291 monocots, and 516 dicots. |
| These data suggest that the enzyme is well conserved in plants and could play similar physiological roles in angiosperms and gymnosperms. |
| Simple trichomes are present on aerial surfaces of most angiosperms and on some gymnosperms and bryophytes. |
