Functional and morphological evolution in gymnosperms: A portrait of implicated gene families
The gymnosperms , also known as Acrogymnospermae , are a group of seed-producing plants that includes conifers , cycads , Ginkgo , and gnetophytes. The name is based on the unenclosed condition of their seeds called ovules in their unfertilized state. The non-encased condition of their seeds contrasts with the seeds and ovules of flowering plants angiosperms , which are enclosed within an ovary. Gymnosperm seeds develop either on the surface of scales or leaves, which are often modified to form cones , or solitary as in yew , Torreya , Ginkgo. The gymnosperms and angiosperms together compose the spermatophytes or seed plants. The gymnosperms are divided into six phyla. Organisms that belong to the Cycadophyta, Ginkgophyta, Gnetophyta, and Pinophyta also known as Coniferophyta phyla are still in existence while those in the Pteridospermales and Cordaitales phyla are now extinct.
Angiosperm vs Gymnosperm: What are the Similarities & Differences?
Life as we know it would not exist without plants to convert sunlight and inorganic compounds into food energy. In Kingdom Plantae, plant species are classified according to their method of reproduction. One group is the "seed plants," which can be divided into two subgroups called angiosperms and gymnosperms. Angiosperm derives from the Greek words for "vessel" and "seed. They reproduce by making seeds that are enclosed in an ovary. Gymnosperm derives from the Greek words for "naked seeds. They are cone-bearing and reproduce by making naked seeds on cone scales or leaves.

In this paper, we aim to understand how genes and gene families have contributed to the major functional and morphological differences in gymnosperms, and how this information can be used for applied breeding and biotechnology. In addition, we have analyzed the angiosperm versus gymnosperm evolution of the pleiotropic drug resistance PDR gene family with a wide range of functionalities in plants' interaction with their environment including defense mechanisms. Some of the genes reviewed here are newly studied members of gene families that hold potential for biotechnological applications related to commercial and pharmacological value. Some members of conifer gene families can also be exploited for their potential in phytoremediation applications.
