The following points highlight the top nine theories about ancestors of angiosperms. Advocates of the Glossopteris-ohgin theory propose the glossopteris vegetative leaf to be homologous with the angiosperms carpel, and the megasporophyll with the outer integument of an angiosperm seed, based on some peculiar specimens with abaxially borne seeds. ARAPOT (www.araport.org) is also an important Arabidopsis genome database that provides updated genome sequence (currently V11), various gene information and protein interaction networks.

The Gnetales resemble angiosperms in many respects: 1.

Toronto agreement was proposed in 2009 (Toronto International Data Release Workshop Authors, 2009), aimed to share the scientific data such as the genome sequences before the publication. This incongruity suggests that knowledge of pollination arrangements of Mesozoic seed plants is far from complete; some plants have been described with stigmatic surfaces, and investigation of their morphological intermediate position needs much fuller attention. 7.

Compared to other green lineage clades, the angiosperms play the most important roles in our human life. Three problems are constantly encountered for species-specific genome databases. Although accessing some databases is not convenient, a few species have more than one genome database. Since 2001, various angiosperm genome databases have been developed synchronizing with the progress of sequencing projects of angiosperm genomes. Doyle,J.

We reviewed and compared the pros and cons on the data, tools, special highlights from three types of genome databases that are mostly used. Data should integrate the reference but not draft genome, CDS, protein, GFF, GO annotation, and the sequencing quality report. Bennettitalean Theory: According to Saporta and Marion (1885), and Arber and Parkin (1907), the Bennettitales of gymnosperm is the possible ancestor of angiosperms. However, there are two serious objections to the theory of Pteridospermi ancestry of angiosperms, which include: a. Some of the angiosperms like Trochodendron, Tetracentron and others, which lack vessels, have a structurally more primitive secondary xylem than conifers as well as amentifers.

According to this theory most of the dicotyledons were thought to have ovules enclosed in foliar carpels while the Monochlamydeae and most of the monocotyledons were considered to have mega sporangia protected by sterile organs.

The Bennettitalean theory was first proposed by Saporta and Marion (1885), followed by Arber and Parkin according to which, Bennettitales have been proposed as possible ancestors of angiosperms, on the basis of the resemblance in structure between the strobili of the Mesozoic genus Cycadeoidea and the flower of Magnolia. 80, 528580 (1993).

Van de Peer Y., Mizrachi E., Marchal K.
