VARIETY OF SUPPRESSIONS. "This variation in timing and nature of suppression argues for the existence of a variety of different underlying mechanisms." https://lnkd.in/gb3zS32 View in LinkedIn

LATE DIVERGENCE. "In a small number of dioecious species such as Actinidia deliciosa and Asparagus officinalis, the developmental divergence occurs so late that male and female flowers are superficially indistinguishable from each other and from perfect flowers." https://lnkd.in/gb3zS32 View in LinkedIn

ABORTION OF ONE SEX. "In most species, however, both sets of sex organs are initiated and the inappropriate set of organs develops to some extent before abortion." https://lnkd.in/gb3zS32 View in LinkedIn

EARLY DIVERGENCE. "In a number of dioecious species, including Mercurialis annua, Cannabis sativa, Spinacia oleracea, and Humulus species, the divergence of the male and female developmental pathways occurs extremely early in floral development and the inappropriate organs are not initiated." https://lnkd.in/gb3zS32 View in LinkedIn

SUPPRESSION TIMING. "Comparison of male and female flowers from the various dioecious species reveals that the timing during flower development of the suppression event is enormously variable between species." https://lnkd.in/gb3zS32 View in LinkedIn

SUPPRESSION OF ONE SEX. "It is evident that the floral dichotomy shown by dioecious plant species results from modification during development of a perfect flower by suppression of one or other organ sets." https://lnkd.in/gb3zS32 View in LinkedIn

EARLY DISEASE FOCUS. “Since the late 1800s, the discovery of new viruses was a gradual process. Viruses were described one by one using a suite of techniques such as (electron) microscopy and viral culture. Investigators were usually interested in a disease state within an organism, and expeditions in viral ecology were rare.” https://lnkd.in/g35Hmrp View in LinkedIn

DARK AGES. “Our best guess is that there are 10 million living species, more or less, excluding the single-celled bacteria and Archaea. Of these, fewer than two million are known to science. And of documented species, most are known by little more than a few diagnostic features and a name.” Characteristically, and sadly, this perspective omits to even mention of the most numerous and diverse group of creatures on Planet Earth, namely, viruses. https://lnkd.in/giV3WBx View in LinkedIn

130 HUMAN DISEASE VIRUS CURATED DATABASE, (Swiss Institute of Bioinformatics). 130 out of millions of species are pathogenic. Here is the updated list of all the bad guys. https://lnkd.in/gCk2PYC View in LinkedIn

THE FLAMMARION ENGRAVING of 1888 shows a pilgrim peering under the mantle of the heavens to learn of the hidden workings of the world. Little has changed since this date. Despite all our self-congratulatory efforts, even our descriptive knowledge to simple catalogue and enumerate our world is only less than 1% of the total biological diversity, when viruses are figured into the equation. A Martian arriving at planet earth might indeed be surprised by this state of affairs. https://lnkd.in/gmMe6gB View in LinkedIn
