MUTATED CLOCK GENES. “To further determine genetic alterations of clock genes in human cancer, we analyzed non-silent mutations of clock genes across cancer types. We observed that mutation frequency is relatively low for core clock genes, with fewer than five mutations in the majority of samples (Figure 3B). However, mutations of core clock genes were associated with patients' overall survival.” https://lnkd.in/dT2NKaY View in LinkedIn

CONFUSING. "Aquatic plants are notoriously difficult to study systematically due to convergent evolution and reductionary processes that result in confusing arrays of morphological features.” https://lnkd.in/dCDji-W View in LinkedIn

ALGAL JUMP. "Algae dominated the oceans of the precambrian time over 700 million years ago. Between 500 and 400 million years ago, some algae made the transition to land, becoming plants by developing a series of adaptations to help them survive out of the water." https://lnkd.in/d6dpu-q View in LinkedIn

CANDIDATE ALGAE. "Fossil and biochemical evidence indicates plants are descended from multicellular green algae. Various green algal groups have been proposed for this ancestral type, with the Charophytes often being prominently mentioned. Cladistic studies support the inclusion of the Charophytes (including the taxonomic order Coleochaetales) as sister taxa to the land plants." https://lnkd.in/d6dpu-q View in LinkedIn

ALGAE ANCESTORS. "Land plants, also called embryophytes, descended from freshwater algae about 480 Ma. Most of the major phylogenetic groups of land plants now have at least one high-quality draft or reference genome sequence." https://lnkd.in/dWxi2vR View in LinkedIn

EARLY PLANT SEEDS. "However, do we generally appreciate the evolution of this adaptation, much less the diverse effects it has had on terrestrial ecosystems and, indeed, our own culture? No. We take it for granted, even though land plants evolved the seed millions of years before the first amniote is recorded in the fossil record." https://academic.oup.com/bioscience/article/65/6/626/304981/Seeds-and-Fruits-Underwriting-the-Diversity-of View in LinkedIn

PLANT TRANSITION TO DRY LAND. "Plants faced precisely the same problem: that of the pteridophytic life cycle with its free-living gametophytes and swimming sperm in need of freestanding water, being dragged from their supportive environment by the increasingly complex sporophytic adaptations to life on land." https://lnkd.in/d8znE3J View in LinkedIn

FRAGMENT FROM NATURE explores the ancient transition of plants from the water to dry land, and then those that returned to water. Those plants that re-adapted to salt water are the focus of this fragment. These transitions involved considerable changes in metabolism, in particular respiration, which involved biochemical ingenuity, and involved reproductive challenges, These changes opened up new habitats, thus expanding their territorial reach, and ultimately led to the remarkable success of plants.
