LONG-TERM DATA SETS. "Regulation of the saccharide metabolism may provide additional examples of integrating, storing and accessing information on long-term state of the plants' metabolism, including but not limited to the performance of the photosynthetic apparatus." https://lnkd.in/dfsCv77 View in LinkedIn

SO ENDS this first of two weekends contemplating the return to the sea of the seagrasses. Like the whales, these organisms have made this challenging reversal by numerous genetic, biochemical, anatomic, and physiological modifications, rendering them totally different from the creatures that first emerged from the sea to dry land. Their return was not simply a reversal of status, a return to how they were. It was more strenuous — by far — than the twisting of a vertical flatfish face horizontal. View in LinkedIn

COMPLEX DORMANCY. "We are also catching first glimpses of the complex web of hormonal and gene expression regulatory pathways controlling seed dormancy, as well as the intricate interplay of light-dependent signals such as phytochrome modification, circadian rhythms and phytormonones implicated in light-controlled developmental regulation." https://lnkd.in/dfsCv77 View in LinkedIn

NEW CHALLENGES. "Submergence also exposes organisms to the forces of wave action and tidal currents that effects reproductive functions and reduces the availability of carbon dioxide (CO2). Consequently, seagrasses have evolved to propagate via hydrophilous pollination and rely on carbonic acid and bicarbonate instead of CO2." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

VERNALIZATION EPIGENETICS. "The “memory of winter” involved in seasonally dependent acquisition of flowering competence (vernalization) has been traced down to complex epigenetic regulation of the gene encoding a specific transcription factor in Arabidopsis." https://lnkd.in/dfsCv77 View in LinkedIn

ANAEROBIC SEDIMENT. "One factor contributing to these high light requirements is the reducing sediments to which seagrasses are rooted. These sediments challenge seagrass root tissues with anaerobic conditions since marine sediments are often oxygen deficient. When the internal transport of oxygen from shoot to root tissues is not sufficient, seagrasses can be forced to resort to fermentative metabolism." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-11-8 View in LinkedIn

DATA RECALL AND EVALUATION. "Developmental decisions, such as vernalization, flowering induction, photomorphogenesis or breaking of seed dormancy depend on long-term integration and evaluation of light or temperature inputs, sometimes recorded and recalled after a time far exceeding the normal duration of the plant's life cycle." https://lnkd.in/dfsCv77 View in LinkedIn

EXCLUDED CANDIDATES. "Nevertheless, even on the basis of the mere memory criterion we could exclude some phenomena that were promising at the first glance but turned out to be explainable by models not including memory." https://lnkd.in/dfsCv77 View in LinkedIn
