Shedding light on photoperiodism [PDF]
Proceedings of the National Academy of Sciences, 2010 In mammals, photoreception is restricted to the eye. By contrast, nonmammalian vertebrates possess photoreceptors in a wide array of extraocular tissues, including the pineal complex and brain (1). The identity of the deep brain photoreceptors has remained elusive.

Advanced Science, EarlyView.A schematic illustration of the cyanobacteria‐based biohybrid platform for photodynamic cancer therapy enhanced PDT. The platform continuously outputs O2 (to alleviate tumor hypoxia) and 1O2 (for tumor treatment), achieving improved photodynamic immunotherapy. Abstract The interdisciplinary development of synthetic biology and material sciences propels

Identification of a homolog of Arabidopsis DSP4 (SEX4) in chestnut: its induction and accumulation in stem amyloplasts during winter or in response to the cold_ [PDF]
, 2011 Oligosaccharide synthesis is an important cryoprotection strategy used by woody plants during winter dormancy. At the onset of autumn, starch stored in the stem and buds is broken down in response to the shorter days and lower temperatures resulting in ...

Advanced Energy and Sustainability Research, EarlyView.Using CO2‐rich polluting gases in greenhouse plant cultivation has proven to be a promising technique for stimulating plants while reducing emissions to the atmosphere. The use of an experimental biofilter proves to be effective in retaining most of the toxic particles. The alteration of physiological and metabolic parameters shows an adaptation of the

PHOTOPERIODIC RESPONSE OF LESPEDEZA [PDF]
Plant Physiology, 1952 Several attempts have been made to establish various leguminous plants as forage and cover crops on pasture land in Hawaii. Korean Lespedeza (Lespedeza stipulacea Maxim) and the common Lespedeza (L. striata Thunb. H and A) were among those tried. These two species are widely grown throughout the central and southern parts of the United States, where ...

Transcriptomic and proteomic analyses of seasonal photoperiodism in the pea aphid
BMC Genomics, 2009 BackgroundAphid adaptation to harsh winter conditions is illustrated by an alternation of their reproductive mode. Aphids detect photoperiod shortening by sensing the length of the night and switch from viviparous parthenogenesis in spring and summer, to

High irradiance responses involving photoreversible multiple photoreceptors as related to photoperiodic induction of cell division in Euglena [PDF]
, 2007 application/pdfLittle is known about the photoreceptors involved in the photoperiodism of unicellular organisms, which we elucidated by deriving their action spectra. The flagellated alga Euglena gracilis exhibits photoperiodism, with a long-day response

Dawn and photoperiod sensing by phytochrome A [PDF]
Proceedings of the National Academy of Sciences, 2018 AbstractIn plants, light receptors play a pivotal role in photoperiod sensing, enabling them to track seasonal progression. Photoperiod sensing arises from an interaction between the plant’s endogenous circadian oscillator and external light cues. Here, we characterise the role of phytochrome A (phyA) in photoperiod sensing.

Trophobiosis Theory: A Pest Starves on a Healthy Plant [PDF]
, 2007 Pests shun healthy plants. Pesticides weaken plants. Weakened plants open the door to pests and disease. Hence pesticides precipitate pest attack and disease susceptibility, and thus they induce a cycle of further pesticide use.
