Optical Multicast Routing Under Light Splitter Constraints [PDF]

open access: yes, 2010
During the past few years, we have observed the emergence of new applications that use multicast transmission. For a multicast routing algorithm to be applicable in optical networks, it must route data only to group members, optimize and maintain loop ...

RcaE-Dependent Regulation of Carboxysome Structural Proteins Has a Central Role in Environmental Determination of Carboxysome Morphology and Abundance in Fremyella diplosiphon

open access: yesmSphere, 2018
Carboxysomes are central to the carbon dioxide-concentrating mechanism (CCM) and carbon fixation in cyanobacteria. Although the structure is well understood, roles of environmental cues in the synthesis, positioning, and functional tuning of carboxysomes

The PEAPOD repressor complex in Arabidopsis stomatal development

open access: yesFrontiers in Plant Science
Stomata comprise two guard cells that function as microscopic valves in the plant epidermis, connecting mesophyll interstices to the atmosphere. Stomata regulate gas exchange and evapotranspiration, directly impacting photosynthesis and leaf temperature ...

A Regulatory Mechanism on Pathways: Modulating Roles of MYC2 and BBX21 in the Flavonoid Network

open access: yesPlants
Genes of metabolic pathways are individually or collectively regulated, often via unclear mechanisms. The anthocyanin pathway, well known for its regulation by the MYB/bHLH/WDR (MBW) complex but less well understood in its connections to MYC2, BBX21 ...

Interplay between Light and Plant Hormones in the Control of Arabidopsis Seedling Chlorophyll Biosynthesis

open access: yesFrontiers in Plant Science, 2017
Chlorophyll biosynthesis is one of the most important cellular processes and is essential for plant photosynthesis. After germination under the soil, dark-grown seedlings are etiolated and accumulate the chlorophyll precursor protochlorophyllide (Pchlide)

slim shady is a novel allele of PHYTOCHROME B present in the T‐DNA line SALK_015201

open access: yesPlant Direct, 2021
Auxin is a hormone that is required for hypocotyl elongation during seedling development. In response to auxin, rapid changes in transcript and protein abundance occur in hypocotyls, and some auxin responsive gene expression is linked to hypocotyl growth.

Helstrom Theorem by No-Signaling Condition

open access: yes, 2005
We prove a special case of Helstrom theorem by using no-signaling condition in the special theory of relativity that faster-than-light communication is impossible.Comment: Minor corrections (A reference added, discussion part deleted, typos in ...

Photoswitchable diacylglycerols enable optical control of protein kinase C. [PDF]

open access: yes, 2016
Increased levels of the second messenger lipid diacylglycerol (DAG) induce downstream signaling events including the translocation of C1-domain-containing proteins toward the plasma membrane. Here, we introduce three light-sensitive DAGs, termed PhoDAGs,

CML38 is involved in NO-induced inhibition of hypocotyl elongation in Arabidopsis

open access: yesFrontiers in Plant Science
Calcium ions (Ca2+) are vital in plants, functioning both as structural cellular components and key secondary messengers that regulate growth, development, and stress responses.

The tumor-promoting functions of Ataxia-telangiectasia mutated (ATM) in cancer cells [PDF]

open access: yes, 2015
textAtaxia-telangiectasia mutated (ATM) protein kinase regulates the DNA damage response (DDR) and is associated with cancer suppression by protecting cells from DNA double-strand breaks (DSBs). However, how ATM functions outside of DSB signaling is less
