Diverse biological effects of glycosyltransferase genes from Tartary buckwheat [PDF]
, 2019 Background: Tartary buckwheat (Fagopyrum tataricum) is an edible cereal crop whose sprouts have been marketed and commercialized for their higher levels of anti-oxidants, including rutin and anthocyanin. UDP-glucose flavonoid glycosyltransferases (UFGTs)

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization
FEBS Letters, EarlyView.CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Bothalia: African Biodiversity & Conservation, 2015 Background: Collections of a tall species of Aristea from the southern coastal mountains of South Africa, with hairless, reddish brown bracts, have been variously identified as Aristea bakeri Klatt or Aristea capitata (L.) Ker Gawl., but do not accord ...

Growth Hormones and Development of Plants [PDF]
Nature, 1936 LATELY great attention has been paid to vernalization of various agricultural plants. Vernalization essentially consists in retarding the germination of seeds by means of insufficient soaking, low temperature, etc. When afterwards the seeds are subjected to normal conditions, further development of the plants proceeds at a greater rate, flowering and ...

The growth of plant embryos in vitro. Preliminary experiments on the role of accessory substances [PDF]
, 1937 The aseptic culture of plant embryos isolated from the seed dates back to the work of Brown and Morris,(1) Hannig(2) and Dietrich.(3) More recent contributions to our knowledge concerning the culture in vitro of excised embryos have been made by Tukey,(4)

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
