Three new species of the genus Parorthocladius Thienemann, P. lazovskiensis sp. nov., P. plolabius sp. nov., and P. tyurkini sp. nov. from the Russian Far East are described and figured. Descriptions of pupae and larvae of one indeterminate species, Parorthocladius sp. 1, are also presented. Keys to determination of adult males, pupae and fourth instar larvae of Far-Eastern species Parorthoclad...

The red light inhibition of growth of the intact pea (Pisum sativum L. cv. Alaska) third internode was correlated with an increase in the content of cell wall-bound hydroxyproline. These changes were detected 3 hours after irradiation, and possibly at 1 hour. Far red light reversed the effects of red light. The iron chelator alpha,alpha'-dipyridyl reversed the red light effects on both growth a...

The association between demographic history, genealogy and geographical distribution of mitochondrial DNA cytochrome b haplotypes was studied in the wood lemming (Myopus schisticolor), a species that is closely associated with the boreal forest of the Eurasian taiga zone from Scandinavia to the Pacific coast. Except for a major phylogeographic discontinuity (0.9% nucleotide divergence) in south...

Continuous irradiation of Mesembryanthemum crystallinum plants with light of equal amounts of photosynthetically active radiation, but widely different red:far red ratios was used to intervene in phytochrome-mediated signal transduction pathways in the presence and absence of salt stress. Light with a low ratio of red:far red (in contrast to light with a high ratio of red:far red), caused induc...

Three new species of the subterranean amphipod of the genus Pseudocrangonyx: P. tiunovi sp. nov., P. holsingeri sp. nov., P. sympatricus sp. nov. and male specimen for P. kseniae Sidorov, 2012 from the South Primory, Far East of Russia are described. The species were found in springs and related groundwater habitats of several river systems belonging to the Japan Sea basin. Phylogenetic analysi...

New records of water mites of the family Torrenticolidae Piersig, 1902 (Acari: Hydrachnidia) from streams in South Korea and the Russian Far East are presented. Detailed descriptions or redescrptions are provided for eight species of the genera Torrenticola Piersig, 1896 and Monatractides K. Viets 1926. Two species are described as new to science: Torrenticola kimichungi sp. n. and Monatractide...

A systematic review of the genus Abiskomyia Edwards, 1937 is presented based on materials from the Russian Far East and bordering territories. Three new species: A. korbokhon sp. nov., A. levanidovi sp. nov., A. rivalis sp. nov. and one subspecies A. virgo orientalis subsp. nov. are described and figured. Emended generic diagnoses and keys to determination of adult males, pupae and fourth insta...

The reducing agents, potassium ferrocyanide, beta-mercaptoethylamine, cysteine, reduced DPN, ferrous sulfate, methyl viologen and ascorbic acid caused the expansion in darkness of disks of primary leaf tissue cut from dark-grown bean plants. The reducing agents interacted synergistically with low irradiances of red radiation and additively with high irradiance of red light. Exposure of disks tr...

To identify specific mutants for components of phytochrome A (phyA) signaling in Arabidopsis, we established a light program consisting of multiple treatments with alternating red and far-red light. In wild-type seedlings, irradiation with multiple red light pulses can reduce the amount of phyA, which in turn decreases the high-irradiance responses (HIRs) mediated by the subsequent treatments w...
