  • depletion
  • The depletion of a usable nitrogen source induces sexually incompetent gametes, named pregametes in the dark [ 11 ]. (mdpi.com)
  • In the unicellular algae Chlamydomonas reinhardtii , the plus and minus mating types are controlled by a complex locus, MT , where the dominant MID gene in the MT − locus has been shown to be necessary for expression of minus -specific gamete-specific genes in response to nitrogen depletion.

  • fertilizers
  • Burley tobacco required six-fold more nitrogen fertilizers than flue-cured tobacco, but both tobaccos had a similar leaf biomass. (mdpi.com)
  • Indeed, these two plants, which are with rice the base for food and feed in the world requires significant inputs of N fertilizers (nitrates in particular) for optimum performance. (plannet-rcn.org)
  • The improvement of NUE is a major issue, considering both the growing demand for agricultural products of the world population, the rising cost of fossil fuels needed to produce N fertilizers and water pollution caused by the application in excess of nitrates to fertilize cultivated soils.

  • ribosomal
  • Archaea were first classified as a separate group of prokaryotes in 1977 by Carl Woese and George E. Fox in phylogenetic trees based on the sequences of ribosomal RNA (rRNA) genes. (wikipedia.org)
  • This new appreciation of the importance and ubiquity of archaea came from using polymerase chain reaction (PCR) to detect prokaryotes from environmental samples (such as water or soil) by multiplying their ribosomal genes. (wikipedia.org)
  • species
  • The largest part of the Earth's microbial biomass is stored in cold environments, which represent almost untapped reservoirs of novel species, processes, and genes. (pubmedcentralcanada.ca)
  • Expression
  • Out of 4,390 unique genes, a total of 188 had a twofold or more up- (84) or down-regulated (104) expression level in E2Fa-DPa transgenic plants compared to wild-type lines. (biologists.org)
  • We identify GlnR as a regulator involved in the nitrogen response, controlling the expression of at least 33 genes in response to nitrogen limitation. (imperial.ac.uk)
  • We report studies on MID expression patterns during gametogenesis and on a second gene unique to the MT − locus, MTD1 . (genetics.org)
