Partition of biomass and nitrogen in a potato crop under three nitrogen fertilization treatments
(Universidad Central del Ecuador, 2020)
Nitrogen limitation in arid-subhumid ecosystems: A meta-analysis of fertilization studies
(Academic Press Ltd - Elsevier Science Ltd, 2011-08)
Evidence supporting water limitation in arid-semiarid ecosystems includes strong correlations between aboveground net primary production (ANPP) and annual precipitation as well as results from experimental water additions. ...
The auxin-resistant dgt tomato mutant grows less than the wild type but is less sensitive to ammonium toxicity and nitrogen deficiency
(2020-09-01)
The low-auxin-sensitivity tomato mutant, dgt, despite displaying reduced plant growth, has been linked to greater resistance to N deficiency. This led us to test the role of auxin resistance of dgt in NH4+ toxicity and N ...
Water and nitrogen supply effects on four desert shrubs with potential use for rehabilitation activities
(Springer, 2018-07)
Desert evergreen shrubs, which are adapted to low-fertility ecosystems, generally exhibit limited responses to increased nutrient availability and tend to absorb and store nutrients rather than synthesize new tissues. The ...
The role of heterocytes in the physiology and ecology of bloom-forming harmful cyanobacteria
(Elsevier Science, 2016-12)
Dolichospermum flos-aquae and Cylindrospermopsis raciborskii are two cyanobacteria species which cause harmful blooms around the world. Both these species share the capacity to fix atmospheric nitrogen in heterocytes (cell ...
The effect of nitrogen enrichment on C1-cycling microorganisms and methane flux in salt marsh sediments
(Frontiers, 2012-03)
Methane (CH4) flux from ecosystems is driven by C1-cycling microorganisms – the methanogens and the methylotrophs. Little is understood about what regulates these communities, complicating predictions about how global ...
