AERENCHYMA FORMATION IN MAIZE PLANTS UNDER PHOSPHORUS DEFICIENCY

open access: yesRevista Brasileira de Milho e Sorgo, 2006
The objective of this work was to verify, under phosphorus stress (P), possible alterations to the root anatomy of maize inbred line A188 and its transgenic version having the genetic construction AtPT2::GUS. AtPT2::GUS plants were used as a positive control to validate the P stress, once this promoter directs GUS reporter gene expression only to the ...

ELM‐Wet: Inclusion of a Wet‐Landunit With Sub‐Grid Representation of Eco‐Hydrological Patches and Hydrological Forcing Improves Methane Emission Estimations in the E3SM Land Model (ELM)

open access: yesJournal of Advances in Modeling Earth Systems
Wetlands are the largest emitters of biogenic methane (CH4) and represent the highest source of uncertainty in global CH4 budgets. Here, we aim to improve the realism of wetland representation in the U.S.
