Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Klebsiella sp. strain B7 enhances alkaline tolerance by secreting pyruvic acid to accelerate L‐malic acid accumulation in soybean

open access: yesJournal of Integrative Plant Biology, EarlyView.
Klebsiella sp. strain B7 acts as a positive regulator in alkaline stress responses in soybean. By activating pyruvic acid metabolism and L‐malic acid biosynthesis pathways, B7 significantly increases alkaline tolerance and yield in soybean. ABSTRACT Alkaline stress is a major constraint on crop growth and development and negatively impacts soybean ...
