Evolutionary flexibility in flooding response circuitry in angiosperms.

Summary of "Evolutionary flexibility in flooding response circuitry in angiosperms."

Flooding due to extreme weather threatens crops and ecosystems. To understand variation in gene regulatory networks activated by submergence, we conducted a high-resolution analysis of chromatin accessibility and gene expression at three scales of transcript control in four angiosperms, ranging from a dryland-adapted wild species to a wetland crop. The data define a cohort of conserved submergence-activated genes with signatures of overlapping cis regulation by four transcription factor families. Syntenic genes are more highly expressed than nonsyntenic genes, yet both can have the cis motifs and chromatin accessibility associated with submergence up-regulation. Whereas the flexible circuitry spans the eudicot-monocot divide, the frequency of specific cis motifs, extent of chromatin accessibility, and degree of submergence activation are more prevalent in the wetland crop and may have adaptive importance.

Increasing flooding tolerance in rice: combining tolerance of submergence and of stagnant flooding.

Rice ecosystems in the tropical coastal areas are subject to two types of flooding stress: transient complete submergence and long-term water stagnation (stagnant flooding). Here, we aimed to dissect ...

Phosphorus Release from Unamended and Gypsum- or Biochar-Amended Soils under Simulated Snowmelt and Summer Flooding Conditions.

Prolonged flooding changes the oxidation-reduction status of soils, often enhancing P release to overlying floodwater. We studied P release from unamended, gypsum-amended, and biochar-amended soils un...

Medical and Biotech [MESH] Definitions

Members of the group of vascular plants which bear flowers. They are differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida). Angiosperms represent approximately 80% of all known living plants.

Functional proteins that do not have unique, stable, folded, three-dimensional native structures or that possess non-ordered regions under physiological conditions. They are characterized by extraordinary structural flexibility and plasticity, which enable them to adopt different conformations in response to different stimuli or different interactions.

An order of monocotyledons (superorder Lilianae) in the class Magnoliopsida (Angiosperms).

One of many different processes which occur in ANGIOSPERMS by which genetic diversity is maintained while INBREEDING is prevented.

Woody, usually tall, perennial higher plants (Angiosperms, Gymnosperms, and some Pterophyta) having usually a main stem and numerous branches.
