GASA genes in maize, ZmGASA family

Extracted Explainers

What the tool is doing

This paper defines and characterizes the maize GASA gene family at the genome, structure, promoter, evolutionary, and expression levels. It frames the family as a set of low-phosphorus-responsive candidate genes in maize.

Source 1DOIPubMed

Resources required

Using this family-level result requires maize genome annotation plus transcriptomic and qRT-PCR data or similar expression assays.

Source 1DOIPubMed

What problem it solves

It solves the basic cataloging problem of which GASA genes are present in maize and which appear responsive to low-phosphorus stress.

Source 1DOIPubMed

What it does not solve

The abstract does not show direct mechanistic or causal validation of how specific ZmGASA genes control low-phosphorus tolerance.

Source 1DOIPubMed

Alternatives

The source mentions comparative synteny with sugarcane GASA genes and situates the work within broader plant GASA family studies.

Linked Claims

Claim 1comparative evolutionsupports2026Source 1DOIPubMed

Comparative synteny indicated close evolutionary relationships between maize and sugarcane GASA genes, implying divergence from a common ancestor.

Claim 2expression responsesupports2026Source 1DOIPubMed

Maize GASA genes show tissue-specific and low-phosphorus-stress-responsive expression patterns based on transcriptomic and qRT-PCR analyses.

Claim 3family identificationsupports2026Source 1DOIPubMed

The maize genome contains 13 GASA genes distributed across six chromosomes.

Claim 4phylogenetic classificationsupports2026Source 1DOIPubMed

Comprehensive analyses classified maize GASA genes into three conserved clades.

Claim 5promoter inferencesupports2026Source 1DOIPubMed

Promoter cis-element analysis suggested that maize GASA genes are associated with developmental regulation, phytohormone responses, abiotic stress adaptation, and light signaling.
