Linked Claims

Claim 1comparative mechanistic summarysupports2003Source 1DOI PubMed

Atrazine-resistant and susceptible horseweed biotypes do not differ significantly in carbon dioxide assimilation rate.

Claim 2comparative mechanistic summarysupports2003Source 1DOI PubMed

Atrazine-resistant horseweed chloroplast Hill reaction shows different temperature dependence from susceptible horseweed.

Claim 3comparative mechanistic summarysupports2003Source 1DOI PubMed

Atrazine-resistant horseweed thylakoid membranes contain less polar lipid and more unsaturated fatty acids than susceptible horseweed.

Claim 4photosynthetic limitation summarysupports2003Source 1DOI PubMed

Atrazine-resistant horseweed has reduced xanthophyll-cycle activity, limited non-photochemical and photochemical quenching capacity, and increased photosensitivity and photoinhibition susceptibility.

Claim 5stress response summarysupports2003Source 1DOI PubMed

Atrazine-resistant horseweed shows better adaptation at low temperature but enhanced susceptibility to high-temperature stress.
