Claim 1mechanism exclusionsupports2003Source 1DOI PubMed

Paraquat resistance in Hungarian horseweed is not explained by elevated antioxidant enzyme level or activity.

Claim 2mechanism exclusionsupports2003Source 1DOI PubMed

Polyamines are excluded as the resistance mechanism for paraquat resistance in Hungarian horseweed.

Claim 3proposed mechanismsupports2003Source 1DOI PubMed

A paraquat-inducible, nuclear-coded protein is proposed to contribute to paraquat resistance by carrying paraquat to the vacuole.

Claim 4resistance magnitude summarysupports2003Source 1DOI PubMed

Hungarian horseweed exhibits a paraquat resistance factor of 450.

Claim 5stress response interpretationsupports2003Source 1DOI PubMed

Higher putrescine and total polyamine content in paraquat-treated resistant leaves is interpreted as a general stress response rather than a symptom of paraquat resistance.
