Claim 1comparative responsesupports2008Source 1DOIPubMed

Morning and midday inoculations produce higher salicylic acid accumulation, faster pathogenesis-related gene expression, and a more pronounced hypersensitive response than evening or night inoculations.

Quoted textsource-backed
Morning and midday inoculations result in higher salicylic acid accumulation, faster expression of pathogenesis-related genes, and a more pronounced hypersensitive response than inoculations in the evening or at night.
Claim 2functional specificitysupports2008Source 1DOIPubMed

Phytochrome photoperception is important during systemic rather than local resistance induction.

Quoted textsource-backed
Our findings highlight the importance of phytochrome photoperception during systemic rather than local resistance induction.
Claim 3loss of function effectsupports2008Source 1DOIPubMed

Induction of systemic acquired resistance and salicylic-acid-dependent systemic defense reactions is compromised in phyAphyB mutants.

Quoted textsource-backed
Induction of SAR and salicylic-acid-dependent systemic defense reactions, however, are compromised in phyAphyB mutants.
Claim 4mechanistic attributionsupports2008Source 1DOIPubMed

The increased defense capability after day inoculations is attributed to the availability of a prolonged light period during early plant-pathogen interaction rather than to circadian rhythm.

Quoted textsource-backed
Rather than to the plants' circadian rhythm, this increased plant defense capability upon day inoculations is attributable to the availability of a prolonged light period during the early plant-pathogen interaction.
Claim 5pathway involvementsupports2008Source 1DOIPubMed

Phytochrome regulation of systemic acquired resistance involves FLAVIN-DEPENDENT MONOOXYGENASE1.

Quoted textsource-backed
Phytochrome regulation of SAR involves the essential SAR component FLAVIN-DEPENDENT MONOOXYGENASE1.
Claim 6systemic response capacitysupports2008Source 1DOIPubMed

The blue-light receptor mutants cry1cry2 and phot1phot2 are capable of establishing a full systemic acquired resistance response.

Quoted textsource-backed
the blue-light receptor mutants cry1cry2 and phot1phot2 are both capable of establishing a full systemic acquired resistance (SAR) response
Claim 7time of day dependencysupports2008Source 1DOIPubMed

In Arabidopsis challenged with Pseudomonas syringae, plant defense responses and disease resistance depend on the time of day of pathogen contact.

Quoted textsource-backed
Within a fixed light/dark cycle, plant defense responses and disease resistance significantly depend on the time of day when pathogen contact takes place.
