Linked Claims

Claim 1causal chainsupports2017Source 1DOI PubMed

Reduced carbon source under shading is proposed to cause lower lignin and cellulose accumulation in culm, contributing to poor stem strength and higher lodging risk.

Quoted textsource-backed

The decrease of carbon source under shading condition is the cause for the lower lignin and cellulose accumulation in culm.

Shading decreases the stem mechanical strength of japonica rice

Claim 3gene expression changesupports2017Source 1DOI PubMed

Shading significantly decreases expression of lignin and cellulose biosynthesis genes including OsPAL, OsCOMT, OsCCoAOMT, OsCCR, OsCAD2, OsCesA1, OsCesA3, and OsCesA8.

Quoted textsource-backed

under shading condition, gene expression involved in secondary cell wall synthesis, OsPAL, OsCOMT, OsCCoAOMT, OsCCR, and OsCAD2, and primary cell wall synthesis, OsCesA1, OsCesA3, and OsCesA8 were decreased significantly

Claim 4mechanistic explanationsupports2017Source 1DOI PubMed

Shading decreases non-structural carbohydrate, sucrose, lignin, and cellulose accumulation in rice culms.

Quoted textsource-backed

Compared with control, cell wall components including non-structural carbohydrate, sucrose, cellulose, and lignin reduced quite higher.
