- 2 June 2005
This work isolated and characterized a novel gene controlling the initiation of adventitious root primordia in rice, and suggests that ARL1 is an auxin-responsive factor involved in auxIn-mediated cell dedifferentiation, and that it promotes the initial cell division in the pericycle cells adjacent to the peripheral vascular cylinder in the stem.

Molecular dissection of the pathogen-inducible 3-deoxyanthocyanidin biosynthesis pathway in sorghum.
It is revealed that 3-deoxyanthocyanidin accumulation and SbDFR3 expression were induced by methyl jasmonate treatment in sorghum roots but the stimulation effects were antagonized by salicylic acid. Expand
Cytochrome P450 93G1 Is a Flavone Synthase II That Channels Flavanones to the Biosynthesis of Tricin O-Linked Conjugates in Rice1[C][W]
It is established that CYP93G1 is a key branch point enzyme channeling flavanones to the biosynthesis of tricin O-linked conjugates in rice and functional diversification of F2H and FNSII in the cytochrome P450 CYP 93G subfamily may represent a lineage-specific event leading to the prevalent cooccurrence of flavone C- and O- linked derivatives in grasses today.

Completion of Tricin Biosynthesis Pathway in Rice: Cytochrome P450 75B4 Is a Unique Chrysoeriol 5′-Hydroxylase1
It is reported here that CYP75B4 a unique flavonoid B-ring hydroxylase indispensable for tricin formation in rice and recruitment of chrysoeriol-specific 5′-hydroxyl enzyme activity by an ancestral CYP 75B sequence may represent a key event leading to the prevalence oftricin-derived metabolites in grasses and other monocots today.

Isolation and expression analysis of defense-related genes in sorghum–Colletotrichum sublineolum interaction
A cDNA library enriched for defense response mRNAs was constructed by suppression subtractive hybridization of inoculated mesocotyl tissues of a resistant cultivar and provided an efficient resource for sorghum defense-related gene discovery that may further enhance the investigation of molecular mechanisms of defense responses in Sorghum toward fungal pathogens.

OsNOA1/RIF1 is a functional homolog of AtNOA1/RIF1: implication for a highly conserved plant cGTPase essential for chloroplast function.
Significant indications are provided that a highly conserved nuclear-encoded cGTPase of likely prokaryotic origin is essential for proper chloroplast ribosome assembly and/or translation in plants. Expand
Differential Regulation of Protochlorophyllide Oxidoreductase Abundances by VIRESCENT 5A (OsV5A) and VIRESCENT 5B (OsV5B) in Rice Seedlings.
Young Leaf Chlorosis 2 encodes the stroma-localized heme oxygenase 2 which is required for normal tetrapyrrole biosynthesis in rice
Rice heme oxygenase 2 (OsHO2) mutants are chlorophyll deficient with distinct tetrapyrrole metabolite and transcript profiles, suggesting a potential regulatory role of the stromal-localized OsHO2 in tetrapirrole biosynthesis. Expand
Recruitment of specific flavonoid B-ring hydroxylases for two independent biosynthesis pathways of flavone-derived metabolites in grasses.
In rice (Oryza sativa), OsF2H and OsFNSII direct flavanones to independent pathways that form soluble flavone C-glycosides and tricin-type metabolites (both soluble and lignin-bound), respectively.… Expand
Functional identification and regulatory analysis of Δ6-fatty acid desaturase from the oleaginous fungus Mucor sp. EIM-10
- X. Jiang, Hongjiao Liu, Yongchao Niu, F. Qi, Mingliang Zhang, Jianzhong Huang
- Biotechnology Letters
The native promoter of Md6 from Mucor is the strongest promoter for Δ 6-desaturase reported so far and the sequence between −919 to −784 bp is an enhancer for Δ6- Desaturase activity. Expand
