| Title: Rice leaf inclination2 , a VIN3-like protein , regulates leaf angle through modulating cell division of the collar .
| | Author: Zhao SQ Hu J Guo LB Qian Q Xue HW | | Journal: Cell Res Citation: V : 20 P : 935-47 Year: 2010 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub20644566 Accession (PMID): 20644566 | | Abstract: As an important agronomic trait , inclination of leaves is crucial for crop architecture and grain yields .
To understand the molecular mechanism controlling rice leaf angles , one rice leaf inclination2 ( lc2 , three alleles ) mutant was identified and functionally characterized .
Compared to wild-type plants , lc2 mutants have enlarged leaf angles due to increased cell division in the adaxial epidermis of lamina joint .
The LC2 gene was isolated through positional cloning , and encodes a vernalization insensitive 3-like protein .
Complementary expression of LC2 reversed the enlarged leaf angles of lc2 plants , confirming its role in controlling leaf inclination .
LC2 is mainly expressed in the lamina joint during leaf development , and particularly , is induced by the phytohormones abscisic acid , gibberellic acid , auxin , and brassinosteroids .
LC2 is localized in the nucleus and defects of LC2 result in altered expression of cell division and hormone-responsive genes , indicating an important role of LC2 in regulating leaf inclination and mediating hormone effects .

| Title: [ Effect of culture media on virulence of Hirsutella thompsonii ( Fischer ) ( Deuteromycetes ) to control Brevipalpus phoenicis ( Geijskes ) ( Acari : Tenuipalpidae ) . ] | | Author: Rossi-Zalaf LS Alves SB Vieira SA | | Journal: Neotrop Entomol Citation: V : 37 P : 312-20 Year: 2008 Type: In-Data-Review | | Literature: oryza Field: abstract Doc ID: pub18641903 Accession (PMID): 18641903 | | Abstract: The virulence of Hirsutella thompsonii ( Fischer ) to Brevipalpus phoenicis ( Geijskes ) was evaluated in laboratory , grown on complete and solid culture media ( MC-S ) ; complete and liquid culture media ( MC-L ) ; rice ( APC ) and powdered rice ( APC-SM ) .
Adults were confined to arenas prepared with citrus leaves in acrylic dishes containing water-agar .
Conidial suspensions were prepared at different concentration ( 3 . 2 x 10 ( 5 ) to 1 x 10 ( 7 ) spores/ml ) and applied on mites to establish the table curve-response on fourth day .
For field evaluation , adults were maintained in arenas prepared with fruits which were placed in plants .
In this test , four treatments were tried : H thompsonii cultured on rice ( APC ) at two concentrations ( 20 kg/ha and 10 kg/ha ) , H thompsonii produced by liquid fermentation ( MC-L ) ( 5 L/ha ) and control ( sterile water ) .
Adult survival , number of eggs and nymphs per fruit were observed 10 and 20 days after the fungus application .
The lowest LC25 value calculated was from pathogen produced in MC-S ( 1 . 9 x 10 ( 5 ) conidia/ml ) . The LC25 values calculated to APC and APC-SM did not differ statistically .
The LC25 values to MC-L and MC-S were 1 . 9 x 10 ( 6 ) infective cells/ml and 2 . 2 x 10 ( 5 ) conidia/ml .
In the field , concentration and time to death differed between treatments and control .
The applications resulted in reduction of adult survival and number of eggs .
