| Title: Branching in rice .
| | Author: Wang Y Li J | | Journal: Curr Opin Plant Biol Citation: V : 14 P : 94-9 Year: 2011 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub21144796 Accession (PMID): 21144796 | | Abstract: Rice branching , including the formation of tillers and panicle branches , has been well investigated over the past several years because of its agronomic importance .
A major breakthrough in elucidating rice tillering in the recent years was the discovery of strigolactones , a specific group of terpenoid lactones that can inhibit axillary bud outgrowth .
Since that discovery , new tillering mutants , that is , dwarf 27 ( d27 ) or dwarf14 ( d14 , also reported as d88 or htd2 ) , have been identified with reduced strigolactone levels or strigolactone response .
DWARF27 ( D27 ) and DWARF14 ( D14 ) probably act on strigolactone biosynthesis and signal transduction , respectively .
Additionally , several genes controlling panicle branches have been identified recently .
DEP1 and IPA1/WFP are essential dominant/semidominant regulators that determine rice panicle branches and thus affect the grain yields .
More importantly , dep1 and ipa1 alleles have been shown to be applicable for the improvement of rice grain yields in molecular breeding .

| Title: Can heterotrimeric G proteins help to feed the world?
| | Author: Botella JR | | Journal: Trends Plant Sci Citation: V : P : Year: 2012 Type: Publisher | | Literature: oryza Field: abstract Doc ID: pub22748359 Accession (PMID): 22748359 | | Abstract: Recently , two important yield quantitative trait loci ( QTLs ) , GS3 and DEP1 , have been cloned in rice ( Oryza sativa ) .
Although their relationship has not been established in the rice literature , a recent report identified them as heterotrimeric G protein gamma subunits .
This identification has profound consequences for our current understanding of both QTLs and the plant G protein signaling network and this opinion article discusses how manipulation of G protein signaling may lead to yield improvements in rice and other crop species .
Finally , a mechanistic model to explain the seemingly conflicting phenotypes produced by different GS3 and DEP1 alleles is proposed .

| Title: Natural variation at the DEP1 locus enhances grain yield in rice .
| | Author: Huang X Qian Q Liu Z Sun H He S Luo D Xia G Chu C Li J Fu X | | Journal: Nat Genet Citation: V : 41 P : 494-7 Year: 2009 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub19305410 Accession (PMID): 19305410 | | Abstract: Grain yield is controlled by quantitative trait loci ( QTLs ) derived from natural variations in many crop plants .
Here we report the molecular characterization of a major rice grain yield QTL that acts through the determination of panicle architecture .
The dominant allele at the DEP1 locus is a gain-of-function mutation causing truncation of a phosphatidylethanolamine-binding protein-like domain protein .
The effect of this allele is to enhance meristematic activity , resulting in a reduced length of the inflorescence internode , an increased number of grains per panicle and a consequent increase in grain yield .
This allele is common to many Chinese high-yielding rice varieties and likely represents a relatively recent introduction into the cultivated rice gene pool .
We also show that a functionally equivalent allele is present in the temperate cereals and seems to have arisen before the divergence of the wheat and barley lineages .

| Title: The contribution of intersubspecific hybridization to the breeding of super-high-yielding japonica rice in northeast China .
| | Author: Sun J Liu D Wang JY Ma DR Tang L Gao H Xu ZJ Chen WF | | Journal: Theor Appl Genet Citation: V : P : Year: 2012 Type: Publisher | | Literature: oryza Field: abstract Doc ID: pub22660631 Accession (PMID): 22660631 | | Abstract: Hybridization between indica and japonica rice combined with utilization of ideal plant type has led to the development of high-yielding japonica rice in northern China .
However , the contribution at the genomic level of intersubspecific hybridization to the increased yield of northern Chinese japonica rice is uncertain .
In this study , we analyzed the genomic pedigree of descendants of hybridization between indica and japonica rice grown in northeastern China between 1963 and 2008 .
Simple sequence repeat markers indicated that since 1990 the genetic diversity among northern japonica cultivars was enriched .
Genome-wide analysis with subspecies-specific indel and intron length polymorphism markers showed indica-allele frequencies were significantly increased in cultivars bred after 1990 , and were significantly positively correlated with spikelet number per panicle and significantly negatively correlated with panicle number per plant .
Among eight genes controlling agronomic traits , GN1a and GS3 were partially fixed in the genome of northern japonica cultivars .
In contrast , Waxy and qSH1 were eliminated , whereas DEP1 and qSW5 were retained .
Indica germplasm is an important contributor to the increased yield of northern japonica rice .
Breeding for high yield and grain quality in combination is a complicated process and difficult to achieve when relying on only one or several functional genes , thus the selection expertise of the breeder remains critical | Matching Sentences:
