Abstract We introduce a new statistical model for patterns of linkage disequilibrium (LD) among multiple SNPs in population sample. The overcomes limitations existing approaches to understanding, summarizing, and interpreting LD by (i) relating directly the underlying recombination process; (ii) considering all loci simultaneously, rather than pairwise; (iii) avoiding assumption that necessarily has “block-like” structure; (iv) being computationally tractable huge genomic regions (up...
Seed size in higher plants is determined by the coordinated growth of embryo, endosperm, and maternal tissue. Several factors that act maternally to regulate seed have been identified, such as AUXIN RESPONSE FACTOR2, APETALA2, KLUH, DA1, but genetic molecular mechanisms these control are almost totally unknown. We previously demonstrated ubiquitin receptor DA1 acts synergistically with E3 ligase ENHANCER1 OF (EOD1)/BIG BROTHER final seeds Arabidopsis thaliana. Here, we describe another...
Although the control of organ size is a fundamental question in developmental biology, little known about genetic and molecular mechanisms that determine final seeds plants. We previously demonstrated ubiquitin receptor DA1 acts synergistically with E3 ligases DA2 ENHANCER1 OF (EOD1)/BIG BROTHER to restrict seed growth Arabidopsis thaliana. Here, we describe UBIQUITIN-SPECIFIC PROTEASE15 (UBP15), encoded by SUPPRESSOR2 (SOD2), which maternally regulate promoting cell proliferation...
Grain size and shape are two crucial traits that influence grain yield appearance in rice. Although several factors affect have been described rice, the molecular mechanisms underlying determination of still elusive. In this study we report WIDE AND THICK GRAIN 1 (WTG1) functions as an important factor determining The wtg1-1 mutant exhibits wide, thick, short heavy grains also shows increased number per panicle. WTG1 determines mainly by influencing cell expansion. encodes otubain-like...
• Control of organ size and shape by cell proliferation expansion is a fundamental developmental process, but the mechanisms that set determinate organs are largely unknown in plants. Molecular, genetic, cytological biochemical approaches were used to characterize roles Arabidopsis thaliana G protein γ subunit (AGG3) gene growth. Here, we describe A. AGG3, which promotes petal growth increasing period proliferation. Both N-terminal region C-terminal domains AGG3 necessary for function AGG3....
Grain size is one of key agronomic traits that determine grain yield in rice. Several regulators have been identified rice, but the mechanisms and remain largely unknown.Here we characterize a small (smg11) mutant which exhibits grains, dense panicles increased number grains per panicle. Cloning sequence analyses SMG11 gene reveal smg11 new allele DWARF2 (D2), encodes cytochrome P450 (CYP90D2) involved brassinosteroid biosynthetic pathway. Overexpression D2/SMG11 increases weight wild-type...
Abstract Control of organ size by cell proliferation and growth is a fundamental process, but the mechanisms that determine final organs are largely elusive in plants. We have previously revealed ubiquitin receptor DA1 regulates repressing Arabidopsis . Here we report mutant allele STERILE APETALA (SAP) suppresses da1-1 phenotype. show SAP an F-box protein forms part SKP1/Cullin/F-box E3 ligase complex controls promoting meristemoid cells. Genetic analyses suggest may act same pathway with...
Abstract Melatonin improves plant resistance to multiple stresses by participating in the biosynthesis of metabolites. Flavonoids are an important family secondary metabolites and widely recognized be involved resistance; however, crosstalk between melatonin flavonoid is largely unknown. We found that pigeon pea (Cajanus cajan) salt, drought, heat were significantly enhanced pre-treatment with melatonin. Combined transcriptome LC-ESI-MS/MS metabolomics analyses showed induced enrichment...
Abstract Brassinosteroid (BR) hormones are primarily perceived at the cell surface by leucine-rich repeat receptor-like kinase BRASSINOSTEROID INSENSITIVE1 (BRI1). In Arabidopsis thaliana, BRI1 has two close homologs, BRI1-LIKE1 (BRL1) and BRL3, respectively, which expressed in vascular tissues regulate shoot development. Here, we identify novel components of BRL3 receptor complex planta immunoprecipitation mass spectrometry analysis. Whereas ASSOCIATED KINASE1 (BAK1) several other known...
Abstract Obtaining genetic variation information from indica rice hybrid parents and identification of loci associated with heterosis are important for breeding. Here, we resequence 1,143 accessions mostly selected the superior cultivars China, identify variations, perform kinship analysis. We find different crossing patterns between 3- 2-line lines. By calculating frequencies parental differences (FPVDs), a more direct approach studying heterosis, that linked to which include 98 in 3-line...
Abstract Nitrate is not only an important nutrient but also a signaling molecule for plants. A few of key molecular components involved in primary nitrate responses have been identified mainly by forward and reverse genetics as well systems biology, however, many underlining mechanisms regulation remain unclear. In this study, we show that the expression NRT1.1 , which encodes sensor transporter (also known CHL1 NPF6.3 ), modulated NIN-like protein 7 (NLP7). Genetic analyses indicate NLP7...
In Arabidopsis (Arabidopsis thaliana), reduced expression of the transcriptional regulator PEAPOD2 (PPD2) results in propeller-like rosettes with enlarged and dome-shaped leaves. However, molecular cellular processes underlying this peculiar phenotype remain elusive. Here, we studied interaction between PPD2 NOVEL INTERACTOR OF JAZ (NINJA) demonstrated that ninja loss-of-function plants produce leaves similar to those ppd mutants but without increase size. We showed have a convex-shaped...
Abstract Seed size is a key agronomic trait that greatly determines plant yield. Elucidating the molecular mechanism underlying seed regulation also an important question in developmental biology. Here, we show KIX-PPD-MYC-GIF1 pathway plays crucial role control Arabidopsis thaliana . Disruption of KIX8/9 and PPD1/2 causes large seeds due to increased cell proliferation elongation integuments. interact with transcription factors MYC3/4 form KIX-PPD-MYC complex Arabidopsis. The associates...
Grain size and weight are directly associated with grain yield in crops. However, the molecular mechanisms that set final remain largely unknown. Here, we characterize two large mutants, grain8-1 (large8-1) grain8-2 (large8-2). LARGE8 encodes mitogen-activated protein kinase phosphatase1 (OsMKP1). Loss of function mutations OsMKP1 results grains, while overexpression leads to small grains. determines by restricting cell proliferation hulls. interacts deactivates 6 (OsMAPK6). Taken together,...
Grain size is an important agronomic trait, but our knowledge about grain determination in crops still limited. Endoplasmic reticulum (ER)-associated degradation (ERAD) a special ubiquitin proteasome system that involved degrading misfolded or incompletely folded proteins the ER. Here, we report SMALL GRAIN 3 (SMG3) and DECREASED SIZE 1 (DGS1), ERAD-related E2-E3 enzyme pair, regulate weight through brassinosteroid (BR) signaling pathway rice (Oryza sativa). SMG3 encodes homolog of...
