We describe a novel mutant of Arabidopsis, Flo10, which is the result of a recessive allele, flo10, in the nuclear gene FLO10. The first three organ whorls (sepals, petals, and stamens) of Flo10 flowers are normal, but the fourth, gynoecial whorl is replaced by two to eight stamens or stamen-carpel intermediate organs. Studies of ontogeny suggest that the position of the first six of these four...

Background & Aims: To investigate the association of CFI p.Gly119Arg polymorphism with Age-related macular degeneration (AMD). Materials & Methods: In this case-control study, the association of p.Gly119Arg polymorphism in CFI gene was investigated in 65 patients suffering from AMD and150 healthy age, sex and ethnicity matched unrelated people as control group. Both of the case and cont...

the miru-vntr polymorphism and katg463 mutation are used to genotype the mycobacterium tuberculosis, but the correlation between them and inh-resistance were unknown. this study was aimed to explore whether etre polymorphism and katg463 mutation could predict the inh-resistance, and the relationship between etre polymorphism and katg463 mutation.the etre, katg463 mutation and drug resistance in...

Papaya (Carica papaya L.) plants are polygamous, with female, male, and hermaphroditic flowers. To understand the roles of MADS-box genes in flower development and sex determination, we cloned cDNAs of E-class genes CpMADS1 and CpMADS3 and a TM6 lineage of the B-class gene CpMADS2 from young flower buds of papaya. Reverse transcription-polymerase chain reaction (RT-PCR) and real-time PCR analys...

We used electrophysiologic criteria to identify median mononeuropathy (MM) at the nondominant wrist among 414 patients enrolled in a multicenter study of patients with mild diabetic neuropathy according to consensus recommendations. Patients with absent sural or peroneal responses or greater than mild symptoms of carpal tunnel syndrome were ineligible. Ninety-five of 414 participants (23%) fulf...

Ethylene is required for climacteric fruit ripening. Inhibition of ethylene biosynthesis genes, 1-aminocyclopropane-1-carboxylate (ACC) synthase and ACC oxidase, prevents or delays ripening, but it is not known how these genes are modulated during normal development. LeHB-1, a previously uncharacterized tomato homeobox protein, was shown by gel retardation assay to interact with the promoter of...

The carpel (car) mutation affects the morphology of reproductive organs in Arabidopsis thaliana. car flowers have an increased number of carpels, on average 2.7 +/- 0.8 instead of two in the wild type. Through allelism test with fon1-3 and analysis of the methylation state of the SUPERMAN (SUP) gene in car mutants, we show that car is an epi-mutation of SUP. The methylation pattern of car is cl...

Infestation of young apple fruits by the larvae of the peach fruit moth, Carposina sasakii Matsumura (Lepidoptera: Carposinidae), was studied by a small dedicated micro-magnetic resonance imaging (MRI) apparatus using the three-dimensional (3D) gradient-echo method and the two-dimensional (2D) and 3D spin-echo methods. Changes from a young larva at 1.8 mm in length to a mature one ready to leav...

In plants, organs are generated post-embryonically from highly organized structures known as meristems. Cell division in the meristem is closely integrated with cell fate specification and organ formation. The presence of multiple cyclin-dependent kinases (CDKs) and their partner cyclins in plants and other multicellular organisms probably reflects the complexity of cell cycle regulation within...
