Griffiths et al. AMP1 is involved in development of seed dormancy in arabidopsis

ABSTRACT: Total RNA was extracted from arabidopsis thaliana (Columbia) seeds 10 days after pollination from 2 sets of 3 biological replicates of wild-type and mutant plants. Mutant plants were AMP1-1 mutants carrying a stop codon in the middle of the gene resulting in truncated protein.

ORGANISM(S): Arabidopsis thaliana

ALTERED MERISTEM PROGRAM 1 is involved in development of seed dormancy in Arabidopsis.

Griffiths Jayne J Barrero Jose M JM Taylor Jennifer J Helliwell Chris A CA Gubler Frank F

PloS one 20110526 5

Mutants in the rice PLASTOCHRON 3 and maize VIVIPAROUS 8 genes have been shown to have reduced dormancy and ABA levels. In this study we used several mutants in the orthologous gene ALTERED MERISTEM PROGRAM 1 (AMP1) to determine its role in seed dormancy in Arabidopsis. Here we report that there are accession-specific effects of mutations in AMP1. In one accession, amp1 mutants produce seeds with higher dormancy, while those in two other accessions produce seeds of lower dormancy. These accessio ...[more]

Sarig et al. SOFT syndrome caused by a mutation in POC1A

Project description:Disproportionate short stature refers to a heterogeneous group of hereditary disorders, which are classified according to their mode of inheritance, their clinical skeletal and non-skeletal manifestations, and their radiological characteristics. In the present study, we report on a novel autosomal recessive osteocutaneous disorder that we termed short stature-onychodysplasia-facial dysmorphism-hypotrichosis (SOFT) syndrome. we identified a homozygous point mutation (p.L171P) in POC1A (Centriolar Protein Homolog A). The mutation affects a highly conserved amino acid residue and is predicted to interfere with protein function. To gain insight into the pathomechanisms underlying the deleterious effect of the causative mutation, we compared transcription profiles of patient and control fibroblasts.

Nkya et al 2014 - Insecticide resistance mechanisms associated with different environments in the malaria vector Anopheles gambiae. A case study in Tanzania

Project description:Nine Anopheles gambiae populations were sampled in three areas of Tanzania showing contrasting agriculture activity, urbanization and usage of insecticides for vector control. Insecticide resistance levels were measured in larvae and adults through bioassays with deltamethrin, DDT and bendiocarb. A microarray approach was used for identifying transcription level variations associated to different environments and insecticide resistance. the Ifakara strain originating from central Tanzania and susceptible to all insecticides was used as a reference strain.

Transcript profiling of the wild type Arabidopsis grown under different photoperiods

Project description:Arabidopsis rosette leaves were harvested from plants grown under different photoperiods under 100 M-5mol photons m-2 s-1 at 20 M-0C. In the first experiment plants grown under short day conditions 8L/16D (8 h light / 16 h dark) for 4 weeks were compared with plants grown under long day (16L/8D) for 3 weeks. In the second experiment plants grown under 12L/12D for 2 weeks were compared with plants grown first 2 weeks under 12L/12D and then two days under short day (8L/16D) conditions.
