    Notes: Resistance to pea seed-borne mosaic virus (PSbMV) pathotype P-1 in peas is conferred by sbm1 with recessive inheritance. PSbMV is an economically important pathogen with world-wide distribution that causes significant losses in pea yield and reduces seed and produce quality. The sbm1 gene was previously mapped to linkage group VI on molecular linkage maps of the pea genome. To improve plant breeders’ ability to develop varieties resistant to PSbMV, two random amplified polymorphic DNA markers (G05_2537 and L01_910) and one restriction fragment length polymorphism (P446) linked to sbm1 have been identified. The genomic sequences for these markers have been characterized and the information used to develop three simple polymerase chain reaction-based STS (sequence tagged site) assays. Linkage analysis in two F2 populations showed that the most tightly linked of these three STS loci (sG05_2537) is approximately 4 cM from sbm1. Characterization of a collection of resistant and susceptible germplasm demonstrated a strong correlation between STS alleles and sbm1 alleles, indicating the utility of these markers for marker-assisted selection in breeding programmes using a range of germplasm sources.

    Influence of pinealectomy on corticotropin (ACTH) (1980)

    Notes: Summary Sensory deprivation produced by removing the eyes and olfactory bulbs in male rats allowed pinealectomy to markedly augment the post-adrenalectomy elevation of ACTH levels. Pineal removal or sensory deprivation separately did not have this effect. Thus, intact sensory input and an intact pineal gland are independently capable of restricting the post-adrenalectomy rise in ACTH levels.

    Notes: Summary Male and female gerbils were implanted s.c. with a pellet containing 2 mg melatonin/23 mg beeswax every 2 weeks for a total of 3 implants. A significant depression of ovarian and uterine weight was noted in female gerbils receiving melatonin implants. In the melatonin-treated male gerbils, growth of the accessory organs was significantly inhibited although testis size was not depressed.

    Notes: Summary Previous studies show that the suppression of gonadal function in blind-anosmic rats is dependent on the pineal gland. The present results demonstrate that in young female rats both the pineal gland and dual sensory deprivation have additional independent antigonaldal effects.

    Notes: Abstract  Pea (Pisum sativum L.) sequences that are analogous to the conserved nucleotide binding site (NBS) domain found in a number of plant disease resistance genes (R-genes) were cloned. Using redundant oligonucleotide primers and the polymerase chain reaction (PCR), we amplified nine pea sequences and characterised their sequences. The pea R-gene analog (RGA)- deduced amino acid sequences demonstrated significant sequence similarity with known R-gene sequences lodged in public databases. The genomic locations of eight of the pea RGAs were determined by linkage mapping. The eight RGAs identified ten loci that mapped to six linkage groups. In addition, the genomic organization of the RGAs was inferred. Both single-copy and multicopy sequence families were present among the RGAs, and the multicopy families occurred most often as tightly linked clusters of related sequences. Intraspecific copy number variability was observed in three of the RGA sequence families, suggesting that these sequence families are evolving rapidly. The genomic locations of the pea RGAs were compared with the locations of known pea R-genes and sym genes involved in the pea-rhizobia symbiosis. Two pea RGAs mapped in the genomic region containing a pea R-gene, Fw, and four pea RGAs mapped in regions of the genome containing sym genes.

    Notes: Abstract Quantitative trait loci (QTLs) affecting seed weight in pea (Pisum sativum L.) were mapped using two populations, a field-grown F2 progeny of a cross between two cultivated types (‘Primo’ and ‘OSU442-15’) and glasshouse-grown single-seed-descent recombinant inbred lines (RILs) from a wide cross between a P. sativum ssp. sativum line (‘Slow’) and a P. sativum ssp. humile accession (‘JI1794’). Linkage maps for these crosses consisted of 199 and 235 markers, respectively. QTLs for seed weight in the ‘Primo’ x ‘OSU442-15’ cross were identified by interval mapping, bulked segregant analysis, and selective genotyping. Four QTLs were identified in this cross, demonstrating linkage to four intervals on three linkage groups. QTLs for seed weight in the ‘JI1794’ x ‘Slow’ cross were identified by single-marker analyses. Linkage were demonstrated to four intervals on three linkage groups plus three unlinked loci. In the two crosses, only one common genomic region was identified as containing seed-weight QTLs. Seed-weight QTLs mapped to the same region of linkage group III in both crosses. Conserved linkage relationships were demonstrated for pea, mungbean (Vigna radiata L.), and cowpea (V. unguiculata L.) genomic regions containing seed-weight QTLs by mapping RFLP loci from the Vigna maps in the ‘Primo’ x ‘OSU442-15’ and ‘JI1794’ x ‘Slow’ crosses.

    Notes: Abstract  A linkage map of the pea (Pisum sativum L.) genome is presented which is based on F2 plants produced by crossing the marrowfat cultivar ‘Primo’ and the blue-pea breeding line ‘OSU442-15’. This linkage map consists of 209 markers and covers 1330 cM (Kosambi units) and includes RFLP, RAPD and AFLP markers. By mapping a number of anchor loci, the ‘Primo’בOSU442-15’ map has been related to other pea linkage maps. A feature of the map is the incorporation of 29 loci representing genes of known function, obtained from other laboratories. The map also contains RFLP loci detected using sequence-characterized cDNA clones developed in our laboratory. The putative identities of 38 of these cDNA clones were assigned by examining public-sequence databases for protein or nucleotide-sequence similarities. The conversion of sequence-characterized pea cDNAs into PCR-amplifiable and polymorphic sequence-tagged sites (STSs) was investigated using 18 pairs of primers designed for single-copy sequences. Eleven polymorphic STSs were developed.

    The transfer of a powdery mildew resistance gene from Hordeum bulbosum L to barley (H. vulgare L.) chromosome 2 (2I) (1995)

    Notes: Abstract Hordeum bulbosum L. is a source of disease resistance genes that would be worthwhile transferring to barley (H. vulgare L.). To achieve this objective, selfed seed from a tetraploid H. vulgare x H. bulbosum hybrid was irradiated. Subsequently, a powdery mildew-resistant selection of barley phenotype (81882/83) was identified among field-grown progeny. Using molecular analyses, we have established that the H. bulbosum DNA containing the powdery mildew resistance gene had been introgressed into 81882/83 and is located on chromosome 2 (2I). Resistant plants have been backcrossed to barley to remove the adverse effects of a linked factor conditioning triploid seed formation, but there remains an association between powdery mildew resistance and non-pathogenic necrotic leaf blotching. The dominant resistance gene is allelic to a gene transferred from H. bulbosum by co-workers in Germany, but non-allelic to all other known powdery mildew resistance genes in barley. We propose Mlhb as a gene symbol for this resistance.
