Significant advances recently occurred in Coffea canephora research, such as the completion of its full genome sequencing. The
information generated can be used in advanced molecular approaches for genetic improvement, like genome-wide selection
programs (GWS). The purpose of this study was the phenotyping and genotyping of 403 C. canephora individuals cultivated at
Cerrado climatic conditions characterized by a relatively high altitude (>1000m) and a long dry season. Phenotypic evaluations
started in 2012 with the measurement of several agronomical traits such as vigor, secondary branching, leaf-rust susceptibility and
precocity of fruit maturation. Production (evaluated in fruit liters) of each plant was also measured during two consecutive years...

Cross-disciplinary approaches for measuring parasitic helminth viability and phenotype
Provedor de dados: 42
Autores: Peak,Emily; Hoffmann,Karl F.
Parasitic worms (helminths) within the Phyla Nematoda and Platyhelminthes are responsible for some of the most debilitating and
chronic infectious diseases of human and animal populations across the globe. As no subunit vaccine for any parasitic helminth is
close to being developed, the frontline strategy for intervention is administration of therapeutic, anthelmintic drugs. Worryingly,
and unsurprising due to co-evolutionary mechanisms, many of these worms are developing resistance to the limited compound
classes currently being used. This unfortunate reality has led to a renaissance in next generation anthelmintic discovery within
both academic and industrial sectors. However, a major bottleneck in this process is the lack of quantitative methods for...

Phenotype and genotype correlation of the microconversion from the CYP21A1P to the CYP21A2
gene in congenital adrenal hyperplasia
Provedor de dados: 56
Autores: Torres,N.; Mello,M.P.; Germano,C.M.R.; Elias,L.L.K.; Moreira,A.C.; Castro,M.
Deficiency of 21-hydroxylase is the most common form of congenital adrenal hyperplasia (CAH-21OH). We determined by
allele-specific PCR the frequency of microconversion in the CYP21A2 gene in 50 Brazilian patients with the classical (salt
wasting: SW and simple virilizing: SV) forms and nonclassical (NC) form of CAH-21OH and correlated genotype with
phenotype. Genotypes were classified into three mutation groups (A, B, and C) based on the amount of enzymatic activity in in
vitro studies using adrenal cells. In 94 unrelated alleles, we diagnosed 76% of the affected alleles after screening for 7
microconversions. The most frequent point mutations observed in this series were I172N (19%), V281L (18%), and
IVS2,A/C>G,-12 (15%). In the SW form, the most...

We determined the frequency of large rearrangements and point mutations in 130 Brazilian patients with 21-hydroxylase
deficiency and correlated genotype with phenotype. The frequency of CYP21 deletions was lower (4.4%) than in most of the
previous series described, whereas the frequency of large gene conversions was similar to the frequency reported in the literature
(6.6%). The most frequent point mutations were I2 splice (41.8% in salt wasting - SW), I172N (32.6% in simple virilizing - SV)
and V281L (40.2% in the late onset form - LO). The frequency of the nine most common point mutations was similar to that
reported for other countries. The 93 fully genotyped patients were classified into 3 mutation groups based on the degree of
enzymatic activity...

On 398 river buffalo samples, randomly collected in distinct breeding areas of the Campania region, high-resolution analytical
systems were used to identify both qualitative and quantitative variations of the Hb phenotype. Polyacrylamide gel isoelectric
focusing and HPLC were used to determine the ratio between HBA1 and HBA2 globin chains; restriction endonuclease analysis
was performed to assess whether quantitative variations in Hb bands were related to an unusual number of a-globin genes. In the
two buffalo subpopulations, allele frequencies of the alpha and beta globin systems were calculated, and F statistics (FIS, FIT and
FST) were estimated as parameters of genetic diversity. The results suggest that: i) as shown by RFLP analysis, only a couple of...

Cystic fibrosis (CF) is caused by CFTR (cystic fibrosis transmembrane conductance regulator) gene mutations. We ascertained
five patients with a novel complex CFTR allele, with two mutations, H939R and H949L, inherited in cis in the same exon of
CFTR gene, and one different mutation per patient inherited in trans in a wide population of 289 Caucasian CF subjects from
South Italy. The genotype-phenotype relationship in patients bearing this complex allele was investigated. The two associated
mutations were related to classical severe CF phenotypes.

conditions
Provedor de dados: 35
Autores: Dhillon, N.P.S.; Kumar, J.
Five melon (Cucumis melo L.) progenies segregating for five male-sterile genes (ms-1, ms-2, ms-3, ms-4, and ms-5) along with
two male-fertile cultivars were evaluated for phenotypic variation in expression of fertility in sub-tropical field conditions, for two
years. Male-fertile plants of three progenies of ms-1, ms-2, and ms-3 were phenotypically unstable and produced more
male-sterile flowers than plants of normal male-fertile cultivars. Progenies of ms-4 and ms-5 were stable for the expression of
male-fertile plants.

Phenotypic plasticity and fitness in egg parasitoids
Provedor de dados: 82
Autores: Boivin,Guy.
Several proxies can be used to estimate the fitness of egg parasitoids: size, longevity, fecundity, mating ability and vagility. All
these proxies are positively correlated with the lifetime fitness gain of an individual. However, the phenotypic plasticity, which is
the ability of a genotype to produce distinct phenotypes depending on environmental conditions, may alter the value of these
proxies. Host related factors (host species and quality), competition and duration of development will influence the proxies
expressed by a given phenotype. When the phenotype is modified by the temperature at which an individual develops, the
resulting phenotype will vary based on the life history strategy of the parasitoid. While in koinobiont species an increase in...

year through the implementation of genomic selection. Now proven to work in dairy cattle breeding, the challenge remains for the
beef industry to successfully implement this technology. The primary challenge in beef cattle is the required resource population
that relates genomic profile to phenotypic performance, which is quite large and its establishment will require collaboration or a

BACKGROUND: Morphological variability can lead to serious taxonomic problems in species with wide distribution ranges.
Although morphological variability is partly due to ontogenetic programming, abiotic variables can also exert a significant effect
on micro- and macromorphological characters. in this paper, we studied the morphological variability (43 characters) of Cosmos
bipinnatus associated to different vegetation types in central Mexico. We searched for significant correlations between the overall
morphology of C. bipinnatus and abiotic variables such as altitude and soil parameters (pH, organic matter content,
NH4,NO3,PO4, total N and total P content). We also analyzed the Simplified Relative Distance Plasticity index (RDPIs).

Genetic control of seed dormancy and pre-harvest sprouting in wheat
Provedor de dados: 63
Autores: Andreoli,Claudinei; Bassoi,Manoel Carlos; Brunetta,Dionisio.
Pre-harvest sprouting (PHS) damage leads to occasional massive losses in all wheat producing areas, causing downgrading of
grain quality, that severely limits end-use applications and results in substantial financial losses to farmers and food processors.
Red grain color is a traditional marker for resistance to sprouting in wheat breeding programs, however red-grained genotype
alone does not always guarantee effective resistance. The objective of this work was to find genes for resistance to PHS and
investigate its inheritance in Brazilian wheat cultivars. Genetic variation for dormancy was investigated in the parents, F1 and 300
F2 lines derived from the cross Frontana × OR1 and its reciprocal. The germination/dormancy sprouted grains was...
