1. Glyphosate Resistance Affect the Physiological Quality of Conyza bonariensis seeds
RESUMO: A alta capacidade de produção e dispersão de sementes e a resistência ao glyphosate estão entre os principais fatores que tornaram a buva (Conyza bonariensis) uma das mais importantes e dispersas plantas daninhas no mundo. Populações de plantas resistentes a herbicidas podem apresentar penalidades em função das alterações moleculares, fisi

2. Establishment and optimization of a hydroponic system for root morphological and nutritional analysis of citrus
ABSTRACT The hydroponic growth system is a convenient platform for studying whole plant physiology, especially for root morphological and nutritional analysis. However, we found that most hydroponic systems described in the literature are not suitable for citrus plants. In this study, a hydroponic system for citrus was designed, comprising three principal co

3. Oxytocin and arginine vasopressin systems in the domestication process
Abstract Domestication is of unquestionable importance to the technological revolution that has given rise to modern human societies. In this study, we analyzed the DNA and protein sequences of six genes of the oxytocin and arginine vasopressin systems (OXT-OXTR; AVP-AVPR1a, AVPR1b and AVPR2) in 40 placental mammals. These systems play an important role in t

4. Genetics of osteoporosis: searching for candidate genes for bone fragility
ABSTRACT The pathogenesis of osteoporosis, a common disease with great morbidity and mortality, comprises environmental and genetic factors. As with other complex disorders, the genetic basis of osteoporosis has been difficult to identify. Nevertheless, several approaches have been undertaken in the past decades in order to identify candidate genes for bone

5. Genetic basis of triatomine behavior: lessons from available insect genomes
Triatomines have been important model organisms for behavioural research. Diverse reports about triatomine host search, pheromone communication in the sexual, shelter and alarm contexts, daily cycles of activity, refuge choice and behavioural plasticity have been published in the last two decades. In recent times, a variety of molecular genetics techniques h

6. A non-invasive plant-based probe for continuous monitoring of water stress in real time: a new tool for irrigation scheduling and deeper insight into drought and salinity stress physiology
The non-invasive, magnetic leaf patch clamp pressure probe (also termed ZIM-probe) allows for the first time to measure continuously turgor pressure changes of plant leaves over long periods of time with high precision and in real time. The probe has become an important tool in plant physiology, molecular biology and ecology, but also in agriculture because

7. Circadian rhythms in insect disease vectors
Organisms from bacteria to humans have evolved under predictable daily environmental cycles owing to the Earth’s rotation. This strong selection pressure has generated endogenous circadian clocks that regulate many aspects of behaviour, physiology and metabolism, anticipating and synchronising internal time-keeping to changes in the cyclical environment. I

8. Insights into the Melipona scutellaris (Hymenoptera, Apidae, Meliponini) fat body transcriptome
The insect fat body is a multifunctional organ analogous to the vertebrate liver. The fat body is involved in the metabolism of juvenile hormone, regulation of environmental stress, production of immunity regulator-like proteins in cells and protein storage. However, very little is known about the molecular mechanisms involved in fat body physiology in sting

9. Proteomic profiling of liver from Elaphe taeniura, a common snake in eastern and southeastern Asia
Snake liver has been implicated in the adaptation of snakes to a variety of habitats. However, to date, there has been no systematic analysis of snake liver proteins. In this study, we undertook a proteomic analysis of liver from the colubrid snake Elaphe taeniura using a combination of two-dimensional electrophoresis (2-DE) and matrix-assisted laser desorpt

10. Análise do mRNA da proteína BMP-15 e IGF-2 em oócitos e células do cumulus de ovelhas do semiárido pernambucano. / Analysis of mRNA expression of BMP-15 and IGF-2 proteins in oocytes and cumulus cells of sheep in semi-arid state of Pernambuco.
Two experiments were conducted to analyze the expression of genes related to follicular development and subsequent reproductive efficiency in oocytes and cumulus cells in two distinct phases of folliculogenesis. Ovaries of native breeds of sheep slaughtered in the abattoir in Caruaru/PE were collected and transported to the Laboratory of Applied Molecular An

11. Avaliação dos lipídeos de membrana e das ORFs dos contratransportadores Na+/H+ e Na+/Ca2+ associados a mecanismos de adaptação à halofilia em Halococcus morrhuae
Soil saliniy is a major factor in reducing plant growth and, consequently, their agricultural productivity. Most of the studies in the literature presents a strategy for reducing the effects of improving salt tolerance in plants for the production of osmolytes and stress proteins, and there are few studies aimed at increasing salt tolerance by restoring ioni

12. Differentially expressed genes and miRNA identification in pig skeletal muscle / Identificação de genes diferencialmente expressos e miRNAs em músculo esquelético de suínos
The pig (Sus scrofa) is considered an important animal for meat production. This interest revolves around the potential for muscle growth, which usually is associated with certain characteristics during prenatal myogenesis. To study the genes responsible for these characteristics, expressed sequence tags (EST) provide direct information about the transcripto
