Increased [CO] Causes Changes in Physiological and Genetic Responses in C Crops: A Brief Review.

Climate change not only worries government representatives and organizations, but also attracts the attention of the scientific community in different contexts. In agriculture specifically, the cultivation and productivity of crops such as sugarcane, maize, and sorghum are influenced by several environmental factors. The effects of high atmospheric concentration of carbon dioxide ([CO]) have been the subject of research investigating the growth and development of C plants.

Molecular Mechanisms Underlying Sugarcane Response to Aluminum Stress by RNA-Seq.

Some metals are beneficial to plants and contribute to critical physiological processes. Some metals, however, are not. The presence of aluminum ions (Al) can be very toxic, especially in acidic soils.

Microtranscriptome analysis of sugarcane cultivars in response to aluminum stress.

Although several metallic elements are required for plant growth, excessive amounts of aluminum ions (Al3+) can result in the inhibition of root growth, thus triggering water and nutrient deficiencies. Plants under stress undergo gene expression changes in specific genes or post-transcriptional gene regulators, such as miRNAs, that can lead to stress tolerance. In this study, we investigated the miRNAs involved in the response of sugarcane to aluminum stress.

Overexpression of an evolutionarily conserved drought-responsive sugarcane gene enhances salinity and drought resilience.

Background And Aims: Improving drought adaptation is more pressing for crops such as sugarcane, rice, wheat and maize, given the high dependence of these crops on irrigation. One option for enhancing adaptation to water limitation in plants is by transgenic approaches. An increasing number of genes that are associated with mechanisms used by plants to cope with water scarcity have been discovered.

Genetic diversity and chemical variability of Lippia spp. (Verbenaceae).

Background: The genus Lippia comprises 150 species, most of which have interesting medicinal properties. Lippia sidoides (syn. L.

The natural plant stress elicitor cis-jasmone causes cultivar-dependent reduction in growth of the stink bug, Euschistus heros and associated changes in flavonoid concentrations in soybean, Glycine max.

To test the hypothesis that the plant stress related elicitor cis-jasmone (cJ) provides protection in soybean pods against the seed-sucking stink bug pest, Euschistus heros, the growth of E. heros on cJ-treated pods was investigated using three soybean cultivars differing in insect susceptibility, i.e.

CryGetter: a tool to automate retrieval and analysis of Cry protein data.

Background: For many years, the use of chemical agents to control crop pests has been degrading the environment, bringing problems to humans and all living things. An alternative to deal with the pests is the use of biopesticides, biological agents capable of controlling these harmful organisms. One kind of biopesticide is Bacillus thuringiensis, a Gram-positive bacterium that synthesizes a protein that, when ingested by the pests, kills them and does not harm other species.

A novel stress-induced sugarcane gene confers tolerance to drought, salt and oxidative stress in transgenic tobacco plants.

Background: Drought is a major abiotic stress that affects crop productivity worldwide. Sugarcane can withstand periods of water scarcity during the final stage of culm maturation, during which sucrose accumulation occurs. Meanwhile, prolonged periods of drought can cause severe plant losses.

Serotonin receptor (5-HT 2A) and catechol-O-methyltransferase (COMT) gene polymorphisms: triggers of fibromyalgia?

Introduction: Fibromyalgia is a rheumatic syndrome characterized by diffuse and chronic pain associated with fatigue, sleep disorders, anxiety, depression, memory loss, and dizziness. Although the physiological mechanisms that control fibromyalgia have not been precisely established, neuroendocrine, genetic or molecular factors may be involved in fibromyalgia.

Objective: The aim of the present study was to characterize serotonin receptor (5-HT2A) and catechol-O-methyltransferase (COMT) gene polymorphisms in Brazilian patients with fibromyalgia and to evaluate the participation of these polymorphisms in the etiology of the disease.

Influence of catechol-O-methyltransferase (COMT) gene polymorphisms in pain sensibility of Brazilian fibromialgia patients.

Fibromyalgia syndrome (FS) is a rheumatic syndrome affecting to 2-3% of individuals of productive age, mainly women. Neuroendocrine and genetic factors may play a significant role in development of the disease which is characterized by diffuse chronic pain and presence of tender points. Several studies have suggested an association between FS, especially pain sensitivity, and polymorphism of the catechol-O-methyltransferase (COMT) gene.

Signal transduction-related responses to phytohormones and environmental challenges in sugarcane.

Background: Sugarcane is an increasingly economically and environmentally important C4 grass, used for the production of sugar and bioethanol, a low-carbon emission fuel. Sugarcane originated from crosses of Saccharum species and is noted for its unique capacity to accumulate high amounts of sucrose in its stems. Environmental stresses limit enormously sugarcane productivity worldwide.
