1. Differential gene expression of pectin esterase and changes in pectin during development and ripening stages of fruit in selected cultivars of banana
Abstract Pectin is a very important ingredient in food processing. The present study was designed to find out the changes taken place in pectin content during development and ripening phases of banana fruit. The expression of gene (pectin esterase) was also observed during development and ripening. Five exotic cultivars namely William, Brazilian, G-Naine, Ba

3. Ammopiptanthus mongolicus stress-responsive NAC gene enhances the tolerance of transgenic Arabidopsis thaliana to drought and cold stresses
Abstract Drought and cold are the primary factors limiting plant growth worldwide. The Ammopiptanthus mongolicus NAC11 (AmNAC11) gene encodes a stress-responsive transcription factor. Expression of the AmNAC11 gene was induced by drought, cold and high salinity. The AmNAC11 protein was localized in the nucleus and plays an important role in tolerance to drou

4. Does the Introgression of Bt Gene Affect Physiological Cotton Response to Water Deficit?
RESUMO: O déficit hídrico pode afetar a expressão de proteínas que promovem o controle de lepidópteras no algodoeiro. Entretanto, não é conhecida a resposta de cultivares de algodão Bt e convencionais ao déficit hídrico, o que poderia afetar o potencial de competição com plantas daninhas. O objetivo deste trabalho foi avaliar a resposta de cultiv

5. Common resistance to Fusarium head blight in Brazilian wheat cultivars
ABSTRACT: Mycotoxin levels in Fusarium head blight (FHB) infections can be difficult to quantify. The relationship between mycotoxin and disease is not consistent and it is not clear if wheatpathogen interaction is of significance in regions where more than one Fusarium species with distinct trichothecene production ability co-exists. This study aimed to inv

6. Oxidative damage and photosynthetic impairment in tropical rice cultivars upon exposure to excess iron
ABSTRACT Iron plays a pivotal role in the redox reactions of photosynthesis and metabolic processes such as chlorophyll synthesis. Iron availability in waterlogged soils can reach toxic levels and promote oxidative stress. Fe toxicity is the most concerning of stresses for rice in many lowland environments around the world and may cause severe impairments in

7. Differential leaf gas exchange performance of mango cultivars infected by different isolates of Ceratocystis fimbriata
ABSTRACT Caused by the vascular fungus Ceratocystis fimbriata, mango wilt is considered to be one of the most serious threats in mango-producing regions worldwide. However, changes in leaf gas exchange level and the mechanisms underlying host responses to this fungal infection remain poorly described. This study aimed to evaluate potential changes in the lea

8. New sources of resistance to Myrothecium roridum and Podosphaeria xanthii in yellow melon
The aim of this study was to identify sources of resistance toMyrothecium roridumand Podosphaeria xanthii.Initially, 86 inbred lines of the crossing AM-04 x Goldex, 91 inbred lines of the crossing AM-12 x Rochedo, and 75 inbred lines of the crossing ACP x AF-646 were evaluated. The trials were carried out in a greenhouse in a randomized block design with fiv

9. Differential detection of transposable elements between Saccharum species
Cultivars of sugarcane (Saccharum) are hybrids between species S. officinarum (x = 10, 2n = 8x = 80) and S. spontaneum (x=8,2n=5-16x =40-128). These accessions have 100 to 130 chromosomes, 80-85% of which are derived from S. officinarum, 10-15% from S. spontaneum, and 5-10% are possible recombinants between the two genomes. The aim of this study was to analy

10. Colonization of Greek olive cultivars' root system by arbuscular mycorrhiza fungus: root morphology, growth, and mineral nutrition of olive plants
Rooted leafy cuttings of three Greek olive (Olea europaea L.) cultivars (Koroneiki, Kothreiki and Chondrolia Chalkidikis) were grown for six months in three soil types, in an experimental greenhouse, in order to investigate: i) if their root system was colonized by arbuscular mycorrhiza fungus (AMF) genus and, ii) if genotypic differences concerning growth a

11. Introduction of the rd29A: AtDREB2A CA gene into soybean (Glycine max L. Merril) and its molecular characterization in leaves and roots during dehydration
The loss of soybean yield to Brazilian producers because of a water deficit in the 2011-2012 season was 12.9%. To reduce such losses, molecular biology techniques, including plant transformation, can be used to insert genes of interest into conventional soybean cultivars to produce lines that are more tolerant to drought. The abscisic acid (ABA)-independent

12. Determinação voltamétrica de ricina em mamona usando carbono vítreo e diamante dopado com boro / Voltammetric determination of ricin in castor bean using gassy carbon and boron doped diamond.
Ricin (RCA 60) is an inhibitor of ribosomes protein toxic, of class II, extracted from castor bean endosperm of the seed, consisting of two peptide chains (RCA-A 30 and RCA-B 30) linked by a disulfide bridge covalently formed by the combination of 17 amino acid residues. Its toxicity has been observed in animals, insects and humans, being by inhalation, inge
