1. Effects of Citrus Sudden Death Disease on Fatty Acid Profile of Orange Tree Bark
Citrus sudden death (CSD) is a disease that has affected millions of orange trees in Brazil, leading to economic losses in the order of billions of US dollars. This article examines the effects of CSD on the fatty acid composition of triacylglycerides (TAG) extracted from rootstock and scion bark. The fatty acid profile determined by gas chromatography showe

2. Phytotoxicity and physiological changes in Schinus terebinthifolius Raddi under simulated 2,4-D drift and dicamba
ABSTRACT The use of auxin mimics herbicides in agriculture is widespread in a great diversity of crops. The indiscriminate use of herbicides can cause adverse effects in the plants. Among the plant species that stand out for being highly competitive and resistant to biotic and abiotic stresses, it is the brazilian peppertree (Schinus terebinthifolius Raddi.)

3. Effect of high temperature and recovery from stress on crop–weed interaction
ABSTRACT Biotic and abiotic stresses, either individually or in combination, may affect soybean growth and development negatively, besides competitiveness with weeds. This study aimed at evaluating the effect of heat stress and plant recovery on crop–weed interaction by analyzing growth variables. Experiments were set up as replacement series of soybean wi

4. Morphology of yellow passion fruit seedlings submitted to triazole induced growth inhibition
RESUMO A restrição do vigor vegetativo de mudas pode ser uma estratégia para otimização da modulação frente à estresses bióticos e abióticos após o transplantio. O objetivo desse estudo foi verificar se os parâmetros morfológicos de mudas de maracujazeiro amarelo (Passiflora edulis) são afetados pela restrição do crescimento com aplicação d

5. Genome-wide identification and characterization of R2R3-MYB genes in Medicago truncatula
Abstract MYB is a large family of plant transcription factors. Its function has been identified in several plants, while there are few reports in Medicago truncatula. In this study, we used RNA-seq data to analyze and identify R2R3-MYB genes in the genome of Medicago truncatula. Phylogenetic analysis classified 150 MtMYB genes into 21 subfamilies with homolo

6. 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

7. Phenotypic Characterization and Genetic Diversity of Sugarcane Varieties Cultivated in Northern Karnataka of India based on Principal Component and Cluster Analyses
Abstract: Sugarcane is a major commercial crop grown in India and across the world. Hence, several elite varieties have been developed now-a-days to overcome many obstacles including abiotic stresses and diseases. The present study was undertaken to screen genetic variation among twenty four sugarcane varieties that are commonly cultivated across Northern Ka

8. Chlorophyll a fluorescence and leaf temperature are early indicators of oil palm diseases
ABSTRACT Bud rot (BR) caused by Phytophthora palmivora and lethal wilt (LW) whose causal agent is unknown, are two diseases currently posing a threat to the oil palm ( Elaeis guineensis . Jacq) industry. BR, first reported in 1964, has destroyed more than 85,000 ha. LW, first reported in 1994 in the Llanos Orientales in Colombia, has destroyed more than 5,00

9. [PROVISIONAL] Molecular characterization and transcription analysis of DNA methyltransferase genes in tomato (Solanum lycopersicum)
Abstract DNA methylation plays an important role in plant growth and development, gene expression regulation and maintenance of genome stability. However, only little information regarding development- or stress-related DNA methyltransferases (MTases) genes is available in tomato. Here, we report the analysis of nine tomato MTases which were categorized into

10. [PROVISIONAL] Genome-wide analysis of the transcriptional response to drought stress in root and leaf of common bean
Abstract Genes related to the response to drought stress in leaf and root tissue of drought-susceptible (DS) and tolerant (DT) genotypes were characterized by RNA-Seq. In total, 54,750 transcripts, representative of 28,590 genes, were identified; of these, 1,648 were of high-fidelity (merge of 12 libraries) and described for the first time in the Andean germ

11. EFFECTS OF COMPETITION AND WATER DEFICIENCY ON SUNFLOWER AND WEED GROWTH
RESUMO No ambiente agrícola é comum a ocorrência de estresse de origem biótica e abiótica, como a interferência das plantas daninhas e o déficit hídrico no solo, respectivamente. Porém, pouco se conhece sobre os efeitos da interação desses estresses sobre o crescimento de espécies cultivadas e daninhas. Desta maneira, objetivou-se com este trabal

12. Genetic progress, adaptability and stability of maize cultivars for value of cultivation and use trials
ABSTRACT. Maize breeding programs conduct multi-environment trials every year to assess the performance of new cultivars in pre-releasing tests. The data are combined across sites and seasons to perform a joint analysis in order to obtain information that will help breeders to select the best cultivars for different environments. Beyond this, it is essential
