Hydrogen peroxide (H2O2) is an important ROS molecule (Reactive oxygen species) that serves as a signal of oxidative stress and activation signaling cascades result the early response plant to biotic stress. This can also be generated with application elicitors, stable molecules induce transduction hormonal pathways, which trigger induced resistance environmental In this work, we evaluated endogenous H2O2 production caused by salicylic acid (SA), chitosan (QN), elicitors in Capsicum annuum...
Common bean (Phaseolus vulgaris L.) is a leguminous in high demand for human nutrition and very important agricultural product. Production of common constrained by environmental stresses such as drought. Although conventional plant selection has been used to increase production yield stress tolerance, drought tolerance based on phenotype complicated associated physiological, anatomical, cellular, biochemical molecular changes. These changes are modulated differential gene expression. A...
Plant pathogens are responsible for large declines in agricultural production. Their control is carried out mainly by chemical and frequently proposed biological methods to reduce their environmental impact. On the other hand, plant-pathogen or microbe interactions generate multiple signals within plants activating defense mechanism, some of which can also be induced elicitors (protective molecules). Elicitor-induced plant signaling serves as a guide series intracellular events that end...
Trypsin inhibitors (TI), tannins, and lectins appear to have a role in preventing chronic diseases humans. The genetic variability of these traits common bean needs be ascertained order increase levels through breeding. TI, tannin, was determined five cultivars grown at locations Mexico. TI tannins contents colored beans that belong the Jalisco race were higher (11.1−11.9 trypsin units inhibited (TUI)/mg 29.0−38.1 mg catechin equivalent (CE)/g, respectively) than Durango (7.9−8.3 TUI/mg...
Phytophthora capsici, es el agente causal de la ‘marchitez del chile’ una las enfermedades más importantes este cultivo. Para establecer estrategias control eficientes necesario conocimiento diversidad patógeno, para esto, se realizó esta investigación cuyo objetivo fue determinar grado genética 30 aislados monozoospóricos obtenidos chile (Capsicum annuum L.) seis municipios estado Guanajuato, y dos cepas referencia. La variación determinó mediante técnica AFLP (en español: polimorfismo en...
Although several reports have described the occurrence of teleomorphic state Glomerella lindemuthiana (anamorph, Colletotrichum lindemuthianum), there has been a lack continuity in this research. To identify G. isolates capable developing state, 19 Mexican were analyzed. Three types response observed: (i) negative, where only mycelial growth with or without acervuli was observed; (ii) potential, addition to above, spherical perithecia-like structures (iii) positive, perithecia containing...
Chili pepper ( Capsicum annuum L.) production is affected by wilt and root rot, the most devastating disease caused pathogen complex of oomycete Phytophthora capsici Leon fungi Fusarium oxysporum Schlecht Rhizoctonia solani Kühn, infecting roots, stems, leaves, fruits. Fungicides are currently inefficient against this have a high environmental impact. The use elicitors sustainable alternative for inducing resistance to wilting rot. DNA fragments an organism’s own origin (conspecific or...
Abstract Phytophthora capsici is a highly destructive pathogen of crops. Although chemical pesticides are the most widely used strategy to counter phytopathogens, they have been inefficient combat P. and produced significant environmental health problems. Therefore, sustainable alternatives control soilborne pathogens, such as inhibitory effect self‐extracellular DNA (eDNA), proposed. This inhibition phenomenon has attributed action self‐eDNA damage‐associated molecular pattern (DAMP). Here,...
Screening for resistance to mixed infections with pepper huasteco virus (PHV) and golden mosaic (PepGMV) was carried out on plants representing wild accessions collected in different states of México. One accession Yucatán (BG-3821) corresponded Capsicum chinense Jacq., three from Michoacán (BG-3818), Tamaulipas (BG-3820), Sinaloa (BG-3819) were identified as C. annuum L. Forty-eight initially inoculated a 1:1 mix PHV PepGMV DNAs by biolistic method. Those that did not show typical...
A germin-like gene (CchGLP) cloned from geminivirus-resistant pepper (Capsicum chinense Jacq. Line BG-3821) was characterized and the enzymatic activity of expressed protein analyzed. The predicted consists 203 amino acids, similar to other proteins. highly conserved cupin domain typical germin boxes, one them containing three histidines glutamate, are also present in CchGLP. signal peptide first 18 N-terminal as well putative N-glycosylation site residues 44–47. CchGLP E. coli recombinant...
As a recently explored agricultural practice, the controlled elicitation of plants offers high potential in multiple crop needs as growth promotion, activation defenses and production specific metabolites. Extracellular DNA has been identified plant immune system elicitor but some aspects response have not explored. In present work, five treatments were applied tomato catalase, superoxide dismutase, phenylalanine ammonia lyase activities, hydrogen peroxide, total phenolics flavonoid contents...
Seven pepper ( Capsicum chinense Jacq . ) populations from the Yucatán Peninsula, México, that were selected a field screening for viral diseases tested huasteco geminivirus (PHV) resistance. Two (UX-SMH-1 and UX-SMH-24) displayed <50% of infection with PHV. Four plants did not show symptoms 3 months postinoculation using biolistic grafting methods. When leaf tissue these individuals was analyzed PHV quantitative PCR, it supported replication, thus, ineffective in symptomless may be...
The pathotypes of 17 isolates Colletotrichum lindemuthianum from the central region Mexico were characterized to determine genetic relationship among this and other regions Mexico, evaluate resistance present in elite germ plasm collection Phaseolus vulgaris at INIFAP. Eight identified, including pathotype 292, which is reported for first time Mexico. lack infecting cultivar TU carrying Co-5 gene suggests that a useful source resistance. Six produced susceptible reactions on only...
Abstract There is an increasing awareness and interest in the antioxidant behaviour potential health benefits of phenolic acids. The identification novel sources acids has been also scientific interest. Cascalote ( Caesalpinia cacalaco ) pods are known to be a good source ‘tannins’, name by which industry Mexico recognizes extract. Phenolics were determined as gallic acid equivalents g −1 . antimutagenic activity against aflatoxin B 1 activity, using two different methods, extract evaluated....
