Solanum commersonii is a wild potato species that exhibits high tolerance to both biotic and abiotic stresses has been used as source of genes for introgression into cultivated potato. Among the interesting features S. resistance bacterial wilt caused by Ralstonia solanacearum, one most devastating diseases crops. In this study, we deep sequencing RNA (RNA-seq) analyze below-ground plant transcriptional responses R. solanacearum. While majority RNA-seq reads could be aligned tuberosum Group...
Hemibiotrophic plant pathogens, such as the oomycete Phytophthora infestans, employ a biphasic infection strategy, initially behaving biotrophs, where minimal symptoms are exhibited by plant, and subsequently necrotrophs, feeding on dead tissue. The regulation of this transition breadth molecular mechanisms that modulate defences not well understood, although effector proteins secreted pathogen thought to play key role. We examined transcriptional dynamics P. infestans in compatible...
Plants are often facing several stresses simultaneously. Understanding how they react and the way pathogens adapt to such combinational is poorly documented. Here, we developed an experimental system mimicking field intermittent drought on rice followed by inoculation pathogenic fungus Magnaporthe oryzae. This triggers enhancement of susceptibility that could be correlated with dampening aspects plant immunity, namely oxidative burst transcription pathogenesis-related genes. Quite...
Phytophthora infestans, the causal agent of late blight in crops Solanaceae family, is one most important plant pathogens Colombia. Not only are Solanum lycopersicum, and S. tuberosum at risk, but also several other solanaceous hosts (Physalis peruviana, betaceum, phureja, quitoense) that have recently gained importance as new Colombia may be risk. Because little known about population structure infestans Colombia, we report here phenotypic molecular characterization 97 isolates collected...
Ralstonia solanacearum is a soil and water-borne pathogen that can infect wide range of plants cause the devastating bacterial wilt disease. To successfully colonize host, R. requires type III secretion system (T3SS), which delivers effector proteins inside plant cells. HrpG central transcriptional regulator drives expression T3SS other virulence determinants. hrpG transcription highly induced upon cell contact its product also post-transcriptionally activated by metabolic signals present...
ABSTRACT. Some of the most important plant pathogens worldwide are oomycetes, and billions dollars expended annually to suppress diseases they cause. More efficient disease suppression technologies will be derived from a better understanding basic biology these organisms, but inefficient transformation currently limits molecular investigations. Of various approaches, protoplasts using polyethylene glycol/calcium chloride remains successful, frequency stable low inconsistent. Here we report...
Several breeding programs are under way to introduce resistance bacterial wilt caused by Ralstonia solanacearum in solanaceous crops. The lack of screening methods allowing easy measurement pathogen colonization and the inability detect latent (i.e., symptomless) infections major limitations when evaluating this disease plant germplasm. We describe a new method study interaction between R. potato germplasm that overcomes these restrictions. UY031 was genetically modified constitutively...
Summary The infection of plants by hemibiotrophic pathogens involves a complex and highly regulated transition from an initial biotrophic, asymptomatic stage to later necrotrophic state, characterized cell death. Little is known about how this regulated, there are conflicting views regarding the significance plant hormones jasmonic acid ( JA ) salicylic SA in different phases infection. To provide broad view process perspective, we surveyed transcriptome tomato S olanum lycopersicum during...
The objective of this research was to determine the potential use eco-friendly technologies reduce clubroot disease caused by
Bacterial wilt of potatoes –also called brown rot– is a devastating disease caused by the vascular pathogen Ralstonia solanacearum that leads to significant yield loss. As in other plant-pathogen interactions, first contacts established between bacterium and plant largely condition outcome. Here, we studied transcriptome R. UY031 early after infection two accessions wild potato Solanum commersonii showing contrasting resistance bacterial wilt. Total RNAs obtained from asymptomatic infected...
In March 2023 dieback of shoots and branches, cankers were observed in trees cacao (Theobroma cacao) plantations four municipalities the department Arauca (Arauquita, Fortul, Saravena Tame), Colombia. Arauca, main genotypes grown are FEAR 5, FTA 2, FSA 13, to a lesser extent universal clone CCN 51. The incidence diseased was greater monocultures (75-85%) than those under agroforestry systems (20-35%) for all (Figure 1a–b). Twenty samples, representing (FEAR 13 51) municipalities, taken from...
Banana, the main export fruit for Colombia, is threatened by Fusarium wilt (FWB), caused
Abstract Fusarium wilt of banana, caused by the pathogen oxysporum f. sp. cubense tropical race 4 (Foc TR4), is a threat to food security as it affects global banana industry. Control this complex due lack resistant or plantain genotypes, effective commercial fungicides, production chlamydospores, late appearance symptoms in infected plants, high adaptability diverse soil conditions and polycyclic nature disease. Currently, management strategy for Foc TR4 exclusion eradication, which costly...
Abstract Plant–virus interactions are affected by environmental conditions that determine plant vulnerability to pathogens and the population dynamics of insect vectors. We hypothesize drought enhances horizontal transmission dampening basal immunity plants, which triggers symptom expression vector manipulation. The potato yellow vein virus (PYVV) causes disease (PYVD), a re‐emerging epidemic crops in South America, is transmitted horizontally greenhouse whitefly (GWF), Trialeurodes...
Summary In order to better understand resistance P hytophthora infestans in tomato, we compared the global gene expression of susceptible M 82, with its more resistant near‐isogenic line, 6‐2 ( IL 6‐2), under field conditions using a microarray than 12 800 tomato expressed sequence tags ESTs ). Because variance was major concern, investigated likelihood false positives or negatives and demonstrated that either probability very low. The two isolines had indistinguishable constitutive...
Cape gooseberry (Physalis peruviana) is Colombia's second most exported fruit, with a market worth 37.8 million USD in 2021. Fusarium oxysporum f sp. physalis (Foph) arguably the devastating pathogen causing losses of up to 80%. Managing this disease challenging due resistance or reduced efficacy commercial fungicides and production resistant structures allowing survival soil for 30 years. Thus, new methods control are necessary. Two cape farms (organic vs. conventional) were detected free...
Identifying new sources of disease resistance and the corresponding underlying mechanisms remains very challenging, particularly in Monocots. Moreover, modification most pathways made so far is detrimental to tolerance abiotic stresses such as drought. This largely due negative cross-talks between stress signaling pathways. We have previously described role rice ZBED protein containing three Zn-finger BED domains against fungal pathogen Magnaporthe oryzae. The molecular biological functions...
Adenocarcinoma (ADC) of the lung is most frequent pathology corresponding to non-small cell cancer (NSCLC). The advent target therapy and discovery drugs that block signaling pathways related cellular events involved in progression disease have led a better prognosis cases ADC. Some targeted focuses on blockade epidermal growth factor receptor (EGFR), targeting mutations exon 19 21, with favorable clinical outcomes. However, there limited evidence respect unusual as 18 (g719x) 20 (s768). In...
Ralstonia solanacearum, the causal agent of bacterial wilt, is one most devastating diseases worldwide. In potatoes and many other commercial species such as tomato, banana, plantain, eggplant, among others, there a lack efficient strategies to control this pathogen. Therefore, using resistant cultivars might be best strategy prevent disease. However, breeding for wilt resistance challenging since latent infections pose significant limitation when evaluating disease in plant germplasm. Part...
