Alternaria rot has been recently described as an emerging fungal disease of citrus causing significant damage in California groves. A survey was conducted to determine latent infections on fruits, twigs, and leaves investigate their seasonal patterns during 2019 2020. On were more associated with the stem end than stylar end, except spring when a significantly high percentage flowers (86%) had infections. Latent twigs varied markedly between years (28% 9.5% 2020), while spp. also recovered...

The center of origin peanut is located in South America, specifically southeastern Bolivia and northwestern Argentina, where its parental species are found wild habits. Even though Argentina only the seventh largest producer world (2% global production), it leading exporter edible grain crushed (e.g., flour, butter, oil) products worldwide. Peanut production was moved to more southern areas Cordoba early 1990s avoid consequences issues northern region. During this migration process, a new...

<title>Abstract</title> Peanut smut, caused by the soilborne pathogen <italic>Thecaphora frezzii</italic>, poses a significant threat to Argentina’s peanut production. Specific characteristics are presumed influence spatial pattern of this disease in field. As monocyclic disease, infections restricted pegs and pods, with no direct plant-to-plant spread. Spore dissemination occurs exclusively during harvest when infected pods release spores, which can persist soil for many years. The lack...

Abstract Peanut smut (causal agent Thecaphora frezzii ) and seasonal drought are the two main factors reducing peanut yields in Argentina. There no previous studies about effect of on occurrence. We evaluated soil water limitation symptoms greenhouse field assays. Additionally, we analysed biochemical responses plants to combined stress caused by infection experiments. found that a moderate deficit (30% water‐holding capacity) increased differentially proline reduced chlorophylls host....

Late leaf spot (LLS) caused by the Ascomycete Nothopassalora personata (N.p.) (Syn. Cercosporidium personatum) is main foliar disease of peanuts in Argentina and peanut producing areas world, causing up to 70% yield losses. The extremely slow growth this fungus culture, that takes around one month form a 1 cm colony (0.45 mm/day), lack adequate young tissues from where extract nucleic acids, have hindered genetic studies pathogen. Here, we report first genome sequence N. isolate South...

Abstract This paper presents a data-driven approach using machine learning to create model for predicting the behavior of cementation exponent "m" (it is function shape and distribution pores) in Mexican Naturally Fractured Reservoirs (NFRs), aiming reduce uncertainty reserves calculations risks on decision-making wells lacking core data information. The purpose predict with limited measurements by models trained special logs from key wells. Different authors have addressed ranges based type...

Dieback caused by Colletotrichum spp. is an emerging disease in California citrus groves. A large-scale survey with emphasis on seasonal variations of latent infections was conducted throughout orchards Fresno, Kern, and Tulare counties 2019 2020. Latent leaves twigs varied markedly between years. Isolates were obtained from asymptomatic tissue, two groups formed based colony spore morphology. The morphological further identified multigene sequence analysis using the DNA regions...

Background: Thecaphora frezii Carranza and Lindquist causes smut disease in peanut (Arachis hypogaea L.) resulting up to 35% yield losses. Fungicides have shown ineffective controlling the disease; whereas research on molecular basis of that fungicide resistance has been hindered because lack genetic information about T. frezii. The goal this work was provide fungicide-target loci frezii, including its mitochondrial genome (mitogenome) critical nuclear-encoded genes. Results: Here we...

As compression treatment offers moderate improvement, especially to recurrent venous leg ulcers (VLUs), several alternative therapies using cellular based and/or tissue-derived products (CTPs) have emerged from bovine, porcine, and equine sources. Our aim was look at the effect of a CTP in 'real-life' VLUs.This study looked complex patients with chronic, large wounds single-centre retrospective review. All were treated fetal bovine acellular dermal matrix (FBADM) for VLUs our outpatient...

Cercospora leaf spot (CLS), caused by Pseudocercospora cladosporioides, is one of the most significant foliar diseases impacting olive production. Over two consecutive years, we investigated temporal variation inoculum production and timing infections throughout year on Arbequina cultivar located in northwest Uruguay. Additionally, examined influence meteorological variables both occurrence infections. Two periods characterized substantially higher spore were identified, during late spring...

Quantification of plant disease severity is key for pathology research, particularly in the evaluation control measures. Visual estimation remains widely used, especially field. Training sessions and use standard area diagram sets (SADs) are known to enhance rater accuracy. We aimed quantify compare benefits these tools, either used alone or combination, when visually assessing peanut late leaf spot severity. designed validated SADs aid also evaluated training tool TraineR2, a web-based app...
