Abstract The rice (Oryza sativa) gene xa13 is a recessive resistance allele of Os-8N3, member the NODULIN3 (N3) family, located on chromosome 8. Os-8N3 susceptibility (S) for Xanthomonas oryzae pv oryzae, causal agent bacterial blight, and defeated by strains pathogen producing any one type III effectors AvrXa7, PthXo2, or PthXo3, which are all members transcription activator-like (TAL) effector family. Both AvrXa7 PthXo3 induce expression second N3 here named Os-11N3. Insertional...
Eight diverse sorghum (Sorghum bicolor L. Moench) accessions were subjected to short-read genome sequencing characterize the distribution of single-nucleotide polymorphisms (SNPs). Two strategies used for DNA library preparation. Missing SNP genotype data imputed by local haplotype comparison. The effect type and genomic diversity on discovery imputation are evaluated. Alignment eight equivalents (6 Gb) public reference revealed 283,000 SNPs at ≥82% confirmation probability. Sequencing from...
Abstract Mutations in disease susceptibility (S) genes, here referred to as recessive resistance have promise for providing broad durable crop species. However, few genes been characterized. Here, we show that the broadly effective gene xa5 ,for bacterial blight of rice ( Oryza sativa ), is dependent on effector present pathogen. Specifically, effectiveness preventing by strains Xanthomonas oryzae pv. major transcription activation‐like TAL ) and correlates with reduced expression cognate S...
Abstract Bud rot, caused by Phytophthora palmivora, is one of the major lethal diseases coconut palm. It a sporadic disease but can assume epidemic proportions occasionally. There high risk involved in carrying out studies plant–pathogen interactions through field trials, especially crop like coconut. We have developed an vitro leaf assay, which would enable easy and close monitoring occurring between P. palmivora during course infection recreating process laboratory. Spindle leaves from...
<title>Abstract</title> Background The bud rot pathogen <italic>Phytophthora palmivora</italic> poses a significant threat to coconut production worldwide. Effective management strategies against this devastating are lacking due the absence of resistant cultivars and limited knowledge about its pathogenicity mechanisms. To address this, we conducted dual RNA-seq analyses at three time points (12, 24, 36 hours post-infection) during initial progression disease, using standardized in vitro...
The coconut rhinoceros beetle (CRB), Oryctes Linn. (Coleoptera: Scarabaeidae), is one of the major pests causing severe yield losses. adult beetles feed on unopened spear leaf (resulting in typical 'V'-shaped cuts), spathes, inflorescence, and tender nut leading to stunted palm growth reduction. Moreover, these damages serve as predisposing factors entry other fatal enemies palms, viz., red weevil bud rot disease, loss high 10%. CRB attacks juvenile palms through collar region, affecting...
Oryctes rhinoceros nudivirus (OrNV) is a double-stranded DNA virus known to cause lethal infections the larval and adult stages of rhinoceros, beetle, major pest coconut oil palm. However, in recent times, some beetle populations have been reported develop resistance against virus, affecting efficacy OrNV as biocontrol agent. Thus, there an urgent need elucidate underlying mechanism viral host insect. Among diverse group small RNAs, microRNAs (miRNAs) are single-stranded endogenous...
Bacterial blight of pomegranate caused by Xanthomonas citri pv. punicae (Xcp) is a major constraint on production in India. Multiple incidences 60-80% yield losses have been reported from growing areas. The molecular mechanism susceptibility to this disease yet be unraveled. A complete genome sequence required identify the pathogen's virulence factors. available genomes pathogen are not complete. We used PacBio platform obtain long reads and assembled Xcp-119 it consists 15 contigs with an...
