Summary: Common scab is a significant potato disease caused by Streptomyces spp. This study identified a strain of Streptomyces from scabby potatoes in Heilongjiang Province, China, which has the ability to cause typical scab lesions and is highly similar to a strain from Korea. Additionally, this strain was detected in scabby potato samples collected in Heilongjiang Province.

Summary: This study found that the response of potatoes to the phytotoxin thaxtomin A (TA), produced by the bacteria Streptomyces scabiei, does not correlate with potato sensitivity to common scab. TA treatment leads to browning of potato tuber flesh, which is likely due to the accumulation of phenolic compounds. These phenolics may play a role in protecting potatoes against the disease.

Summary: In this study, the genomes of 14 prevalent scab-causing Streptomyces spp. from Prince Edward Island, a significant Canadian potato production area, were analyzed. The virulence factors of these strains were compared, revealing novel findings challenging previous assumptions on Streptomyces' virulence. The study suggests that other factors, yet to be characterized, may play a key role in the pathogenicity of these scab-causing Streptomyces strains.

Summary: Fourteen strains of Streptomyces isolated from scab lesions on potato are described as members of a novel species based on genetic distance, morphological observation and biochemical analyses. The strains have unique characteristics and susceptibilities to certain antibiotics. Although their 16S rRNA gene sequences are identical to other Streptomyces species, whole-genome average nucleotide identity and multi-locus sequence analysis confirm that they belong to a new species.

Summary: This study aimed to determine whether surfactin is the main compound active against Streptomyces scabies in potato common scab. The results showed that the srf gene cluster of Bacillus amyloliquefaciens Ba01 is responsible for the secretion of surfactin and inhibition of S. scabies. Knocking out the srf gene cluster significantly decreased the swarming ability, biofilm formation, enzyme activity, and inhibitory effect of Ba01 on S. scabies.

Summary: Potato common scab (CS) and peanut pod wart diseases cause significant economic losses in Israel. A study on the Streptomyces spp. population identified seven species among the isolates collected from potato tubers and peanut pods. Pathogenic Streptomyces were detected in soil samples from potato fields with CS history. Imported potato seed lots from Europe were found to be contaminated with CS symptoms.

Summary: This study characterized the genetic and phenotypic diversity of pathogenic Streptomyces spp. causing Common scab (CS) in Prince Edward Island, Canada. Analysis revealed 14 distinct genetic groups, with varying levels of virulence. The most virulent genetic groups seemed to dominate the pathogenic Streptomyces spp. populations in each field, highlighting the importance of understanding population dynamics for managing this potato disease efficiently.

Summary: This study investigated the status of common scab and disease occurrence in potato growing areas in Pakistan. The highest incidence of common scab was found in Sahiwal. The disease frequency in different potato varieties was also examined, with 'Kuroda' and 'Santi' being highly susceptible to common scab, while 'Diamant' and 'Cardinal' showed medium susceptibility and 'Lady Rosita' and 'Asterix' exhibited high resistance. The study suggests the cultivation of resistant and moderately susceptible varieties and the development of new resistant cultivars.

Summary: This study revealed that tryptophan can induce resistance against potato common scab by regulating metabolic processes, stimulus response, and biological regulation. The expression patterns of candidate genes involved in salicylic acid and jasmonic acid/ethylene pathways were also analyzed, showing that tryptophan can induce systemic acquired resistance and induced systemic resistance pathways to enhance potato's resistance against common scab.

Summary: Potato, as the main staple food for 1.3 billion people worldwide, is gaining increasing global recognition due to its widespread acceptance. However, the sustainable production of potatoes faces challenges such as diseases, pests, and climate change. Common scab, caused by multiple strain of the phytopathogenic streptomyces, is a major threat to potato crops due to its ability to secrete phytotoxins and spread through soil. Despite extensive research, an effective solution to this global threat has not yet been found, highlighting the importance of understanding the host-pathogen interaction.

Summary: This article discusses the importance of bacterial pathogens utilizing mART enzymes as virulence factors, focusing mainly on research in human and plant pathogens. In human pathogens, there have been numerous studies showing the key role of mARTs in suppressing host immune responses. In contrast, research on mART enzymes as virulence factors in plant pathogens is relatively new.
