Morocco is basically an agricultural country; almost 40% of the workforce is employed in this sector. Xylella fastidiosa is a xylem-inhabiting pathogen which can infect more than 300 plant species, although most host species are symptomless. Until relatively recently, X. fastidiosa was primarily limited to North and South America, but in 2013 a widespread epidemic of olive quick decline syndrome caused by this fastidious pathogen appeared in southeastern Italy, and later several cases of X. fastidiosa outbreaks have been reported in other European countries (France, Germany and Spain). Following these recently confirmed findings of X. fastidiosa in the European Union, this bacterium has become a serious threat to the Moroccan flora. The national phytosanitary authorities have adopted several measures to prevent the introduction of X. fastidiosa into the national territory by deciding, inter alia, to suspend importation of host plant species to the bacterium from infected areas. This paper presents the phytosanitary risk of this bacterium in Morocco.

Cabbage plants showing symptoms of leaf spot were detected from various fields in the Almaty region of Kazakhstan in the winter seasons of 2015 and 2016. The disease incidences of approximately 50% were recorded in various fields visited in the Almaty region. The pathogen was aseptically isolated from the symptomatic leaves and maintained in an in vitro culture media. Morphological characteristics and sporulation of the fungus was determined under both light and electron microscopy. The extracted genomic DNA of the fungi was subjected to Polymerase Chain Reaction (PCR) using ABCsens/ABCrev and ITS1/ITS4 primers amplifying ABC transporter (Atr1) gene and the internal transcribed spacer regions, respectively. The amplified products of PCR were sequenced, aligned, blasted and compared for similarity with other species in the NCBI GenBank. The cluster analysis result showed 99% homology with related fungi retrieved from the NCBI GenBank for the ITS region. The fungal isolate was pathogenic towards twenty-two-day-old plants, namely, Brassica oleracea, Lycopersicon esculentum, Solanum melongena, and was established as the causal agent of leaf spot on these plants. This is the first record implicating A. brassicae for black leaf spot disease of cabbage in Kazakhstan.

A shift towards organic farming suggests amalgamation of organic resources against soil borne plant pathogens. The influence of metabolites of most ubiquitous Aspergillus spp., organic amendment extracts and their combined effect with Trichoderma virens were evaluated in vitro against Rhizoctonia solani. The minimum (36.1 mm) growth was attained by R. solani in co-culture with A. niger. The maximum (42.3 mm) inhibition of mycelial growth of the test organism was observed with culture filtrate of A. ochraceous followed by A. niger, A. fumigatus, A. flavus and A. terreus. Among organic amendment extractants, castor cake exhibited an additive effect on the growth of T. virens, however, the maximum (41.8 mm) suppressive effect on R. solani was observed with vermicompost. With the advance in time, the effect of organic amendment extracts increased markedly. Inhibition potential of culture filtrate mixturte of A. niger + T. virens and A. ochraceous + T. virens against R. solani was significantly higher in comparison to the other combinations.

Agrobacterium tumefaciens, a plant pathogen, is characterized by the unique feature of interkingdom DNA transfer. This soil bacterium is able to transfer a fragment of its DNA, called T-DNA (transferred DNA), to the plant cell where T-DNA is integrated into the plant genome leading to "genetic colonization" of the host. The fate of T-DNA, its processing, transfer and integration, resembles the journey of Odysseus, although our hero returns from its long trip in a slightly modified form.

The present study reports the frequent isolation of the two date palm pathogens Thielaviopsis paradoxa (de Seynes) Hohn and T. punctulata (Hennebert) Paulin, Harrington et McNew from soil of date palm plantations at Elx, south-east Spain, using dilution plate, direct soil plating or by soil treatment either with acetic acid or phenol. The two species showed a high isolation rate. T. punctulata detected from all samples (100% isolation rate), whereas, T. paradoxa showed 52% isolation rate. Total fungal colony count, ranged from 1.1×105-6 x105, CFU/g dry soil. Out of these, T. punculata comprised between 0.2-3.2% and T. paradoxa, between 0.5-4.4%. Both species were characterized by development of thick-walled aleuroconidia either singly (T. punctulata) or in chains (T. paradoxa) in addition to the phialoconidia. The widespread occurrence of the two pathogens in soil may contribute to the possibility of infection of newly transplanted offshoots of date palms.

Genomic sequence AY661558, representing a part of the ВАС contig of the Rym4/Rym5 locus conferring resistance to the barley yellow mosaic virus complex (BaMMV/BaYMV), was exploited in order to develop SSR markers for practical barley breeding. Out of 57 SSR motifs found within this sequence, primers were designed and tested for the 5 SSRs with the highest repeat length. The polymorphic SSR marker QLB1 со-segregated with rym4 and rym5 phenotypes in respective high-resolution mapping populations developed for the construction of the original ВАС contig. The primers targeted 2 sites located 756 bp and 5173 bp downstream of the translation initiation factor 4E (Hv-eIF4E). Physical linkage of the QLB1 marker to the Rym4/Rym5 locus was confirmed experimentally on Morex ВАС 519J14, a seed ВAC of Hv-eIF4E, and ВAC 801A11, which is located proximally to Hv-eIF4E. QLB1 revealed 7 alleles in a set of 100 winter barley lines and cultivars. Five alleles were found within 673 advanced breeding lines derived from applied Polish winter barley breeding programmes, which corresponds to a PIC value of 0.684. No recombinants between Rym4/5 and QLB1 were detected, suggesting that QLB1 can be used efficiently in marker-assisted selection of the Hv-eIF4E-mediated bymovirus resistance.

The interplay of plant resistance mechanisms and bacterial pathogenicity is very complex. This applies also to the interaction that takes place between the pathogen Pseudomonas syringae pv. lachrymans (Smith et Bryan) and the cucumber (Cucumis sativus L.) as its host plant. Research on P. syringae pv. lachrymans has led to the discovery of specific factors produced during pathogenesis, i.e. toxins or enzymes. Similarly, studies on cucumber have identified the specific types of plant resistance expressed, namely Systemic Acquired Resistance (SAR) or Induced Systemic Resistance (ISR). This paper presents a summary of the current state of knowledge about this particular host-pathogen interaction, with reference to general information about interactions of P. syringae pathovars with host plants.
