“…This implies that different pathotypes responded differently in terms of their ability to infect under different temperature regimes. Increased infection as the temperature rises had been observed by other researchers (Kosaida, 2008). This could also indicate that temperature range used had affected the spore viability thus impacting significantly on pathogenicity of the fungi (Agrios, 2005).…”

“…Additionally, a number of authors have reported different and conflicting temperature ranges for optimum infection by the fungus. For instance, the highest infection by P. teres f. teres has been observed under 10 hours of photoperiod at 25 o C (Kosiada, 2008). In Kenya, areas with as low as 6 -14 o C and as high as 22 -26 o C (Mau Narok) temperature ranges and a minimum of 12 hours photoperiod in high altitude zones have recorded high disease levels (Owino et al, 2014).…”

Mixed information on the appropriate temperature required by P. teres f. teres pathotypes for successful infection of barley is one of the bottlenecks especially on sensitive studies on virulence and pathogenicity that require specific conditions. The study aimed at determining how morphologically diverse species of P. teres respond to different temperature regimes at different time interval. Infected leaf tissues were collected from major barley growing zones representing high, medium and low altitudes. Isolation was done from these tissues in pathology laboratory and three morphologically distinct pathotypes from high and low altitudes selected for virulence and pathogenicity assessment. Susceptible barley variety (Sabini) was then planted in split-split plot experimental arrangement in randomized complete block design with three replicates. Severity data was scored on a 1-5 scale, transformed as log 10 (x +1) then subjected to analysis of variance on Genstat statistical software release 14.1 at 5% level of significance. A significant difference between the means for isolates and temperature ranges was separated using contrast, comparison. Isolates, temperature regimes and all the interactions had significant effect on severity (p < 0.05). This indicates that each of the factors had additive effect on the disease level. However, time interval alone was not significant (p > 0.05). The 'Chep 3' isolate from medium altitude was most virulent at 30-40 o C while the 'Mau 6' from high altitude was the most sensitive to temperature and time variation, indicating that these pathotypes are could be adapted to specific zones. Therefore, temperature plays vital role in virulence and pathogenicity but this also depends on time of exposure and strain of the pathogen.

“…Baudin plants were grown to the third leaf stage (Zadok's growth stage Z13.3/20) (Lancashire et al 1991). Inoculation was performed using a method similar to that described by Kosiada (2008). Briefly, seedling trays were sprayed with 30 ml of either spore suspension or control solution using a spray bottle and allowed to dry for 30 min.…”

Analysis of apoplastic proteins expressed during net form net blotch of barley

et al. 2020

The net form net blotch (NFNB) is a significant disease of barley. Its causal agent, Pyrenophora teres f. teres (PTT), has an important economic impact on yield and grain quality globally. However, the molecular interaction between PTT and barley is not fully understood. The plant-pathogen encounter comprises the secretion of diverse molecules involved in plant defence, including pathogenicity-related proteins, and fungal attack, such as proteinaceous toxins called effectors. The forefront of the molecular crosstalk between plant and fungus is the space between plant cells or apoplast. To explore the suitability of studying apoplastic proteins to assist understanding the host-pathogen interaction, a mass spectrometry-based proteomics technique was used to profile apoplastic protein differences in control and NFNB-infected leaves in a susceptible cultivar. The analysis revealed 1130 barley proteins, of which 140 were found to be significantly differentially expressed. This paper presents an overview of the major protein changes induced in the barley apoplast and discusses the involvement of individual proteins in defence and disease development. Our results suggest that the fungus may be hijacking defence signalling pathways. This investigation provides the first in vivo proteomics data for a NFNB-barley interaction, setting a background for further studies.
