title: Self-regulated strategies for writing engagement with Intermediate Phase learners

description: Ethical clearance: EFEC 6-11/2015 A self-regulation strategy development (SRSD) programme to encourage learners who struggle to self-regulate their creative writing skills. This study was conducted at a primary school in Gr 6 English medium classroom. The previous teachers of the learner participants (LPs) in this study highlighted their observations and personal experiences encountered with the learner participants (LPs). A six-month intervention programme was conducted in an attempt to improve the LPs creative writing skills. The SRSD programe taught learners self-regulation skills, to self-regulate their own learning by following the SRSD 6 stages.The SRSD stages were implemented during this 6 month period for the learners. In order to collect data an observation trial was conducted at the start of the programme followed by an interview session with three Intermediate Phase teachers, who reported on the LPs past and present creative writing progress. To monitor the efficacy that the SRSD intervention programme had on LPs creative writing skills pre-tests and post-tests were conducted. Comparative analyses were conducted at the end of the study where pre-test and post-test results were compared in a bid to ascertain whether the SRSD programme had an impact on learners creative writing skills. Results from the post-test indicated that there was an improvement in learners creative writing skills, with an increase in word count, use of adjectives, and adverbs in LPs creative writing work. LPs structured their stories better at the end of the intervention programme, LPs wrote better introductions, detailed middle parts and concluded their stories more effectively, but most important was the attitude and behaviour learners projected towards wanting to complete the work on their own. The 6 stages of the SRSD programme taught learners how to motivate themselves and stay focused on a task in order to self-regulate their learning in order to achieve creative writing independence.

title: Benchmarking Protocols for Proton Exchange Membrane Water Electrolyser

description: <strong>2020FEREC-STD-048</strong> <br> A reliable electrochemical evaluation protocols to assess the performance of the fabricated CCMs were also developed. Several operating test parameters were investigated, where it was found that a compression of 4 kN and a water flow rate of 0.1 L/min provided better temperature control and improved overall CCM performance. Furthermore, from the porous transport layer (PTL) investigation, it was found that titanium powder sintered PTLs on both the anode and cathode sides provided a better overall electrolyser cell performance at iii high current density operation. Also investigated, were the effects of different electrolyser cell conditioning and evaluation measurement parameters on the overall CCM performance and it was found that the shortest cell conditioning time of 5 min provided the lower performance while cell conditioning times of 15 min, 30 min and 45 min showed no significant differences in their results. The addition of the open circuit voltage (OCV) step and the halving of the current-voltage measurement interval time from 5 min to 2.5 min provided the best CCM performance and improved significantly the cell performance profile at 1000 mA cm-2 over time. <br> Also, the effect of pore forming additives to the anode catalyst ink on the anode catalyst layer morphology and overall PEMWE cell performance was investigated. Ammonium carbonate and ammonium bicarbonate with varying weight ratios were used as pore forming additives in the catalyst ink formulation and subsequently removed during the decal transfer process. The investigation was conducted on both Nafion 212 and Nafion 115 membranes. From the investigation of pore forming additives effects, the physical characterisation of the anode catalyst layers data showed that an increase of porosity (pore size, pore quantity and pore distribution) in the anode catalyst layer was achieved in this study. The addition of pore forming substances increased the quantity of pores in the catalyst layer. The electrochemical performance evaluation of the PEMWE cell showed that the addition of pore forming additives to the anode electrode catalyst ink formulation allowed for the reduction of iridium catalyst loading while improving the electrochemical performance. The iridium catalyst loading reduction of up to 45% was achived while improving the overall cell perfomance. Furthermore, the electrochemical evaluation tests showed that the CCMs with a high number of pores in their catalyst layers had the best catalyst utilisation compared to CCMs without pore formers.

title: Rhizospheric bacteria for use in preventing Fusarium wilt and crown root rot of tomato under natural field conditions

description: Biocontrol, an alternative to chemical control against plant pathogens, may also improve plant health and enhance fruit yield. Tomato production in open fields or greenhouses is constrained by the pathogens <i>Fusarium oxysporum</i> f. sp. <i>lycopersici</i> race 3 (<i>Fol</i> R3) and <i>F. oxysporum</i> f. sp. <i>radicis-lycopersici</i> (<i>Forl</i>). In this work, we studied the biocontrol effect of the antagonistic bacteria <i>Acinetobacter calcoaceticus Ac</i>DB3, <i>Bacillus thuringiensis Bt</i>MB9, <i>B. subtilis Bs</i>TA16, and <i>B. amyloliquefaciens Ba</i>MA26 in field trials with four tomato hybrids over two consecutive growing seasons (2019–2020 and 2020–2021). The effect of these bacteria on plant growth was also evaluated. The presence of <i>F. oxysporum</i> in field soil and/or infected plants was confirmed microbiologically. All four bacterial strains significantly suppressed the severity of Fusarium crown and root rot of tomato (FCRRT) and Fusarium wilt symptoms, as well as increased tomato yield under field conditions. Among the four strains, <i>B. subtilis Bs</i>TA16 showed the highest reduction in symptoms of Fusarium wilt (68%) and FCRRT (74%). To the best of our knowledge, this is the first report of biological control agents (BCAs) exerting antagonistic activity against both FCRRT caused by <i>Forl</i> and Fusarium wilt caused by <i>Fol</i> in tomato under field conditions.

title: <i>Diaporthe</i> species associated with symptomatic and asymptomatic infection of soybean stems in Minnesota: identity, virulence, and growth characteristics

description: Stem diseases of soybean with symptoms typical of infection by <i>Diaporthe</i> spp. are common in the Northern USA. Information is limited, however, on the characteristics of the associated pathogens. This study determined the identity and characteristics of <i>Diaporthe</i> spp. associated with symptomatic and asymptomatic soybean stems across diverse environments in Minnesota. Plants with symptoms of stem canker, pod and stem blight, and plant dieback, as well as asymptomatic plants, were sampled. Agar-based media and PCR assays were used to isolate and detect <i>Diaporthe</i> spp. from stems. The isolates were identified to species based on DNA sequencing and morphology. <i>Diaporthe</i> spp. were common in symptomatic and asymptomatic plants across all environments. Three species were detected: <i>D. longicolla, D. caulivora</i>, and <i>D. cucurbitae. Diaporthe longicolla</i> was the most widespread in distribution. <i>Diaporthe cucurbitae</i> was isolated from symptomatic soybean and confirmed to be a soybean pathogen for the first time. Only <i>D. longicolla</i> was detected in asymptomatic plants. While all isolates were pathogenic to soybean, virulence differed among isolates, and cultivars differed in susceptibility. Temperatures of 25°C and 32°C differentially influenced the growth of <i>D. longicolla</i> and <i>D. caulivora</i>. All isolates were sensitive to pyraclostrobin and tebuconazol. The results advance our understanding of the <i>Diaporthe</i> species associated with different soybean stem diseases, as well as their characteristics and management.

title: Response of the legume <i>Macrotyloma axillare</i> ‘Java’ to different inoculum levels of <i>Meloidogyne javanica</i> and defence responses

description: This study aimed to examine the relationship between <i>Macrotyloma axillare</i> ‘Java’ and <i>Meloidogyne javanica</i> at different levels of nematode inoculum, and to assess the activity of plant defence enzymes in the presence of nematodes. In Experiment 1, ‘Java’ and soybean (control) were inoculated with 300 to 8000 eggs + second-stage juveniles (J2) of <i>M. javanica</i> in two different periods (Trials 1 and 2). To confirm the results, a third trial was conducted using 1000 to 4000 eggs + J2 per plant. In Experiment 2, β-1,3-glucanase (GLU), phenylalanine ammonia-lyase (PAL), peroxidase (POX), and polyphenol oxidase (PPO) activities were measured in non-inoculated plants and in plants inoculated with 2000 eggs + J2. ‘Java’ presented a reproduction factor (RF) &lt; 1 at all inoculum levels in Trial 1 (RF of 0.17–0.78) and at 2000, 3000, and 6000 eggs + J2 in Trial 2 (RF of 0.47, 0.86, and 0.59, respectively). In Trial 3, ‘Java’ showed a RF &lt; 1 at all inoculum levels except for 3000 eggs + J2 (RF = 1.1). There was no difference in ‘Java’ vegetative variables in relation to inoculum levels in any experiment. In Experiment 2, inoculated plants showed increased GLU, PAL, POX, and PPO activities, when compared with non-inoculated plants. ‘Java’ appears to be moderately resistant to <i>M. javanica</i>, reducing nematode reproduction at different inoculum levels. The plant exhibits increased GLU, PAL, POX, and PPO activities in the presence of <i>M. javanica</i>.

title: Genetic structure and genome-wide association study of a genomic panel of two-row, spring barley (<i>Hordeum vulgare</i> L.) with differential reaction to Fusarium head blight (<i>Fusarium graminearum</i> Schwabe) and deoxynivalenol production

description: Fusarium head blight (FHB), primarily incited by <i>Fusarium graminearum</i> Schwabe, is the most devastating disease of barley (<i>Hordeum vulgare</i> L.) in Canada. Contaminated grains are unsuitable for use as livestock feed or by the malting industry, primarily due to contamination by mycotoxins such as deoxynivalenol (DON). Reducing DON content has been a long-term goal of barley breeders; however, the complex genetics of resistance and laborious testing required have made it difficult to develop resistant cultivars. An Illumina 50 K SNP beadchip was used to genotype a diverse collection (n = 400) of two-row barley genotypes, selected primarily from North American-breeding programs. This genomic panel was phenotyped in three environments in Manitoba, Canada, over two growing seasons. Genotypes were evaluated for heading date, height, FHB score, and DON content. A genome-wide association study (GWAS) was carried out using a mixed linear model (<i>MLM: Q</i> + <i>K</i>) accounting for population structure (<i>Q</i>) and kinship (<i>K</i>) as covariates. This study characterized the population structure of two-row barley germplasm important to North American-breeding programs. Significant marker-trait associations were identified on all chromosomes for FHB, and on all chromosomesexcept 1 H and 6 H for DON content. Individual marker effects were small, explaining only up to 5% of the phenotypic variation. Genes within genomic regions that were associated with FHB-related traits displayed multiple functions linked with disease resistance. While numerous minor, marker-trait associations were identified, phenotypic evaluations are still the best predictors of these traits, despite their time-consuming nature and dependenceon environmental conditions.
