“…This virus was identi ed from Syrah grapes experiencing severe decline but its association with the disease state has not been determined. GSyV-1 has since been reported from several grape growing countries including South Africa (Al Rwahnih et al, 2009;Giampetruzzi et al, 2012;Glasa et al, 2015;Oosthuizen, 2017). Phylogenetic analysis has revealed that GSyV-1 groups into two clades based on geographic origin, Europe and North America, with diversity being higher amongst the European isolates (Glasa et al, 2015).…”

The use of next generation sequencing technology has allowed for greater elucidation of viruses infecting grapevine, which number more than 85. Many of these viruses can result in disease symptoms and it is therefore vital to the industry that they be supplied with healthy plant material. This is done through grapevine certification schemes. In this study, 97 nuclear grapevine vines subjected to a virus elimination process and maintained in vector-free conditions, were subjected to total RNA sequencing using the Ion-Torrent platform to determine the presence of viruses and viroids. In total, five virus species, four viroid species, and a further putative viroid species were identified in these nuclear grapevines through NGS analysis and confirmed using RT-PCR and Sanger sequencing. Grapevine Rupestris stem pitting-associated virus was identified in six nuclear accessions, while grapevine fleck virus, grapevine Syrah virus, grapevine leafroll-associated virus 4, and grapevine Rupestris vein feathering virus were identified in one nuclear accession each. Viroids were identified in 73 of the 97 nuclear accessions, with hop stunt viroid present in 63 of the 97 samples followed by grapevine yellow speckle viroid 1, present in 52 of the 97 samples, grapevine yellow speckle viroid 2, present in 17 of the 97 samples, Australian grapevine viroid present in three of the 97 samples and grapevine hammerhead viroid-like RNA was identified in two of the 97 samples. These findings suggest that some viruses, especially GRSPaV, and viroids are recalcitrant to currently employed virus elimination techniques, and how advantageous the use of NGS is to grapevine certification schemes.

Motion events in Afrikaans: their expression by adult speakers and by children with and without language impairment

Motion events occur frequently in everyday life as people and objects constantly change their relative location to one another. Although children's descriptions of motion events resemble those of adults in their own language group from very early on (Choi and Bowermann 1991), there is increasing evidence for subtle differences as well. Young children speaking different languages seem to have some difficulty in expressing two types of spatial information in the same conceptual frame (e.g. Ochsenbauer and Hickmann 2010). In English and other satellite-framed languages such as German and Afrikaans, this task involves using a complex particle verb construction in which a directional particle (e.g. out) combines with a prepositional phrase carrying further information about the source or goal of movement (e.g. some bees came out of the tree) (Berman and Slobin 1994:161). Little is known about the development of this type of structure in satellite-framed languages such as Afrikaans. This paper examined whether (i) there are developmental differences between adults and 6-year-old Afrikaans-speaking children in the production of preposition+verb particle structures, and whether (ii) children with language impairment produce these structures in a different way than typically developing children. Target elements were preposition+verb particle structures with the particles af 'down', in 'in', uit 'out' and op 'up'. The performance of ten adults was compared to that of 30 typically developing and three language-impaired 6-year-olds. Half of the participants in the adult and typically developing groups were speakers of Mainstream Afrikaans (MA), and half were speakers of Cape Afrikaans (CA), a non-mainstream dialect. Distinct developmental differences that could not be attributed to dialectal variation, were found between 6-year-olds and adults. Children with language impairment showed less variation in their responses than their typically developing peers. Possible explanations for the findings are discussed.

“…dit changes to daar-(e.g., in dit 'in it' changes to daarin) and wat changes to waar-(e.g., op wat 'on which' changes to waarop); see Oosthuizen (2000). During MLU calculation, mergers of dit/wat/hier 'it/what/here' with a preposition were counted as one word.…”

keep the discussion succinct, a detailed description of each of the experimental tasks (which included picture selection, acceptability judgements and sentence completion) and of the analytic procedures is not given here; see Southwood (2005, 2007) for full details on the exact nature of the procedures. The results of the analysis of the participants' performance on the experimental tasks and in the language samples are presented in four subsections. First, in section 3.1, the performance of the three groups of participants across experimental tasks is compared, and the performance of some of the individual children is discussed. Then, in section 3.2, those error types related to the grammatical features number, person, case and tense in the spontaneous language samples are compared across groups. This enables one to observe general response patterns by the three groups of participants. Next, additional
