The Effect of UG in the L2 Acquisition of Long-Distance Binding
JunMo Cho 한국생성문법학회 2006 생성문법연구 Vol.16 No.2
This study deals with two theoretical issues relevant to binding, namely argument/adjunct distinction and the finiteness domain effect, by investigating the interlanguage of 44 Korean native speakers learning English. Various types of LD binding were tested to see the effects of the contrasts between argument and adjunct anaphors and between finite and non-finite clause boundaries. The results show that Korean speakers allow LD binding significantly more freely when the anaphor is in an adjunct position, and they also do so when binding takes place over a non-finite clause. These results are rather surprising because in Korean the argument/adjunct distinction does not play a role for binding purposes, and because neither Korean nor English has the finiteness domain effect for LD binding. Accordingly, the result of this experimental study supports the view that interlanguage is UG-constrained.

Mutations at V421M and L1029H in the hscp sodium channel gene are known to contribute to knockdown resistance (kdr) in the Woodrow, Dalzell, and PTJ strains of H. virescens (tobacco budworm) from the cotton fields of South Carolina, USA. In the IS6 region of the sodium channel gene, the frequencies of the mutant allele methionine in the Woodrow and Dalzell strains were 0.07 and 0.1, respectively. For the IIS6 region, the frequencies of the mutant allele histidine in Woodrow and Dalzell strains were 0.175 and 0.263, respectively. In the PTJ strain, the frequencies of methionine and histidine alleles were 0 and 0.1, respectively. The Hpy3 allele, which is strongly linked to the histidine mutant allele, was also found in Woodrow and Dalzell strains. In addition, we found a new allele, which is one nucleotide different from Hpy3, called Hpy3-1, and found that it is also linked to histidine.

From 1996 to 1999, potato-growing areas in Korea were surveyed for identification and distribution of potato scab pathogens. Potato scab was widely distributed in the mass cultivation areas, especially in Jeju island, southern areas of Chonnam and Gyounggi provinces, and the alpine area of Gangwon province. Jeju island was the most affected area by this disease. A total of 55 Streptomyces strains were isolated from potato scab lesions, among which 40 strains were pathogenic on progeny tubers. Among the pathogenic strains, 21 strains were identified as previously described S. scabies, 7 strains as S. turgidiscabies, and 5 strains as S. acidiscabies, while 7 strains were observed as having distinct phenotypic properties. These strains were classified into six distinct clusters based on phenotypic characteristics and selected representative strains for each cluster. S. scabies (S33) had grey spores in a spiral chain. Meanwhile, S. turgidiscabies (S27) had grey spores, S. acidiscabies (S71) had white spores, S. luridiscabiei (S63) had yellow-white spores, S. puniciscabiei (S77) had purple-red spores, and S. niveiscabiei (S78) had thin and compact white spores, all in a rectiflexuous chain. Pathogenicity was determined by the production of thaxtomin A and homologs of nec1 and ORFtnp genes. In TLC, representative strains S33, S27, S71, S63, S77, and S78 produced a yellow band that co-migrated with the authentic thaxtomin A. However, thaxtomin A was not detected in chloroform extracts from oatmeal broth culture and slice tuber tissue of S. luridiscabiei (S63) and S. puniciscabiei (S77) by HPLC analysis. In addition, no homologs of nec1 and ORFtnp genes in S. acidiscabies (S71), S. luridiscabiei (S63), S. puniciscabiei (S77), and S. niveiscabiei (S78) were detected by PCR and Southern hybridization analysis.
