강미형 ( Mi Hyung Kang ),노태환 ( Tae Whan Noh ),이봉춘 ( Bong Choon Lee ),김상민 ( Sang Min Kim ),김형무 ( Hyung Moo Kim ) 전북대학교 농업과학기술연구소 2015 농업생명과학연구 Vol.46 No.2
Bacterial leaf blight(BLB) caused by Xanthomonas oryzae pv. oryzae(Xoo) is a major disease in Rice production. Even though the cultivation of resistant varieties to BLB has been considered one of the ways to control that disease, the problem of this strategy is that resistance can be broken because of new pathogen races being emerged against resistant varieties. Therefore, it is necessary to establish countermeasures to prevent breakdown of rice genetic resistance. Investigations on the distribution and discrimination of race and the first date of BLB incidence in rice fields were conducted as well as representative combinations of mixed-strains were selected for various resistant test to be used on IRBB germplasm for resistance to BLB. The first symptom of BLB spreading rapidly was founded on mid July in Jeonnam province and on early August in Jeonbuk province except for Buan where BLB observed on late July. The occurrence area was 2,345ha in 2012, 5,253 ha in 2013, and 11,677 ha in 2014, showing increasing in incidence over the year. K3 race was dominant from 2012 to 2014 and also showed increased dominance rate from 59.2% to 83.3% in 2012 and 2014, respectively. Most tested strains could infect IR24 and Milyang 23, but no strains could infect IRBB5 and IRBB7 known as resistant variety. Combination 2, 3, 5, 7, 8, and 9 showed strong infectivity on many genetic resources. IRBB 5 and IRBB 7 showed moderate resistance to Combination 12 and IRBB 5 and IRBB 21 showed moderate resistance to Combination 6 and 10.

신간척지 새만금 토양에서 분리한 미생물의 동정 및 이용성 검정

새로이 조성되어 농업용지로 활용될 새만금 간척지에서 토양 미생물을 분리, 동정하고 이들의 농업적 활용을 위하여 주요 식물병원균에 대한 길항력을 검정하였다. 염생식물 근권 및 체내에서 각각 82균주 및 93개 균주가 분리되었으며 주로 퉁퉁마디 근권에서 분리되었다. 분리된 균주중 총 108개의 균주가 주요 벼 병원균에 대해서 길항력을 보였다. 키다리병에는 81 균주, 잎집무늬마름병 25, 붉은곰팡이병 92, 흰잎마름병 82, 세균벼알마름병 80균주등이 길항력을 나타내었다. 이들 균주 중 길항력이 우수한 28균주를 동정해본 결과 대부분 Bacillus 속으로 나타났다. Soil microbes were isolated and identified in newly constructed reclaimed land, ‘Saemangum’ and characteristics of isolates were also examined for agricultural use. 82 and 93 isolates from rhizosphere and endophyte of native plant were collected from new reclaimed land soil. Most isolates were selected from glass wort plants and only few strains could be archived from other salt plant such as sea-blite and spergularia marina griseb. 103 isolates were appeared antibiotics ability against major pathogens include bakanae 81isolates, scab 92 isolates, bacterial leaf blight 80 isolates, sheath blight 25 isolates and grain rot 80 isolates. Among those isolates, 28 isolates which were shown strong antibiotic ability, were selected and identified Bacillus sp. by using 16S rDNA sequence and fatty acid analyze.

콩 유묘 부패를 일으키는 종자전염성 세균의 동시 검출을 위한 duplex PCR법 개발
강미형 ( Mi Hyung Kang ),노태환 ( Tae Whan Noh ),심형권 ( Hyeong Kwon Shim ),최만영 ( Man Young Choi ),이휘종 ( Hwi Jong Lee ),김형무 ( Hyung Moo Kim ) 전북대학교 농업과학기술연구소 2014 농업생명과학연구 Vol.45 No.2
콩 종자로부터 유래하여 유묘에 부패를 일으키는 콩불마름병(X. axonopodis pv. glycines, Xag)과 콩나물 무름병(Pectobacterium carotovorum subsp. carotovorum, Pcc)을 동시에 진단하는 PCR 방법을 개발하였다. 콩불마름병 진단을 위하여 X. axonopodis pv. glycines의 특이적인 유전자로 알려져 있는 glycinecin A로부터 증폭 크기가 401bp인 Xag F1와 Xag R1 프라이머를 고안하였으며, 콩나물 무름병균의 특이적인 진단을 위하여 Carotovoricine 유전자에서 227bp 크기로 증폭이 가능한 Pcc F와 Pcc R 프라이머를 고안하였다. 두 쌍의 프라이머들은 두 세균만을 증폭하고 다른 오염균들은 증폭하지 않았으며, 이들 프라이머는 Xag를 2pg까지, Pcc는 20pg까지 증폭이 가능하였다. 이들 프라이머를 이용한 검출 방법은 콩 및 유묘 부패의 원인균인 감염종자를 검정할 수 있는 방법으로 활용 가능할 것이다. Duplex PCR primers were developed for simultaneous detection of the important soybean seed pathogenic bacteria Xanthomonas axonopodis pv. glycines (Xag) and Pectobacterium carotovorum subsp. carotovorum (Pcc) which cause highly loss of yield and decreased quality of seeds in order to eliminate infected soybean seeds with these pathogen. Two specific primer pairs, Xag F1/R1 and Pcc F/R, were designed from the sequences of glycinecin A gene of Xag and carotovoricin gene of Pcc for certain identification of Xag and Pcc, respectively, in order to distinguish contaminated seeds with pathogens. A duplex PCR method for simultaneous identification and detection of Xag and Pcc was developed by amplifying both 401bp and 227bp bands. Identification of Xag and Pcc were done in the sensitivity of 2pg and 20pg, respectively. This approach can be used to exclude infected soybean seeds which act as soft rot inoculum of soybean seedling.
