The reaction of IR 50, TRY 3, and IR 36 cultivars of rice to R. solani challenge, the causal agent of sheath blight, and its toxic metabolite was studied. Differential response of these cultivars to ...
2013-2014年吉林省、黑龙江省烟区首次大面积发生烟草靶斑病, 损失严重。采集吉林省柳河县、黑龙江省林口县和宾县的烟草靶斑病病叶进行分离纯化, 得到了12个菌株。将所获菌株分别与立枯丝核菌标准融合群菌株AG-2、AG-3、AG-4进行对峙培养, 结果表明:此12个菌株均与立枯丝核菌AG-3标准菌株发生融合反应, 不与其他融合群发生融合; 随机选取3个县各1个代表性菌株, 提取菌丝基因组DNA并...
Ninety eight isolates of Rhizoctonia spp. were obtained from roots of pepper (capsicum annuum L.) grown in Erzincan, Turkey during the period 2007–2008. The most prevalent multinucleate anastomosis ...
Polygalacturonase-inhibiting proteins (PGIPs) selectively inhibit polygalacturonases (PGs) secreted by invading plant pathogenic fungi. The objective of present research was to clone and introduce the...
The α-amino nitrogen (A-N) contained in the roots and crowns of sugar beet is one of the harmful non-sugars that deteriorate the quality of sugar beet roots. This research was conducted to investigate...
A new disease of wax gourd (Benincasa cerifera Savi) characterized by scab of fruit was observed in Okayama Prefecture, Japan in July 2003. Fungal isolates frequently obtained from diseased fruits o...
Damping-off was observed on seedlings of leaf mustard, Brassica juncea (L.) Czern. var. juncea (cernua group); komatsuna, Brassica campestris L. (rapifera group); mizuna, Brassica campestris L. (jap...
A new disease of carrot (Daucus carota L.) caused by Rhizoctonia solani was found in Tokushima Prefecture in 2003 and 2004. Isolates of R. solani were obtained from carrot seedlings with damping-off...
One hundred and seventeen isolates of Rhizoctonia solanihn were obtained from creeping bentgrass [Agrostis stolonifera L. var. palustris (Huds.) Farw] and Kentucky bluegrass (Poa pratensis L.) wi...
The general inadequacy of chemical fungicides to tackle Rhizoctonia solani and Fusarium oxysporum diseases in tomato has led to the search for biocontrol solutions to these maladies. Twenty-six loca...
Effect of Potassium on damping off tobacco caused by Pythium sp and Rhizoctonia solani were investigated by giving 10, 20, 30 kg/da (5, 10, 15 ppm) K2SO4 as K2O base and pathogen inoculum at the same...
通过对四川省东、南、西、北、中5个区域、55个县(市)水稻立枯丝核菌(Rhizoctonia solani)样本进行分离、纯化和菌丝融合鉴定,发现分离得到的55株立枯丝核菌菌株除了D42菌株外,其余均属于AG1IA群。还发现其中一些菌株同时能与多个群发生融合,具有桥梁菌群属性。通过离体叶片致病力鉴定发现,各菌株间致病力差异显著。进一步的RAPD聚类分析显示,在相似系数为0.941处,该55株菌株...
The efficacy of antagonistic bacteria isolates as biological agents was exploited against pathogenic fungi causing root rot and stem rot of tomato plant. Five strains of Pseudomonas fluorescences were...
