Sclerospora graminicola pathogen is the most important biotic production constraints of pearl millet in India, Africa and other parts of the world. We report a de novo whole genome assembly and analysis of pathotype 1, one of the most virulent pathotypes of S. graminicola from India. The draft genome assembly contained 299,901,251 bp with 65,404 genes. This study may help understand the evoluti...
Pathogenic fungi drastically affect plant health and cause significant losses in crop yield and quality. In spite of their impact, little is known about the carbon sources used by these fungi in planta and about the fungal transporters importing sugars from the plant-fungus interface. Here, we report on the identification and characterization of MELIBIOSE TRANSPORTER1 (MBT1) from the hemibiotro...
The relative DNA content of hypodermal nuclei of preparasitic, 2nd-stage larvae was determined cytophotometrically in 19 populations belonging to 13 species of Meloidogyne, Heterodera and Meloidodera. In Meloidogyne hapla, M. arenaria, M. incognita and M. javanica, total DNA content per nucleus is proportional to their chromosome number, indicating that chromosomal forms with high chromosome nu...
Cotransformation of Glomerella graminicola was achieved with the G. graminicola genes TUB1R1 (encoding a beta-tubulin which confers resistance to the fungicide benomyl) and PYR1 (encoding orotate phosphoribosyl transferase, which confers pyrimidine prototrophy). The cotransformation frequency was about 30% when selection was for pyrimidine prototrophy (Pyr) and 87% when selection was for benomy...
Meloidogyne graminicola is an economic yield loss causing major pest of rice globally. For managing this pest, biological control practices act as alternate strategy, it the most effective and economic. Plant growth promoting rhizospheric bacteria (PGPR) are significant because they benefit plants both directly indirectly by enhancing plant provides long lasting antagonistic effects against par...
Potassium (K), an important nutrient element, can improve the stress resistance/tolerance of crops. The application K in resisting plant-parasitic nematodes shows that treatment reduce occurrence nematode diseases and increase crop yield. However, data on K2SO4 induced rice resistance against root-knot Meloidogyne graminicola are still lacking. In this work, reduced galls plants delayed develop...
بهطور کلی ژنهای مرجع در تجزیه و تحلیلهای بیان ژن، از بین ژنهای خانهدار انتخاب میشوند، اما تغییرات دیده شده در مقدار بیان مانع اساسی برای استفاده بهینه از آنهاست. از آنجا که بیان هیچ تک ژنی در شرایط مختلف و سلولهای متفاوت ثابت نیست، معرفی و اعتبارسنجی ژنهای مرجع بسیار مهم است. در این تحقیق مناسب بودن هفت ژن خانهدار گندم برای نرمالسازی بیان mRNA در برگ این گیاه در هنگام آلودگی به قارچ ...
Many plant pathogenic fungi, such as the cereal pathogen Colletotrichum graminicola, differentiate highly specialized infection structures called appressoria, which send a penetration peg into the underlying plant cell. Appressoria have been shown to generate enormous turgor pressure, but direct evidence for mechanical infection of plants by fungi is lacking. A microscopic method was developed ...
An F(1) mapping population of the septoria tritici blotch pathogen of wheat, Mycosphaerella graminicola, was generated by crossing the two Dutch field isolates IPO323 and IPO94269. AFLP and RAPD marker data sets were combined to produce a high-density genetic linkage map. The final map contained 223 AFLP and 57 RAPD markers, plus the biological traits mating type and avirulence, in 23 linkage g...
ABSTRACT The selective effect of quantitative host resistance on pathogen aggressiveness is poorly understood. Because two previous experiments with a small number of bread wheat cultivars and isolates of Mycosphaerella graminicola had indicated that more susceptible hosts selected for more aggressive isolates, we conducted a larger experiment to test that hypothesis. In each of 2 years, six cu...
