Among the group of ubiquitous soil inhabiting fungi, Trichoderma species are of considerable commercial importance due to their ability to suppress many plant pathogenic fungi. They have been widely studied and employed for management of root and seedling diseases of many crops since decades. In recent years they are also being utilized for minimising diseases of foliar plant parts, especially ...

The gene-for-gene hypothesis states that for each gene controlling resistance in the host, there is a corresponding, specific gene controlling avirulence in the pathogen. Allelic series of the cereal mildew resistance genes Pm3 and Mla provide an excellent system for genetic and molecular analysis of resistance specificity. Despite this opportunity for molecular research, avirulence genes in mi...

Rust diseases caused by fungi of the order Pucciniales afflict a wide range of plants, including cereals, legumes, ornamentals, and fruit trees, and pose a serious threat to cropping systems and global food security. The obligate parasitic lifestyle of these fungi and their complex life cycles, often involving alternate hosts for the sexual and asexual stages, also make this group of pathogens ...

Current and emerging plant diseases caused by obligate parasitic microbes such as rusts, downy mildews, and powdery mildews threaten worldwide crop production and food safety. These obligate parasites are typically unculturable in the laboratory, posing technical challenges to characterize them at the genetic and genomic level. Here we have developed a data analysis pipeline integrating several...

Introduction The fungicidal properties of morpholines with large ring N-substituents was first reported in 1965 [ l ] and since then several (Fig. 1) have been marketed for the control of plant pathogenic fungi. Dodemorph, tridemorph, aldimorph and fenpropimorph are used to control powdery mildews and have both protective and eradicant properties. They are systemic in action, being absorbed thr...

Colletotrichum species infect several economically important crop plants. To establish a compatible parasitic interaction, a specialized infection cell, the melanized appressorium, is differentiated on the cuticle of the host. After penetration, an infection vesicle and primary hyphae are formed. These structures do not kill the host cell and show some similarities with haustoria formed by powd...
