Abstract:
... Early blight is a common disease of Solanaceae crops worldwide. The occurrence of Alternaria spp. was studied during three epidemics on tomato in northwestern Algeria. Alternaria was detected in more than 80 % of the diseased plant samples and accounted for more than 50 % of the total fungal isolates recovered from these samples. Morphological and molecular investigations revealed that small-spore ...

Turnip mosaic virus; clones; complementary DNA; gene silencing; host plants; host range; phylogeny; viruses
Abstract:
... Turnip Mosaic Virus (TuMV) is an economically important potyvirus for which hundreds of hosts have been reported, thus making it a rather exceptional case in the genus. Several viral infectious clones have been generated over the years, which have been useful in deciphering the viral elements involved in the interactions of this virus with the host plant, such as different forms of resistance, gen ...

Abstract:
... Antifungal properties of Boerhavia diffusa L. (Nyctaginaceae) methanolic extract have been investigated against Phytophthora infestans and Phytophthora capsici, causal agents of late blight disease in tomato and pepper, respectively. The minimum inhibitory concentration of B. diffusa extract was 0.25 % for P. infestans and 0.5 % for P. capsici. The extract had fungitoxic effect on P. infestans and ...

Abstract:
... Hop stunt viroid (HSVd) infects a wide range of plants. In this study, we assembled de novo two HSVd genomes from the transcriptome of an apricot species. To examine HSVd variation in a single tree, we sequenced 70 HSVd genomes from unique apricot and plum trees and identified 11 HSVd variants. In addition, we analysed all known 572 HSVd sequences and identified 382 non-redundant HSVd variants. Ph ...

Abstract:
... By transversely cutting infected avocado plant stems and using PCR techniques on avocado leaves, two experiments were carried out to determine whether Rosellinia necatrix can invade avocado vascular tissues. We were unable to detect the pathogen in either stems or leaves in either experiment, so we concluded that R. necatrix does not invade the vascular system of the plant. Additionally, the toxin ...
