CRISPR/Cas9-mediated mutagenesis of CAROTENOID CLEAVAGE DIOXYGENASE 8 in tomato provides resistance against the parasitic weed Phelipanche aegyptiaca. [PDF]

Sci Rep, 2019
Broomrapes (Phelipanche aegyptiaca and Orobanche spp.) are obligate plant parasites that cause extreme damage to crop plants. The parasite seeds have strict requirements for germination, involving preconditioning and exposure to specific chemicals ...

Striga hermonthica: A highly destructive pathogen in maize production

Environmental Challenges, 2022
Maize is a major cereal crop in sub-Saharan Africa (SSA). Subsistence farmers mostly plant it in areas where the parasite Striga hermonthica's action often reduces the harvest.

Silencing of a mannitol transport gene in Phelipanche aegyptiaca by the tobacco rattle virus system reduces the parasite germination on the host root

Plant Signaling & Behavior, 2022
Root parasitic weed Phelipanche aegyptiaca is an obligate plant parasite that causes severe damage to host crops. Agriculture crops mainly belong to the Brassicaceae, Leguminosae, Cruciferae, and Solanaceae plant families affected by this parasitic weed,

CRISPR/Cas9-Mediated Mutagenesis of Carotenoid Cleavage Dioxygenase (CCD) Genes in Sorghum Alters Strigolactone Biosynthesis and Plant Biotic Interactions

Phytobiomes Journal, 2023
Strigolactones are a group of small molecules that play critical roles in plant developmental processes and root biotic interactions. Strigolactones are agronomically important due to their role as a signal for the germination of a parasitic weed (Striga

Comparative Insights into the Microbial Diversity and Community Structure of Striga hermonthica-Infested Maize Rhizosphere

Applied Sciences, 2023
The damaging competition between crops and parasitic weeds has a negative impact on agricultural productivity; however, the impact of disturbance on the soil’s microbial community has received less attention.

Physical methods for soil disinfestation in intensive agriculture: Old methods and new approaches [PDF]

, 2010
Physical soil disinfestation is worldwide mainly applied in protected cropping systems or in small-scale intensive field crops. Continuous cropping of monocultures or different host plants for the same pest or pathogen often leads to heavily infested ...

The Potential of Arable Weeds to Reverse Invertebrate Declines and Associated Ecosystem Services in Cereal Crops [PDF]

, 2020
There is global concern that invertebrate populations are declining rapidly, particularly in agricultural habitats. Declines have been attributed to the intensification of farming systems, with many studies focussing on a lack of semi-natural habitat in ...

Trenchant microbiological-based approach for the control of Striga: Current practices and future prospects

Frontiers in Sustainable Food Systems, 2023
Striga species are obligate parasitic weeds most of which are members of the Orobanchaceae family. They are commonly associated with staple crops and constitute threats to food security, especially in Sub-Saharan Africa.

The dynamics of faba bean (Vicia faba L.) parasitism by Orobanche foetida

Phytopathologia Mediterranea, 2010
The dynamics of Orobanche foetida parasitizing faba bean are examined using Petri dish experiments. Rates of broomrape seed germination and seedling attachment to the host roots were quantified on three resistant genotypes (the Egyptian line Giza 429 ...
