Publication: Trans-species microRNA loci in the parasitic plant Cuscuta campestris have a U6-like snRNA promoter

Cuscuta campestris haustorium

Cuscuta campestris produces many unique microRNAs only at the haustorial interface with hosts. Our previously published work showed that these interface-induced microRNAs can target host messenger RNAs (mRNAs). The targeted host mRNAs generally function in immune responses, vascular system functions, or hormone signal transduction. Our overall hypothesis is that the Cuscuta interface-induced microRNAs act in […]

Role of Strigolactones in the Host-Specificity of Broomrapes and Witchweeds

Root parasitic plants of the Orobanchaceae, broomrapes and witchweeds, pose a severe problem to agriculture in Europe, Asia, and especially Africa. These parasites are totally dependent on their host for survival, and therefore their germination is tightly regulated by host presence. Indeed, their seeds remain dormant in the soil until a host root is detected […]

Resource availability and parasitism intensity influence the response of soybean to the parasitic plant Cuscuta australis

1

Introduction: Parasitic plants can damage crop plants and consequently cause yield losses and thus threaten food security. Resource availability (e.g., phosphorus, water) has an important role in the response of crop plants to biotic attacks. However, how the growth of crop plants under parasitism are affected by environmental resource fluctuation is poorly understood. Methods: We […]

Transcriptome analysis reveals defense-related genes and pathways during dodder (Cuscuta australis) parasitism on white clover (Trifolium repens)

1

Dodders (Cuscuta australis R. Br.) are holo-parasitic stem angiosperms with an extensive host range that have significant ecological and economic potential impact on the ecosystem and the agricultural system. However, how the host plant responds to this biotic stress remains mostly unexplored. To identify the defense-related genes and the pathways in white clover (Trifolium repens […]

How the mistletoe infects a host tree?

A research that talks about the molecular infective process of the Psittacanthus calyculathus mistletoe on mesquite trees. Lignocellulolytic enzymes, proteins, phytohormones and proteases involved in the infectious process were analyzed.

Phenotypic diversity in pre- and post-attachment resistance to Striga hermonthica in a core collection of rice germplasms

1-94828591

In sub‐Saharan Africa, rice is the third‐largest source of food energy, with a rising demand due to population growth and changes in eating habits. The expansion of rice cultivation by converting fallow, maize, and sorghum fields into rainfed rice fields is one method that will help to close the gap between rice demand and production […]

Cuscuta species: Model organisms for haustorium development in stem holoparasitic plants

fpls-13-1086384-g001H-03dda9fb

Parasitic plants are notorious for causing serious agricultural losses in many countries. Specialized intrusive organs, haustoria, confer on parasitic plants the ability to acquire water and nutrients from their host plants. Investigating the mechanism involved in haustorium development not only reveals the fascinating mystery of how autotrophic plants evolved parasitism but also provides the foundation […]

Dodder parasitism limited the effect of arbuscular mycorrhizal fungi on litter decomposition

QQ截图20230720143324

Effects from parasitism and parasitic litter input can affect the decomposition of litter, but the mechanism is unclear. We hypothesized that the decomposition of litter produced by the holoparasite Cuscuta australis is promoted more strongly by arbuscular mycorrhizal fungi (AMF) than the litter of its host Bidens pilosa and that parasitism by C. australis can […]
