Parasitic plants in the Orobanchaceae cause serious agricultural problems worldwide. develop a multicellular infectious organ called haustorium after recognition of host-released signals. To understand molecular events associated with host signal perception and development, we identified differentially regulated genes expressed during early development facultative parasite Phtheirospermum japonicum using de novo assembled transcriptome customized microarray. Among that were upregulated YUC3,...
Understanding nanoparticle root uptake and root-to-shoot transport might contribute to the use of nanotechnology in plant nutrition. This study performed time resolved experiments probe Zn uptake, biotransformation physiological effects on Phaseolus vulgaris (L.). Plants roots were exposed ZnO nanoparticles (40 300 nm) dispersions ZnSO4(aq) (100 1000 mg L-1) for 48 h. Near edge X-ray absorption spectroscopy showed that 40 nm was more easily dissolved by than ZnO. It also leaves found as a...
Background Plants within the Orobanchaceae are an agriculturally important group of parasites that attack economically crops to obtain water and nutrients from their hosts. Despite agricultural importance, molecular mechanisms parasitism poorly understood. Methodology/Principal Findings We developed transient stable transformation systems for Phtheirospermum japonicum, a facultative parasitic plant in Orobanchaceae. The protocol was established by combination sonication acetosyringone...
Parasitic plants form a specialized organ, haustorium, to invade host tissues and acquire water nutrients. To understand the molecular mechanism of haustorium development, we performed forward genetics screening isolate mutants exhibiting haustorial defects in model parasitic plant Phtheirospermum japonicum. We isolated two that show prolonged sometimes aberrant meristematic activity apex, resulting severe on invasion. Whole-genome sequencing revealed respectively have point mutations...
The obligate parasitic plant witchweed (Striga hermonthica) infects major cereal crops such as sorghum, maize, and millet, is the most devastating weed pest in Africa. An understanding of nature its parasitism would contribute to development more sophisticated management methods. However, molecular genomic resources currently available for study S. hermonthica are limited.We constructed a full-length enriched cDNA library hermonthica, sequenced 37,710 clones from library, obtained 67,814...
Transporter proteins play an essential role in the uptake, trafficking and storage of metals plant tissues. The Natural Resistance-Associated Macrophage Protein (NRAMP) family plays divalent metal transport. We conducted bioinformatics approaches to identify seven NRAMP genes Phaseolus vulgaris genome, investigated their phylogenetic relation, performed transmembrane domain gene/protein structure analyses. found that gene forms two distinct groups. One group included PvNRAMP1, -6, -7 share a...
Abstract Parasitic plants that infect crops are devastating to agriculture throughout the world. These parasites develop a unique inducible organ called haustorium connects vascular systems of parasite and host establish flow water nutrients. Upon contact with host, haustorial epidermal cells at interface differentiate into specific intrusive grow endophytically toward vasculature. Following this, some re-differentiate form xylem bridge (XB) vasculatures host. Despite prominent role in...
The family Orobanchaceae includes many parasitic plant species. Parasitic plants invade host vascular tissues and form organs called haustoria, which are used to obtain water nutrients. Haustorium formation is initiated by host-derived chemicals including quinones flavonoids. Two types of quinone oxidoreductase (QR) involved in signal transduction leading haustorium formation; QR1 mediates single-electron transfers QR2 2-electron transfers. In the facultative parasite Triphysaria versicolor,...
Abstract Background Plant microbiome and its manipulation inaugurate a new era for plant biotechnology with the potential to benefit sustainable crop production. Here, we used large-scale 16S rDNA sequencing analysis unravel dynamic, structure, composition of exophytic endophytic microbial communities in two hybrid commercial cultivars sugarcane (R570 SP80–3280), cultivated genotypes ( Saccharum officinarum barberi ) one wild species spontaneum ). Results Our identified 1372 amplicon...
The review explores parasitic plants' evolutionary success and adaptability, highlighting their widespread occurrence emphasizing the role of an invasive organ called haustorium in nutrient acquisition from hosts. It discusses genetic physiological adaptations that facilitate parasitism, including horizontal gene transfer, impact environmental factors like climate change on these relationships. addresses need for further research into genomes interactions with hosts to better predict...
Parasitic plants exhibit unique adaptations, including specialized structures like haustoria and reduced organs. We analyzed genomic transcriptomic data from nine parasitic species across hemi-, holo-, endoparasitic lifestyles, uncovering distinct patterns of lncRNA abundance expression. Holoparasites exhibited the highest counts, while endoparasites displayed notable reductions. Expression analyses revealed tissue-specific patterns, with elevated activity in haustorial tissues Cuscuta....
Phtheirospermum japonicum is a facultative root parasitic plant in the Orobanchaceae family used as model plant. Facultative parasites form an invasive organ called haustorium on lateral parts of their roots. To functionally characterize abilities, quantification numbers required. However, this task quite laborious and time consuming. Here we describe efficient protocol to induce vitro by haustorium-inducing chemicals host exudate treatments P. japonicum.
