Parthenium hysterophorus, an aggressive invasive weed, poses a significant threat to biodiversity owing its remarkable adaptability. In this case study, we investigated the vegetative and reproductive phases of P. focusing on phenological growth stages based universal BBCH coding system, along with associated polyamines (PAs). Our findings revealed heightened polymorphisms in key enzymes involved PAs biosynthesis, including spermidine synthase (SPDS), spermine (SPMS), arginine decarboxylase (ADC), caffeic acid O-methyltransferase (COMT), during specific stages. Notably, SPDS exhibited elevated stem elongation flowering, while SPMS showed variability primarily flowering. Conversely, ADC COMT displayed increased leaf development flowering These insights highlight dynamic regulation PA metabolism across hysterophorus.

ABSTRACT: One of the most aggressive invasive weeds, Parthenium hysterophorus (Asteraceae) is generating serious difficulties for environment, economy, and livestock in India other parts world. The present study was conducted to isolate identify fungal pathogens from leaves weed evaluate their cultural filtrates against growth weed. Alternaria alternata isolated infected by using standard isolation techniques utilizing potato dextrose agar (PDA), during an extensive search natural enemies P. hysterophorus. After applying Koch's postulates leaf bioassay, it discovered that A. found pathogenic can be used as biocontrol agent Seed germination bioassay performed check herbicidal potential metabolites plant. pathogen's caused severe harm seeds This research aims explore biological control efficacy fungus inhibit growth.

Abstract Parthenium hysterophorus is a highly invasive weed that poses serious threat to biodiversity due its adaptability. This case study examines vegetative and reproductive phases, focusing on phenological growth stages using the universal BBCH coding system, role of polyamines (PAs) in these stages. Our research identified significant polymorphisms key enzymes involved PAs biosynthesis, including spermidine synthase (SPDS), spermine (SPMS), arginine decarboxylase (ADC), caffeic acid O-methyltransferase (COMT), during specific SPDS were more pronounced stem elongation flowering, while SPMS showed heightened variability primarily flowering. Conversely, ADC COMT exhibited increased leaf development flowering These findings underscore dynamic regulation PA metabolism across different P. hysterophorus. Drawing from findings, we can develop targeted management strategies correspond polymorphism patterns vital biosynthetic genes. Specifically, propose use broad-spectrum non-selective herbicides such as Paraquat before elongation, transitioning post-stem application selective like Bromoxynil, utilizing foliar-active translocated glyphosate formation. innovative aim optimize effectiveness reducing herbicide usage by tailoring interventions plant's metabolic state.

Abstract Invasive species are a threat to biodiversity, altering ecosystem balances by affecting native species. Parthenium hysterophorus is highly invasive weed that was introduced recently Kenya, where it rapidly spreading, particularly in the lowland areas around Lake Baringo semi-arid Rift Valley. The recent conversion of rangelands crop fields created new habitats for establishment Parthenium, while development infrastructures (roads and irrigation canals) constituted seed dispersal corridors. emergence these spatial-temporal patterns land systems may differentially affect dynamics spread its ecological economic implications. To understand determinants their effects on plant communities, we assessed floristic composition rangelands, croplands, key infrastructures, hydro-edaphic properties associated with abundance. Subsequently, related infestation changes different seasons, based 525 observation plots. We recorded 63 from 19 families. Perennial monocotyledonous dominated annual dicotyledonous were disturbed croplands roadsides. all types use except wet sodic grasslands. Hydro-edaphic conditions strongly affected abundances Parthenium. Densities relative cover highest during season, irrigated along canals (38 individuals/ m2), compacted poorly drained Gleysols Fluvisols soils shallow water tables. At high levels invasion, observed 50% reduction vegetation, differential displacement specific While several weedy co-occurred abundance C4-grasses tended be mutually exclusive. Thus, not only biomass vegetation but also reduced quality rangeland fallows ruminant grazing. With progressing system shifts towards intensified agriculture, projected wetter futures climate change East Africa, will increasingly similar environments Africa.
