“…Thus, to reconstruct ancestral character states in Cuscuta we analyzed the distribution of character states in-group (Welsh et al, 2010;Wright et al, 2011;Riviere et al, 2013). Adding putative outgroup Convolvulaceae and coding them with a different character state than the in-group Cuscuta (García et al, 2014) produced similar results (results not shown). Scenarios of character evolution were analyzed using the parsimony reconstruction method implemented in Mesquite 2.75 (Maddison and Maddison, 2011).…”

“…This is significant because until now stem morphology was not considered relevant for the systematics of the genus (e.g., Yuncker, 1932). Also, these stem types are important because the only available morphological characters at subgeneric levels have been a few gynoecium characters (Wright et al, 2011;García et al, 2014;Costea et al, 2015).…”

“…Character states were mapped onto the recent genus phylogeny based on rbcL and nrLSU sequences (García et al, 2014). Analysis of character polarity in Cuscuta using formal outgroup analysis is hindered by the unresolved position of Cuscuta in Convolvulaceae (Stefanović and Olmstead, 2004).…”

“…Monogynella, the first derived infrageneric lineage of Cuscuta (García et al, 2014). However, relatively similar morphologically but non-secretory multicellular structures termed "protubérances stomatifere" or stomatiferous protuberances (SPs) had been briefly observed almost eight decades earlier by Mirande (1901) on the stem epidermis of three species of subg.…”

“…Cuscuta (dodders) includes nearly 200 species of obligate stem parasites classified in four subgenera (García et al, 2014;Costea et al, 2015): Monogynella (mostly Eurasia, 15 sp. ), Pachystigma (S. Africa, five sp.…”

We present the first plastome phylogeny encompassing all 77 monocot families, estimate branch support, and infer monocot-wide divergence times and rates of species diversification. METHODS:We conducted maximum likelihood analyses of phylogeny and BAMM studies of diversification rates based on 77 plastid genes across 545 monocots and 22 outgroups. We quantified how branch support and ascertainment vary with gene number, branch length, and branch depth.KEY RESULTS: Phylogenomic analyses shift the placement of 16 families in relation to earlier studies based on four plastid genes, add seven families, date the divergence between monocots and eudicots+Ceratophyllum at 136 Mya, successfully place all mycoheterotrophic taxa examined, and support recognizing Taccaceae and Thismiaceae as separate families and Arecales and Dasypogonales as separate orders. Only 45% of interfamilial divergences occurred after the Cretaceous. Net species diversification underwent four large-scale accelerations in PACMAD-BOP Poaceae, Asparagales sister to Doryanthaceae, Orchidoideae-Epidendroideae, and Araceae sister to Lemnoideae, each associated with specific ecological/morphological shifts. Branch ascertainment and support across monocots increase with gene number and branch length, and decrease with relative branch depth. Analysis of entire plastomes in Zingiberales quantifies the importance of non-coding regions in identifying and supporting short, deep branches. CONCLUSIONS:We provide the first resolved, well-supported monocot phylogeny and timeline spanning all families, and quantify the significant contribution of plastomescale data to resolving short, deep branches. We outline a new functional model for the evolution of monocots and their diagnostic morphological traits from submersed aquatic ancestors, supported by convergent evolution of many of these traits in aquatic Hydatellaceae (Nymphaeales).

This study focused on characterizing chemically and evaluating in vitro allelopathic and bioherbicidal potential of secondary metabolites extracted from the stem of Cuscuta campestris in seed germination, early seedling growth and early plant growth of Amaranthus retroflexus and Portulaca oleracea. The combined effects of stem extract and a reduced dose of herbicide metribuzin were also examined. Plant extract contained 17 phenolic compounds and the most abundant phenols were flavonoids: quercetin, (+)-catechin, daidzin, luteolin, and rutin. The seeds of P. oleracea were less sensitive than the seeds of A.retroflexus. The seed bioassay confirmed the inhibitory effect of stem extract on germination and early growth of both weed seedlings at concentrations of 0.75 % and 1 %, and a minor inhibitory effect in the plant bioassay. On the other hand, a synergy of C. campestris stem extract and metribuzin was revealed, as their combination achieved better results in the control of both weed species. Based on obtained data C. campestris stem extract could be a potential source of naturalbased weed control molecules.
