Pontederiaceae
A plant family of the order Liliales, subclass Liliidae, class Liliopsida (monocotyledons). Most species are perennials, native primarily to tropical America. They have creeping rootstocks, fibrous roots, and leaves in clusters at the base of the plant or borne on branched stems. The fruit is a capsule containing many seeds, or a one-seeded winged structure.
Rooting phylogenetic trees with distant outgroups: a case study from the commelinoid monocots. (1/9)
Phylogenetic rooting experiments demonstrate that two chloroplast genes from commelinoid monocot taxa that represent the closest living relatives of the pickerelweed family, Pontederiaceae, retain measurable signals regarding the position of that family's root. The rooting preferences of the chloroplast sequences were compared with those for artificial sequences that correspond to outgroups so divergent that their signal has been lost completely. These random sequences prefer the three longest branches in the unrooted ingroup topology and do not preferentially root on the branches favored by real outgroup sequences. However, the rooting behavior of the artificial sequences is not a simple function of branch length. The random outgroups preferentially root on long terminal ingroup branches, but many ingroup branches comparable in length to those favored by random sequences attract no or few hits. Nonterminal ingroup branches are generally avoided, regardless of their length. Comparisons of the ease of forcing sequences onto suboptimal roots indicate that real outgroups require a substantially greater rooting penalty than random outgroups for around half of the least-parsimonious candidate roots. Although this supports the existence of nonrandomized signal in the real outgroups, it also indicates that there is little power to choose among the optimal and nearly optimal rooting possibilities. A likelihood-based test rejects the hypothesis that all rootings of the subtree using real outgroup sequences are equally good explanations of the data and also eliminates around half of the least optimal candidate roots. Adding genes or outgroups can improve the ability to discriminate among different root locations. Rooting discriminatory power is shown to be stronger, in general, for more closely related outgroups and is highly correlated among different real outgroups, genes, and optimality criteria. (+info)Systematic significance of cell inclusions in Haemodoraceae and allied families: silica bodies and tapetal raphides. (2/9)
This paper presents the first record of silica deposits in tissues of Haemodoraceae and adds new records of tapetal raphides in this family. Within the order Commelinales, silica is present in leaves of three families (Hanguanacaeae, Haemodoraceae and Commelinaceae), but entirely absent from the other two (Pontederiaceae and Philydraceae). Presence or absence of characteristic cell inclusions may have systematic potential in commelinid monocotyledons, although the existing topology indicates de novo gains and losses in individual families. Silica sand was observed in leaves of five out of nine genera examined of Haemodoraceae, predominantly in vascular bundle sheath cells and epidermal cells. Within Haemodoraceae, silica is limited to subfamily Conostylidoideae. The occurrence of silica in Phlebocarya supports an earlier transfer of this genus from Haemodoroideae to Conostylidoideae. The presence of raphides (calcium oxalate crystals) in the anther tapetum represents a rare character, only reported in a few monocot families of the order Commelinales, and possibly representing a mechanism for regulation of cytoplasmic free calcium levels. Tapetal raphides were observed here in Anigozanthus and Conostylis (both Haemodoraceae), and Tradescantia (Commelinaceae), thus supplementing two earlier records in Haemodoraceae, Philydraceae and Commelinaceae. (+info)Genetic control of albinism in pickerelweed (Pontederia cordata L.). (3/9)
Pickerelweed (Pontederia cordata L.) is a diploid (2n = 2x = 16) perennial aquaphyte. Preliminary studies revealed that a group of nonalbino pickerelweed plants maintained for breeding and inheritance studies regularly produced albino seedlings. The objective of this experiment was to determine the number of loci, number of alleles, and gene action controlling albinism in pickerelweed. Five nonalbino parental lines were used in this experiment to create S(1) and F(1) populations. F(2) populations were produced through self-pollination of F(1) plants. Evaluation of S(1), F(1), and F(2) generations allowed us to identify a single diallelic locus controlling albinism in these populations of pickerelweed, with albinism completely recessive to normal green leaf production. We propose that this locus be named albino with alleles A and a. (+info)Nucleotide substitutions in the acetolactate synthase genes of sulfonylurea-resistant biotypes of Monochoria vaginalis (Pontederiaceae). (4/9)
Some point mutations in acetolactate synthase (ALS) confer resistance to ALS-inhibiting herbicides in weeds. To clarify the evolution of the herbicide resistance of Monochoria vaginalis, a weed in rice fields in Japan, the nucleotide sequences of four genes encoding ALS were surveyed in five sulfonylurea-resistant (SU-R) and five sulfonylurea-susceptible (SU-S) biotypes. In the ALS1 gene, two SU-R biotypes showed nucleotide substitutions changing Pro197 to Ser and Leu, respectively. In a different gene, ALS3, three other SU-R biotypes showed either of the two nonsynonymous nucleotide substitutions seen in ALS1. Only two biotypes geographically located distantly from each other shared the same mutation conferring SU resistance in the same gene. These patterns of nucleotide substitutions indicate that the SU-R phenotype was acquired independently by different biotypes. Nucleotide diversity values of the genes showing SU-R mutations were higher than those of ALS2 lacking any SU-R mutation and of a putative pseudogene, ALS4. This result suggests that the maintenance of nucleotide variability within target genes provides an opportunity for the evolution of SU-R phenotypes by herbicide-driven selection for mutations conferring resistance. (+info)Inheritance of flower color in pickerelweed (Pontederia cordata L.). (5/9)
Pickerelweed (Pontederia cordata L.) is a diploid (2n = 2x = 16), erect, emergent, herbaceous aquatic perennial. The showy inflorescences of pickerelweed make this species a prime candidate for inclusion in water gardens and aquascapes. The objective of this experiment was to determine the number of loci, number of alleles, and gene action controlling flower color (blue vs. white) in pickerelweed. Two blue-flowered and one white-flowered parental lines were used in this experiment to create S(1) and F(1) populations. F(2) populations were produced through self-pollination of F(1) plants. Evaluation of S(1), F(1), and F(2) generations revealed that flower color in these populations was controlled by 2 alleles at one locus with blue flower color completely dominant to white. We propose that this locus be named white flower with alleles W and w. (+info)Genetic control of floral morph in tristylous Pickerelweed (Pontederia cordata L.). (6/9)
(+info)Gibberellin-producing endophytic fungi isolated from Monochoria vaginalis. (7/9)
The role of endophytic fungi in plant growth and development is well documented. However, endophytic fungi with growth promotion capacity have never been isolated from weeds previously. In the current study, we isolated 8 fungal endophytes from the roots of Monochoria vaginalis, a serious weed of rice paddy in Korea. These isolates were screened on Waito-C, in order to identify plant growth promoting metabolites. Two fungal isolates (M5.A & M1.5) significantly promoted the plant height and shoot length of Waito-C during preliminary screening experiments. The culture filtrates (CFs) of M5.A and M1.5 also promoted the shoot length of Echinocloa crusgalli. Gibberellins (GAs) analysis of the CFs of M5.A and M1.5 showed that these endophytic fungi secrete higher quantities of GAs as compared with wild-type G. fujikuroi KCCM12329. The CF of M5.A contained bioactive GAs (GA3, 2.8 ng/ml; GA4, 2.6 ng/ml, and GA7, 6.68 ng/ml) in conjunction with physiologically inactive GA9 (1.61 ng/ml) and GA24 (0.18 ng/ml). The CF of M1.5 contained physiologically active GAs (GA3, 1.64 ng/ml; GA4, 1.37 ng/ml and GA7, 6.29 ng/ml) in conjunction with physiologically inactive GA9 (3.44 ng/ml), GA12 (0.3 ng/ml), and GA24 (0.59 ng/ml). M5.A and M1.5 were identified as new strains of Penicillium sp. and Aspergillus sp., respectively, based on their 18S rDNA sequence homology and phylogenetic analysis.

(+info)Pontederiaceae is a family of monocotyledonous plants, primarily found in aquatic or wetland habitats, characterized by distichous, linear to lanceolate leaves and bilabiate flowers, including notable genera such as Pontederia, Eichhornia, and Heteranthera.
I apologize for any confusion, but "Pontederiaceae" is not a medical term. It is a taxonomic category in botany, specifically the name of a family of flowering plants that includes water hyacinth and pickerelweed. If you have any questions about a medical term or concept, I would be happy to help with those instead!
