Phytotoxicity assessments were performed to compare responses of Typha latifolia (L.) seeds to atrazine (only) and atrazine + S-metolachlor exposure concentrations of 0.03, 0.3, 3, and 30 mg L(-1), as well as permethrin exposure concentrations of 0.008, 0.08, 0.8, and 8 mg L(-1). All atrazine + S-metolachlor exposures resulted in significantly reduced radicle development (p < 0.001). A stimulat...

Wound healing potential of ethanolic extract of Anogeissus latifolia bark (ALE) for treatment of dermal wounds in rats was studied on excision and incision wound models. HPTLC of the total extract was recorded for the purpose of standardization. Various parameters of incision wound, viz. epithelization period, scar area, tensile strength and hydroxyproline measurements along with wound contract...

To elucidate the mechanism(s) underlying dioecious flower development, the present study analyzed a SUPERMAN (SUP) homolog, SlSUP, which was identified in Silene latifolia. The sex of this plant is determined by heteromorphic X and Y sex chromosomes. It was revealed that SlSUP is a single-copy autosomal gene expressed exclusively in female flowers. Introduction of a genomic copy of SlSUP into t...

One fundamental signature of reinforcement is elevated prezygotic reproductive isolation between related species in sympatry relative to allopatry. However, this alone is inadequate evidence for reinforcement, as traits conferring reproductive isolation can occur as a by-product of other forces. We conducted crosses between Silene latifolia and S. diclinis, two closely related dioecious floweri...

Orchis latifolia belonging to the family Orchidaceae is extensively used in traditional Indian medicine against a wide spectrum of ailments including dysentery, diarrhoea, chronic fever, wounds, burns, fractures and general weakness. The present study relates to the bioactive extracts from O. latifolia against multidrug resistant (MDR) bacteria and Candida albicans. Methanolic extract of O. lat...

Silene latifolia is a dioecious plant with heteromorphic sex chromosomes. The sex chromosomes of S. latifolia provide an opportunity to study the early events in sex chromosome evolution because of their relatively recent emergence. In this article, we present the genetic and physical mapping, expression analysis, and molecular evolutionary analysis of a sex-linked gene from S. latifolia, DD44 ...

Constructed wetlands are a potential method for the removal of two pharmaceutical and personal care products from wastewater effluent. Triclosan (TCS; 5-chloro-2-[2,4-dichlorophenoxy]phenol) and triclocarban (TCC; 3,4,4'-trichlorocarbanillide) are antimicrobial agents added to a variety of consumer products whose accumulation patterns in constructed wetlands are poorly understood. Here, we repo...

The dioecious plant Silene latifolia possesses evolutionarily young sex chromosomes, and so serves as a model system to study the early stages of sex chromosome evolution. Sex chromosomes often differ distinctly from autosomes in both their structure and their patterns of evolution. The S. latifolia Y chromosome is particularly unique owing to its large size, which contrasts with the size of sm...

Anogeissus latifolia is widely used in the Indian indigenous system of medicine and is reported to contain leucocyanidins and tannoid principles like ellagic acid and its derivatives. In view of its wide use and its chemical composition, this study was aimed at examining the antioxidant activity of the extract of A. latifolia. The extract was studied for total antioxidant capacity, hydrogen-don...

Birds do it, bees do it—and now it appears that even plants do it. No, it’s not what you’re thinking. Sexual reproduction is obviously well-known in plants. Rather, the phenomenon in question is equalizing sex chromosome expression in males and females. In animals where males are XY and females are XX, the Y chromosome has lost most of its genes, so X chromosome expression is adjusted to keep t...
