Abstract
BACKGROUND AND AIMS Wind pollination has evolved repeatedly in flowering plants, yet the identification of a wind pollination syndrome as a set of integrated floral traits can be elusive. Thalictrum (Ranunculaceae) comprises temperate perennial herbs that have transitioned repeatedly from insect to wind pollination while also exhibiting mixed pollination, providing an ideal system to test for evolutionary correlation between floral morphology and pollination mode in a biotic to abiotic continuum. Moreover, the lack of floral organ fusion across this genus allows testing for specialization to pollination vectors in the absence of this feature. METHODS We expanded phylogenetic sampling in the genus from a previous study using six chloroplast loci, which allowed us to test whether species cluster into distinct pollination syndromes based on floral morphology. We then used multivariate analyses on floral traits followed by ancestral state reconstruction of the emerging flower morphotypes and determined whether these traits are evolutionarily correlated under a Bayesian framework with Brownian motion. KEY RESULTS Floral traits fell into five distinct clusters, which were reduced to three after considering phylogenetic relatedness and were largely consistent with flower morphotypes and associated pollination vectors. Multivariate evolutionary analyses found a positive correlation between the lengths of floral reproductive structures (styles, stigmas, filaments and anthers). Shorter reproductive structures tracked insect-pollinated species and clades in the phylogeny, whereas longer structures tracked wind-pollinated ones, consistent with selective pressures exerted by biotic vs. abiotic pollination vectors, respectively. CONCLUSIONS Although detectable suites of integrated floral traits across Thalictrum were correlated with wind or insect pollination at the extremes of the morphospace distribution, a presumed intermediate, mixed pollination mode morphospace was also detected. Thus, our data broadly support the existence of detectable flower morphotypes from convergent evolution underlying the evolution of pollination mode in Thalictrum, presumably via different paths from an ancestral mixed pollination state.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Thalictrum (Ranunculaceae) is known for its important alkaloids which have been reported to exhibit various pharmacological activities, viz. antitumor, antimicrobial, antitussive, antiamebic, hypotensive effects, HIV antiviral, etc. Throughout the world, the plant has been used as a tonic, purgative, stimulant, aperient and is utilized in various systems of medicine in the treatment of various ailments like snake bite, jaundice, rheumatism, stomachache, wounds, swellings, uterine tumors, paralysis, joints pain, nervous disorders, toothache, diarrhea, piles, fever, peptic ulcer, ophthalmic, headache, diuretic, dyspepsia, convalescence, etc. AIMS OF THIS REVIEW: To bring together all the information regarding the botany, phytochemistry, ethnobotany and ethnopharmacology of Thalictrum and identify the gaps in the existing studies so that full medicinal potential of the genus can be realized. METHODS Available literature on botany, geography, traditional uses, phytochemicals, and pharmacology was gathered by referring to library and electronic searches in PubMed, Science Direct, Google Scholar, relevant journals and books. RESULTS A variety of phytochemicals like alkaloids, essential oils, glycosides, phenols and terpenoids have been reported from Thalictrum species. Alkaloids are the most dominant diverse group with 178 different types. The crude extracts and isolates exhibit a gamut of pharmacological activities, namely anticancer, antimalarial, antioxidant, antipyretic, anti-tumor, ant-influenza virus, contraceptive and immunosuppressive. Northalrugosidine, an alkaloid from T. alpinum shows in vivo antileishmanial activity. So far, cytotoxic effects of only three Thalictrum species, viz. T. dasycarpum, T. foliolosum and T. simplex have been reported. Thl isolated from T. simplex is found to be 50% toxic (CC50%) at the concentration ranging from 53 to 95 μM. CONCLUSIONS Thalictrum has tremendous medicinal values used in many traditional systems of medicine. It has multiple chemical components and still there is scope to explore more. Multiple chemical constituents and its utilization signify its high demand in the drug markets or pharmaceutical companies. In depth phytochemical studies along with in vitro studies with respect to their active principles can help in tapping the full medicinal potential of the genus.

Abstract
PREMISE Future reductions in snow cover are expected in temperate climates, likely leading to more soil-freezing events and damage to plant tissues. However, whether and how plants can compensate for this damage may depend on the timing of damage and on plant allocations to seed size and number. We need more information about how seed production, germination, and seedling recruitment might respond to changes in snow cover. METHODS We manipulated snow cover over three seasons in a common garden experiment with four treatments: (1) "control," where snowpack was left unmanipulated throughout the winter season; (2) "late addition," where snowpack was experimentally increased at the end of the winter season in order to delay the onset of spring; (3) "late removal," where snowpack was experimentally reduced at the end of the winter season in order to advance the onset of spring; and (4) "freeze," a consistent removal treatment, where snowpack was experimentally reduced following every substantial snowfall in order to induce freeze-thaw events in the soil. In all treatments, we measured survival, growth, reproduction, and recruitment of a native perennial herb, Thalictrum dioicum. RESULTS Reduced snow cover minimally influenced adult survival. Instead, individuals that experienced reduced snow cover throughout the winter produced more massive seeds, whereas individuals that experienced a single snow removal at the end of the season produced less massive seeds. Seedling recruitment was lower in the removal treatments than in the control, as a result of failure to germinate in the freeze treatment and seedling mortality in the late removal treatment. CONCLUSIONS Both reduced snow cover throughout the winter and a single late snow removal in the spring reduced seedling recruitment, but for different reasons, suggesting that a holistic approach to the life cycle is needed to understand responses to shifting climates.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Thalictrum minus L., which is widespread across Eurasia, is utilized as a folk medicine for treating dysentery, bedsore, fungal infection and lung inflammation in China, Mongolia and Iran. AIM OF THE STUDY A Mongolian folk medicinal plant named Thalictrum minus L. (TML) has been extensively used for the treatment of lung inflammation, bacterial and fungal infection and tuberculosis. Our present study aims to investigate the effectiveness of TML against particulate matter (PM)-induced acute lung injury (ALI) and the potential underlying mechanisms. MATERIALS AND METHODS Initially, HPLC-Q-TOF was applied for the qualitative analysis and HPLC was used for quantitative analysis of main components in TML. Then, the mice model of ALI was induced by PM via intratracheally instilled with 50 mg/kg body weight of Standard Reference Material1648a (SRM1648a), and TML (10, 20, 40 mg/kg) were administered orally 1 h prior to PM. The efficacy and molecular mechanisms in the presence or absence of TML were elucidated. RESULTS Eleven main ingredients were detected in TML and the contents of homoorientin and berberine were quantified. Additionally, the results demonstrated that TML profoundly inhibited weight loss in mice and ameliorated lung pathological injury induced by PM. Furthermore, we also found that TML significantly decreased the lung wet to dry weight (W/D) ratios, reduced total protein in bronchoalveolar lavage fluid (BALF), and effectively attenuated PM-induced increased leukocyte and macrophages in BALF. Meanwhile, TML could pronouncedly inhibited myeloperoxidase (MPO) activity in lung tissues, decreased the PM-induced inflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β), reduced nitric oxide (NO) and increased superoxide dismutase (SOD) in BALF. In addition, TML markedly facilitated the expression of p-AMPK-Nrf2 and suppressed the expression of KEAP, prohibited the activation of the MAPKs-NLRP3/caspase-1 and cyclooxygenase-2 (COX2), and inhibited apoptotic pathways. CONCLUSION These findings indicated that TML attenuated PM-induced ALI through suppressing the release of inflammatory cytokines and alleviating oxidative damage correlated with the AMPK-Nrf2/KEAP signaling pathways, MAPKs-NLRP3/caspase-1 signaling pathways, as well as apoptotic pathways.

Abstract
Phytochemical investigation on the 70% EtOH extract of the roots of Thalictrum foliolosum DC. resulted in the isolation of three new isoquinoline alkaloids, 5,6,7,12-tetramethoxy-2-methyl-13-hydroxy-11-(4'-methoxycarbonylphenoxy)benzylisoquinoline (1), 5,6,7,12-tetramethoxy-2-methyl-13-hydroxy-11-(4'-carbonylphenoxy) benzylisoquinoline (2), and 3-methoxy-10-O-acetylprodensiflorin B (3). The new structures were elucidated by using spectroscopic data (NMR, IR, UV, and MS). The isolated alkaloids were tested in vitro for cytotoxic potentials against six human lung cancer cell lines (H460, H23, HTB-58, A549, H441, and H2170). As a result, alkaloids 1 and 2 exhibited significant cytotoxic activities against all the tested tumor cell lines with IC50 values less than 20 μM.

Abstract
Thalictrum (Ranunculaceae) is an extremely abundant medicinal plant source. Due to their marked ethnopharmacological usages in folk medicine of China and the large number of potentially active chemical constituents, they may be a rich source for new chemicals for drug R&D. Here, an investigation on traditional functions and folk therapeutic uses of Thalictrum plants from China, as well as their main chemical constituents, was undertaken. It showed that 43 Thalictrum plants have long been used as folk medicine to treat many diseases in different races of China. In addition, the correlation between folk therapeutic effects and chemical constituents, and the modem pharmacological activities, are discussed as well as the prospect of isolation and development of new drugs from this genus of plants.

Abstract
The in vitro anti-influenza virus effects of some isoquinoline alkaloids, isolated from Thalictrum species (Ranunculaceae), growing in Mongolia and Sweden have been studied. (-)-thalimonine (Thl) and (-)-thalimonine N-oxide, isolated from the Mongolian plant T. simplex, inhibited markedly the influenza virus reproduction in vitro; thalictuberine N-oxide was less effective. The synthetic analogues of Thl as well as the rest of the tested alkaloids, isolated from T. foetidum and T. flavum, were not active. At a concentration range between 0.1 - 6.4 microM Thl inhibited viral reproduction in a selective and specific way.
