    Abstract Sexual reproduction is the predominant mode of perpetuation for flowering plant species. Investigating the reproductive strategies of plants has grown to become a vast area of research and, in crop plants, covers events from flowering to fruit and seed development; in wild species, it extends up to seed dispersal and seedling recruitment. Thus, reproduction determines the extent of yield in crop plants and, in wild plants, also determines the efficacy of recruiting new adults to the population, making this field important both from fundamental and applied plant biology perspectives. Moreover, in light of the growing concerns regarding food and nutritional security for the growing population and preserving biological diversity, reproductive biology of flowering plants has acquired special significance. Extensive studies on various facets of reproduction are being carried out around the world. However, these studies are scattered across research journals and reviews from diverse areas of biology. The present volume covers the whole spectrum of reproductive ecology, from phenology and floral biology, to sexuality and pollination biology/ecology including floral rewards, breeding systems, apomixis and seed dispersal. In turn, transgene flow, its biosafety and mitigation approaches, and the ‘global pollinator crisis’, which has become a major international concern in light of the urgent need to sustain crop yield and biodiversity, are discussed in detail. Given its scope, the book offers a valuable resource for students, teachers and researchers of botany, zoology, ecology, agriculture and forestry, as well as conservation biologists.

    Abstract Aim: The objective of this research was to conduct a comparison and evaluate the pain perception and time of onset of 2% lignocaine 1:80,000 epinephrine with 4% articaine 1:100,000 epinephrine in the pediatric population.
    Materials and methods: A split-mouth randomized control trial was conducted on 50 children aged 9-14 years who required inferior alveolar nerve block (IANB) anesthesia for bilateral dental treatment in the mandibular arch. The time of onset was recorded when no sensation was reported even when maximum electrical stimulus was applied in an electric pulp testing (EPT). The pain perception was assessed using a visual analog scale (VAS) rated by the patient for subjective symptoms and face, legs, activity, cry, and consolability (FLACC) scale for objective pain rated by the operator.
    Results: The mean onset of time, pain-VAS, and FLACC score decreased by 1.31, 12.07, and 18.39%, respectively in 4% articaine as compared to 2% lignocaine but the difference did not reach statistical significance (
    Clinical significance: Local anesthesia (LA) is one of the main methods of pain management in pediatric practice which makes it essential to choose an LA agent with a shorter time of onset and less pain on administration.

    Abstract Synergids are metabolically dynamic cells of the egg apparatus and represent an important component of the female gametophyte. Besides directing the growth of the pollen tube towards the micropylar end of the embryo sac, these ephemeral structures make room for the pollen tube cytoplasm. The nature of chemotrophic substances that direct the growth of the pollen tube, the mechanism of degeneration of one of the synergids before fertilization and the molecular aspects of synergid morphogenesis have been studied in detail.

    Abstract The megasporangium serves as a model system for understanding the concept of individual cell identity, and cell-to-cell communication in angiosperms. As development of the ovule progresses, three distinct layers, the epidermal (L1), the subepidermal or the hypodermal (L2) and the innermost layers (L3) are formed along the MMC (megaspore mother cell). The MMC, which is the primary female germline cell, is initiated as a single subepidermal cell amongst several somatic cells. MMC development is governed by various regulatory pathways involving intercellular signaling, small RNAs and DNA methylation. The programming and reprograming of a single nucellar cell to enter meiosis is governed by 'permissive' interacting processes and factors. Concomitantly, several nucellar sister cells are prevented from germline fate also by a set of 'repressive' factors. However, in certain angiosperms, anomalies in development of the female gametophyte have been observed. The sporophytic tissue surrounding the female gametophyte affects the gametophyte in multiple ways. The role of genes and transcription factors in the development of the MMC and in the regulation of various processes studied in selected model plants such as

    Abstract Fungal endophytes are known to play a vital role in perpetuation and survival of orchids. While orchid–mycorrhizal relationship has been studied in detail, dynamics of orchid–non-mycorrhizal associations are insufficiently explored. There is paucity of empirical evidence for host specificity, phylogenetic preference, co-evolution, and habitat selection amongst orchids and their non-mycorrhizal endophytes. We explored these aspects by studying the root associated non-mycorrhizal fungal assemblages from 11 epiphytic orchid species in two tropical communities located at Indo-Burma biodiversity hotspot. A total of 94 non-mycorrhizal fungal isolates were mined. Of these 55 isolates could be identified at species level, while 39 isolates were circumscribed at generic level using the ITS region. The core group fungal assemblages predominantly belonged to Ascomycota. The extent of mutualistic reliance was inferred by mapping the bipartite interaction in a phylogenetic framework. The analysis shows that the orchid–non-mycorrhizal associations are neither clade specific nor nested, rather they depend on the availability of suitable fungal taxon at the sites. The study also indicates the absence of phylogenetic preference between the partners. However, topology of the bipartite interaction network suggests that there has been a shift from specialised interaction in the basal clades, to generalised one in the later evolved clades.

    Abstract Solanaceous plants are ubiquitous and are able to colonize degraded, abandoned and metal polluted habitats. Members of the family have evolved interesting extrinsic and intrinsic traits to combat the metal toxicity in multiple ways. Indumentum constituted mostly of trichome layer provides structural defense for both biotic stress (herbivory, oviposition, microbial pathogenesis) and abiotic stress (like drought, heat, freezing, photooxidation and UV radiation). Plants with heavy metal tolerance can accumulate toxic heavy metals in their trichomes as a part of their elemental defense detoxification strategy. Apart from the canonical functions, trichomes support ion and metal homeostasis, including the sequestration, compartmentalization, accumulation and excretion of heavy metals in many ways. The trichomes in Solanaceae are known to have a key role in the detoxification of Cd, Ni, Pb and Zn. Expressed sequence tag (EST)‐based large‐scale gene analysis in tobacco has indicated that trichomes are biologically active and stress–responsive structures. Trichome secretions and exudates also play an active role in metal detoxification process. Given that trichomes provide chemical defense from heavy metal stresses in the form of sequestration and extrusion, the plants having trichomes have potential role in remediation of contaminated soils. Solanaceae trichomes can serve as important model tissues that can be modified to attenuate metal toxicity, serve as environmental indicators and enhance phytoremediation potential of the family.

    Abstract Consumption of pollination reward by felonious means in a plant species can influence the foraging behavior of its pollinator and eventually the reproductive success. So far, studies on this aspect are largely confined to interaction involving plant-pollinators and nectar robbers or thieves. However, a foraging guild in such interactions may also include floral herbivores or florivores. There is a paucity of information on the extent to which nectar larcenists may influence the foraging behavior of the pollinator and reproductive fitness of plants in the presence of a florivore. We investigated various forms of larceny in the natural populations of

    Abstract Introduction: The success of endodontic treatment is achieved by the complete elimination of pulpal infection and protection from future invasion of microorganisms. Due to the complex structure of the root canal, complete eradication of microorganisms is not possible and is a major challenge for successful endodontic treatment. Therefore, microbiological studies are needed to explore the effect of various disinfection methods.
    Aim and objective: The aim of this study is to compare the effectiveness of root canal disinfection by using a diode laser (in pulse and continuous modes) and sodium hypochlorite by microbiological assessment.
    Materials and methods: Forty-five patients were selected and randomly divided into three groups. After gaining patency to the root canal the first sample from the root canal was taken using a sterile absorbent paper point and transferred to a sterile tube containing a normal saline medium. Biomechanical preparation was performed with Dentsply Protaper hand files of each corresponding group and was disinfected with group I (diode light amplification by stimulated emission of radiation (LASER) 980 nm with 3 W in continuous mode for 20 seconds), group II (diode LASER 980 nm with 3 W in pulse mode for 20 seconds), group III (irrigated with 5.25% of sodium hypochlorite for 5 minutes). Pre- and post-samples of each group were inoculated on sheep blood agar and examined for any bacterial growth. After the microbial evaluation of the total microbial count of pre- and post-samples, the data obtained were tabulated and statistically analyzed.
    Results: The data were evaluated and analyzed using analysis of variance (ANOVA) on Statistical Package for the Social Sciences (SPSS) software. Groups I, II, and III all three groups showed significant differences (
    Conclusion: The study concluded that the diode laser in continuous mode is more efficacious than the diode laser in pulse mode and 5.2% sodium hypochlorite, respectively.
