    Abstract: This book provides insight into the use of molecular and genomic techniques to the study of populations of critically important species at various geographical scales. It delves into a wide range of issues relevant to biodiversity conservation, such as population differentiation, landscape genomics, ecological interactions, phylogenetics, phylogeography, metagenomics, molecular methods, and data processing. The current rate of biodiversity loss is unprecedented and valuable genetic resources are being lost at an alarmingly rate. Effective strategies to conserve these genetic resources are essential to maintain healthy ecosystems with inter-dependent species. The book is an invaluable resource for training undergraduate and graduate students, postdoctoral fellows, and for young researchers. This book is particularly useful for the policy makers and academics who want to learn about important concepts in population and conservation genetics and genomics.

    Abstract: Under ongoing climate changes, natural and cultivated habitats of major crops are being continuously disturbed. Such conditions impose and exacerbate abiotic and biotic stressors. Drought, salinity, flood, cold, heat, heavy metals, metalloids, oxidants, irradiation, etc. are important abiotic stressors, while diseases and infections caused by plant pathogens, such as fungal agents, bacteria and viruses, are major biotic stresses. In many instances, stresses have become the major limiting factor for agricultural productivity and exert detrimental role on growth and yield of the crops. To help feed an ever increasing world population and to ensure global food security, concerted efforts from scientists and researchers have identified strategies to manage and mitigate the impacts of climate-induced stresses. This book, summarizing their findings, is aimed at crop improvement beyond such kind of barriers, by agronomic practices (genetics, breeding, phenotyping, etc.) and biotechnological applications, including molecular markers, QTL mapping, genetic engineering, transgenesis, tissue culture, various 'omics' technologies and gene editing. It will cover a wide range of topics under environmental challenges, agronomy and agriculture processes, and biotechnological approaches. Additionally, fundamental mechanisms and applied information on stress responses and tolerance will be discussed. This book highlights problems and offers proper solutions for crop stress management with recent information and up-to-date citations. We believe this book is suitable for scientists, researchers and students working in the fields of agriculture, plant science, environmental biology and biotechnology.

    Notes: Abstract The dielectric constant (K), loss (tanδ), and hence conductivity (σ) of SrTiO3 single crystals have been measured in the frequency region 102–107 Hz and in the temperature range 30°–350° C. Quenching, subjecting the crystals to high electric fields (a.c. or d.c.) and X-ray orγ-ray irradiation, or a combination of these treatments, is found to bring about interesting changes in these properties. An attempt is made to understand the results.

    Notes: There are gaps in what is known about the metabolism of some mammalian small RNA species. Our present observations can be summarized as follows. The level of radiolabeled mature U1 RNA doubled between 2 and 24 hr of label chase, while that of all other small RNA species tested did not change. These results are compatible with the possibility that the nucleotide precursor pool for U1 RNA transcription may be partly segregated, or that there may be a second pathway of U1 RNA formation. Precursors of nucleolar U3 RNA were detected whose electrophoretic mobilities are equivalent to those of transcripts ∼ 14 and ∼ 8 nucleotides longer than the mature species, and which are apparently cytoplasmic. The ladder of U2 RNA precursors showed a gap, suggesting that some of the cleavages during U2 RNA processing are endonucleolytic. We detected an apparent U5 RNA precursor whose electrophoretic mobility is equivalent to that of a species ∼ 1 nucleotide longer than mature U5 RNA. There was a predominant band in the middle of the ladder of U4 RNA precursors (apparently ∼ 3 nucleotides longer than mature U4 RNA) which suggests that U4 RNA maturation may pause briefly at that intermediate. There are apparently two additional species of mature hY3 RNA, which are less abundant and are about 1 and 2 bases longer than the major hY3 RNA species. An apparent hY3 RNA precursor was detected, which may be ∼ 2-3 nucleotides longer than the main mature hY3 RNA species.

    Notes: Two types of UV-light-induced inhibitions of the synthesis of small nuclear RNA species U1, U2, U3, U4, and U5 were described previously: an immediate inhibition and a separate, delayed suppression that requires 1-2 hr of postirradiation cell incubation and UV doses that are about tenfold lower. In the present report, U1 RNA transcription in isolated nuclei from HeLa cells, assayed by RNAase T1 protection, reproduced the delayed inhibition. The sizes of the protected RNA fragments suggest that it is the initiation of U1 RNA transcription that is blocked during this inhibition. Transient expression of a marked human U1 RNA gene that contains 425 and 92 nucleotides of the 5′ and 3′ flanking sequences, respectively, showed delayed, but not immediate inhibition (while the endogenous U1 RNA genes exhibited immediate suppression). This indicates that continuity of the U1 gene flanking sequences beyond those segments and/or chromosomal integration of the U1 gene are not needed for the delayed inhibition, but may be required for the immediate inhibition. Irradiation of a U1 RNA gene, followed by its injection into Xenopus laevis oocyte nuclei, did not reproduce the immediate or delayed inhibitions. This suggests that direct UV radiation damage to DNA in the U1 RNA gene region is not the critical lesion in either the immediate or delayed UV-light-induced inhibitions of U1 RNA synthesis. In addition, the RNAase T1 protection pattern of transcripts synthesized in isolated nuclei from nonirradiated HeLa cells suggests that these cells may produce small amounts of U1 RNA molecules with variant nucleotide sequences in the mature region of the transcript.

    Notes: We observed a series of rapidly labeled U6 RNA bands, which were hybrid selected with U6 DNA, in nonirradiated human cells. The electrophoretic mobility of these bands in denaturing gels was lower than that of the known mature U6 RNA species, and was equivalent to transcripts up to ∼7 nucleotides longer. These multiple U6 RNA species lost their label during a chase without a proportional increase in radioactivity in the known mature U6 RNA, which suggests that a substantial fraction is not processed into the major mature U6 RNA. During a label chase, the multiple U6 RNA bands appeared first in the cytoplasmic fraction and later in nuclei. One of the major rapidly labeled U6 RNA bands had the electrophoretic mobility of an RNA species one nucleotide shorter than the known mature U6 RNA. UV light induced a UV dose-dependent, preferential disappearance of recently synthesized molecules of the U6 RNA species of higher gel electrophoretic mobility, including the known mature U6 RNA. Since this effect was seen in cells pulse-labeled immediately before or after irradiation, it suggests that UV radiation induces the specific degradation of the electrophoretically faster moving species of U6 RNA, which are apparently shorter chains. The effect of UV light was RNA species-specific, was not seen in molecules synthesized long (e.g., 22 hr) before irradiation, and occurred in human and mouse cells.
