"This volume deals with abiotic stress-induced morphological and anatomical changes, abberations in metabolism, strategies and approaches to increase salt tolerance, managing the drought stress, sustainable fruit production and postharvest stress treatments, role of glutathione reductase, flavonoids as antioxidants in plants, the role of salicylic acid and trehalose in plants, stress-induced flowering. The role of soil organic matter in mineral nutrition and fatty acid profile in response to heavy metal stress are also dealt with. Proteomic markers for oxidative stress as a new tools for reactive oxygen species and photosynthesis research, abscisic acid signaling in plants are covered with chosen examples. Stress responsive genes and gene products including expressed proteins that are implicated in conferring tolerance to the plant are presented. Thus, this volume would provides the reader with a wide spectrum of information including key references and with a large number of illustrations and tables."

"The authors of this book have collected the most recent advances and discoveries applied to breeding for abiotic stresses in this book, starting with new physiological concepts and breeding methods, and moving on to discuss modern molecular biological approaches geared to the development of improved cultivars tolerant to most sorts of abiotic stress."

"The book ‘Phytohormones and abiotic stress tolerance in plants’ summarizes the current body of knowledge on crosstalk between plant stresses under the influence of phytohormones, and provides state-of-the-art knowledge of recent developments in understanding the role of phytohormones and abiotic stress tolerance in plants. This book presents information on how modulation in phytohormone levels affect regulation of biochemical and molecular mechanisms."

"Precise regulation of gene expression in both time and space is vital to plant growth, development and adaptation to biotic and abiotic stress conditions. This is achieved by multiple mechanisms, with perhaps the most important control being exerted at the level of transcription. However, with the recent discovery of microRNAs another ubiquitous mode of gene regulation that occurs at the post-transcriptional level has been identified. MicroRNAs can silence gene expression by targeting complementary or partially complementary mRNAs for degradation or translational inhibition. Recent studies have revealed that microRNAs play fundamental roles in plant growth and development, as well as in adaptation to biotic and abiotic stresses. This book highlights the roles of individual miRNAs that control and regulate diverse aspects of plant processes."

"This book provides a comprehensive overview of the multiple strategies that plants have developed to cope with drought, one of the most severe environmental stresses. Experts in the field present 17 chapters, each of which focuses on a basic concept as well as the latest findings.The following major aspects are covered in the book, morphological and anatomical adaptations, physiological responses, biochemical and molecular responses, ecophysiological responses, and responses to drought under field conditions."

"Situasi pandemi Covid-19 mengharuskan karyawan menerapkan protokol kesehatan di lingkungan kerja sebagai cara untuk mengurangi potensi penularan. Penelitian ini bertujuan untuk menganalisis pengaruh modal psychological capital, work stress & leader member exchange terhadap produktivitas karyawan di PT KAI DAOP 1 wilayah Jakarta yang dimediasi oleh kepatuhan terhadap protokol kesehatan. Belum ada penelitian sebelumnya tentang kepatuhan karyawan terhadap protokol kesehatan covid khususnya di perusahaan transportasi. Teori-teori yang dibahas untuk mendukung penyusunan penelitian ini berupa teori-teori yang berkaitan dengan psychological capital, work stress & leader member exchange, dan productivity karyawan. Responden penelitian ini berjumlah 391 karyawan PT KAI di wilayah Daop 1 Jakarta dengan metode penelitian cross sectional menggunakan kuesioner. Analisis penelitian ini menggunakan SEM dan dilakukan dengan software Lisrel 8.80. Hasil penelitian menunjukkan bahwa ada hubungan antara modal psikologis, stres kerja, dan pertukaran pemimpin anggota terhadap produktivitas karyawan di PT KAI DAOP 1 wilayah jakarta yang dimediasi oleh kepatuhan terhadap protokol kesehatan.

The Covid-19 pandemic situation requires employees to implement health protocols in the work environment as a way to reduce the potential for transmission. This study aims to analyze the influence of psychological capital, work stress, and leader member exchange on employee productivity at PT KAI DAOP 1 Jakarta area which is mediated by compliance with health protocols. There is no prior study about employee’s compliance towards covid health protocol, especially in transportation company. The theories discussed to support the preparation of this study are in the form of theories related to psychological capital, work stress, leader member exchange, compliance theory, and employee productivity. This study used respondents in the form of 391 employees of PT KAI in the Daop 1 Jakarta region with a cross-sectional research method using a questionnaire. The analysis of this study used SEM and was carried out with Lisrel 8.80 software. The results showed that there was a relationship between psychological capital, work stress, leader member exchange, and in employee productivity at PT KAI DAOP 1 Jakarta area which is mediated by compliance with health protocols."

"As a broadcaster and medical columnist, Dr Smith receives many letters each year, asking questions about coping with stress, and in this book he sets out to answer the most common ones. In doing so, he offers advice, information and reassurance."

"ABSTRACTJarak pagar (Jatropha curcasL.), salah satu tanaman sumber bahan bakar nabati tropis, telah terkenal karena ketahanannya terhadapcekaman kekeringan, akan tetapi, kemampuannya untuk tumbuh pada lingkungan yang kering masih jarang diteliti.Perubahan status air daun, kadar klorofil, suhu permukaan daun, konduktansi stomata, kadar prolin danabcisic acid (ABA), laju transpirasi dan fotosintesis dikaji pada empat genotip jarak pakar (IP-1A, IP-2M, Unggul lokal dan Daunkuning) yang diperlakukan cekaman kekeringan pada lahan pasir pantai di Jawa Tengah, Indonesia. Cekaman kekeringan menurunkan secara signifikan status air daun, kadar klorofil daun, konduktansi stomata, laju transpirasi dan fotosintesis, dan meningkatkan suhu daun, kadar prolin dan ABA. Genotip tahan (IP-1A dan IP-2M) memiliki status air daun, kadar klorofil dan laju fotosintesis lebih tinggi secara signifikan dibandingkan dengan genotip yang peka (Unggullokal dan Daun kuning). Tidak terdapat perbedaan yang nyata di ntara genotip jarak pagar terhadap suhu daun, konduktansi stomata dan laju transpirasi.

AbstractJatropha curcas L., an important tropical biofuel crop, is reputed for its drought resistance, however, its ability to perform in dry conditions has still hardly been investigated. Changes in leaf water status, chlorophyll content, leaf surface temperature, stomatal conductance, proline and abcisic acid (ABA) content, transpiration and photosyntheticrate were studied in fourJatropha genotypes (IP-1A, IP-2M, Local superior and Yellow leaf) and subjected to drought stress in coastal sandy land conditions in Central Java, Indonesia. Drought stress significantly decreased the leaf water status, leaf chlorophyll content, stomatal conductance, transpiration and photosynthetic rate, and increased leaftemperature, proline and ABA content. Resistant genotypes (IP-1A and IP-2M) had significantly higher leaf water status, chlorophyll content and photosynthetic rate than susceptible genotypes (Local superior and Yellow leaf). There were no differences between theJatropha genotypes on leaf temperature, stomatal conductance and transpiration rate."
