Rice is the staple food for more than half of the world's population, yet cold temperatures during the cropping period cause a significant loss of yield. To cope with the world's increasing population, it is necessary to develop high yielding rice varieties that are tolerant to abiotic stress conditions, such as drought, salinity, and cold. This book provides a clear understanding of cold stress in rice in the hopes that it will provide insight to the subject for further research so that rice plants may be grown efficiently in cold regions with high productivity.

As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. Thus, investigating the effect of low temperatures is important. The effect of low temperature on rice production are diverse and complex. Since a large portion of maize crops are grown for purposes other than human consumption, rice is the most important grain with regard to human nutrition and caloric intake, providing more than one fifth of the calories consumed worldwide by humans. The plant has many different variations, but is generally a short living plant, with an average life span of 3-7 months, depending on the climate and the variety. It is not a water plant but substantial amounts of water are required for the planting. Cultivated species of rice are considered to be semi-aquatic annuals. The height of the plant can range from 0.4m to over 5m in some floating rices. Rice is cultivated in many different ways around the world, the different methods used can differ greatly even in the same locality. Methods of growing differ greatly in different localities, but in most Asian countries the traditional hand methods of cultivating and harvesting rice are still practiced. The fields are prepared by plowing, fertilizing, and smoothing. The seedlings are started in seedling beds and, after 30 to 50 days, are transplanted by hand to the fields, which have been flooded by rain or river water. During the growing season, irrigation is maintained by dike-controlled canals or by hand watering. The fields are allowed to drain before cutting. In the United States and in many parts of Europe, rice cultivation has undergone the same mechanization at all stages of cultivation and harvesting as have other grain crops. This book provides a clear understanding of cold stress in rice in the hopes that it will provide insight to the subject for further research so that rice plants may be grown efficiently in cold regions with high productivity.

This book is open access under a CC BY 4.0 license. By 2050, human population is expected to reach 9.7 billion. The demand for increased food production needs to be met from ever reducing resources of land, water and other environmental constraints. Rice remains the staple food source for a majority of the global populations, but especially in Asia where ninety percent of rice is grown and consumed. Climate change continues to impose abiotic and biotic stresses that curtail rice quality and yields. Researchers have been challenged to provide innovative solutions to maintain, or even increase, rice production. Amongst them, the ‘green super rice’ breeding strategy has been successful for leading the development and release of multiple abiotic and biotic stress tolerant rice varieties. Recent advances in plant molecular biology and biotechnologies have led to the identification of stress responsive genes and signaling pathways, which open up new paradigms to augment rice productivity. Accordingly, transcription factors, protein kinases and enzymes for generating protective metabolites and proteins all contribute to an intricate network of events that guard and maintain cellular integrity. In addition, various quantitative trait loci associated with elevated stress tolerance have been cloned, resulting in the detection of novel genes for biotic and abiotic stress resistance. Mechanistic understanding of the genetic basis of traits, such as N and P use, is allowing rice researchers to engineer nutrient-efficient rice varieties, which would result in higher yields with lower inputs. Likewise, the research in micronutrients biosynthesis opens doors to genetic engineering of metabolic pathways to enhance micronutrients production. With third generation sequencing techniques on the horizon, exciting progress can be expected to vastly improve molecular markers for gene-trait associations forecast with increasing accuracy. This book emphasizes on the areas of rice science that attempt to overcome the foremost limitations in rice production. Our intention is to highlight research advances in the fields of physiology, molecular breeding and genetics, with a special focus on increasing productivity, improving biotic and abiotic stress tolerance and nutritional quality of rice.

Seminar paper from the year 2023 in the subject Biology - Genetics / Gene Technology, grade: 8.0, , language: English, abstract: Recently, a mini core panel of 98 genotypes representing the diversity of Indian rice germplasm was identified. This mini core is a very important resource that can be evaluated for specific traits of interest to identify superior genotypes that could be used as parents in breeding programmes. The present study was focused on a systematic evaluation of mini core rice collection along with a set of germplasm from the North Eastern Hill Region under cold stress with following specific objectives: To study and compare the effect of three dates of sowing (early, medium and late) on rice mini core collection with respect to yield contributing traits, to determine the trait that most affects yield under stress through path coefficient analysis, to study the effect of cold stress at booting stage on pollen and spikelet fertility under controlled low temperature conditions and to identify tolerant and susceptible genotypes. Rice farming is the largest single use of land for producing food. Ninety percent of the rice is produced in Asia, and it totaled 696 million tons in 2010. Rice production is one of the most important economic activities on Earth. Only 7% of all rice production is exported from its country of origin. Various abiotic stresses directly or indirectly affect the physiological status of rice and negatively alter its overall metabolism, often with impacts on grain yield. Cold stress is one of the abiotic stresses which are common problem of rice cultivation. Cold stress causes various injuries to rice seedlings in low-temperature and high-altitude areas and is therefore an important factor affecting rice production in such areas. Rice is a cold-sensitive plant that has its origin in tropical or subtropical areas, and cold damage can cause serious yield losses. Low temperature effects the rice cultivation mainly in two stages of development i.e., seedling and booting. In both of them, cold temperature has harmful effects on crop productivity, as in the first case the number of established plants is affected and in the booting stage pollen sterility can be induced by cold, decreasing the final number of grains.

Plants have to manage a series of environmental stresses throughout their entire lifespan. Among these, abiotic stress is the most detrimental; one that is responsible for nearly 50% of crop yield reduction and appears to be a potential threat to global food security in coming decades. Plant growth and development reduces drastically due to adverse effects of abiotic stresses. It has been estimated that crop can exhibit only 30% of their genetic potentiality under abiotic stress condition. So, this is a fundamental need to understand the stress responses to facilitate breeders to develop stress resistant and stress tolerant cultivars along with good management practices to withstand abiotic stresses. Also, a holistic approach to understanding the molecular and biochemical interactions of plants is important to implement the knowledge of resistance mechanisms under abiotic stresses. Agronomic practices like selecting cultivars that is tolerant to wide range of climatic condition, planting date, irrigation scheduling, fertilizer management could be some of the effective short-term adaptive tools to fight against abiotic stresses. In addition, “system biology” and “omics approaches” in recent studies offer a long-term opportunity at the molecular level in dealing with abiotic stresses. The genetic approach, for example, selection and identification of major conditioning genes by linkage mapping and quantitative trait loci (QTL), production of mutant genes and transgenic introduction of novel genes, has imparted some tolerant characteristics in crop varieties from their wild ancestors. Recently research has revealed the interactions between micro-RNAs (miRNAs) and plant stress responses exposed to salinity, freezing stress and dehydration. Accordingly transgenic approaches to generate stress-tolerant plant are one of the most interesting researches to date. This book presents the recent development of agronomic and molecular approaches in conferring plant abiotic stress tolerance in an organized way. The present volume will be of great interest among research students and teaching community, and can also be used as reference material by professional researchers.
