The Relationship

Betalains are applicable to many aspects of life, and their properties, characteristics, extraction and biosynthesis process have been thoroughly studied. Although betalains are functionally similar to anthocyanins and can substitute for them to provide pigments for plant color, it is rare to study the roles of betalains in plant responses to adverse environmental conditions. Owing to their antioxidant capability to remove excess reactive oxygen species (ROS) in plants and humans, betalains have attracted much attention due to their bioactivity. In addition, betalains can also act as osmotic substances to regulate osmotic pressure in plants and play important roles in plant responses to adverse environmental conditions. The study of the physiological evolution of betalains is almost complete but remains complicated because the evolutionary relationship between betalains and anthocyanins is still uncertain. In this review, to provide a reference for the in-depth study of betalains compared with anthocyanins, the biochemical properties, biosynthesis process and roles of betalains in response to environmental stress are reviewed, and the relationship between betalains and anthocyanins is discussed.

Adverse Environmental Conditions

Abstract In terrestrial environments, water and nutrient availabilities and temperature conditions are highly variable, and especially in extreme environments limit survival, growth, and reproduction of plants. To sustain growth and maintain cell integrity under unfavourable environmental conditions, plants have developed a variety of biochemical and physiological mechanisms, orchestrated by a large set of stress-responsive genes and a complex network of transcription factors. Recently, cycling DOF factors (CDFs), a group of plant-specific transcription factors (TFs), were identified as components of the transcriptional regulatory networks involved in the control of abiotic stress responses. The majority of the members of this TF family are activated in response to a wide range of adverse environmental conditions in different plant species. CDFs regulate different aspects of plant growth and development such as photoperiodic flowering-time control and root and shoot growth. While most of the functional characterization of CDFs has been reported in Arabidopsis, recent data suggest that their diverse roles extend to other plant species. In this review, we integrate information related to structure and functions of CDFs in plants, with special emphasis on their role in plant responses to adverse environmental conditions.

Adverse Environmental Conditions

Strategies for surviving an environmental stress in winter can differ from those that provide protection from the same stress when it occurs in summer. During the growing season, escape mechanisms from stresses tend to prevail, as periods of adversity are generally brief. In winter, adverse environmental conditions have a high probability of persisting for lengthy periods and consequenctly, survival depends on tolerance. Spring is a period of uncertainty as to whether the risk of flooding has passed, and seeds differ markedly in their ability to resume germination if interrupted by re-imposition of winter conditions. When growing plants are flooded in summer, brief periods of accelerated anaerobic metabolism can alleviate energy shortages while improved aeration tissues develop, which then remove the dangers of prolonged anaerobiosis. By contrast, overwintering species, if they are highly tolerant of prolonged anoxia, may down-regulate metabolism when flooded and thus reduce the risk of exhausting carbohydrate supplies. Ventilation of underground organs in winter is still possible but is dependent on specialized mechanisms that can provide a through flow of air from emergent stems to buried or submerged organs. The tree form also presents metabolic and morphological problems for surviving wet conditions at critical seasons.Key words : anoxia, flooding summer, winter stress, plants, crops.

The Way

A Palestinian-Israeli poet declares a new state whose language, “Homelandic,” is a combination of Arabic and Hebrew. A Jewish-Israeli author imagines a “language plague” that infects young Hebrew speakers with old world accents, and sends the narrator in search of his Arabic heritage. This book brings together such startling visions to offer the first in-depth study of the relationship between Hebrew and Arabic in the literature and culture of Israel/Palestine. More than that, the book presents a captivating portrait of the literary imagination's power to transgress political boundaries and transform ideas about language and belonging. Blending history and literature, the book traces the interwoven life of Arabic and Hebrew in Israel/Palestine from the turn of the twentieth century to the present, exposing the two languages' intimate entanglements in contemporary works of prose, poetry, film, and visual art by both Palestinian and Jewish citizens of Israel. In a context where intense political and social pressures work to identify Jews with Hebrew and Palestinians with Arabic, the book finds writers who have boldly crossed over this divide to create literature in the language of their “other,” as well as writers who bring the two languages into dialogue to rewrite them from within. Exploring such acts of poetic trespass, the book introduces new readings of canonical and lesser-known authors, including Emile Habiby, Hayyim Nahman Bialik, Anton Shammas, Saul Tchernichowsky, Samir Naqqash, Ronit Matalon, Salman Masalha, A. B. Yehoshua, and Almog Behar. By revealing uncommon visions of what it means to write in Arabic and Hebrew, the book will change the way we understand literature and culture in the shadow of the Israeli–Palestinian conflict.

The basic moments of a process of obtaining apple tetraploids as donors of diploid gametes for apple breeding with polyploidy using are demonstrated. In industrial terms, triploids are of the greatest importance. The manifested effect of heterosis leads to the improvement of many characteristics - higher resistance to diseases, pests and adverse environmental conditions, greater autogamy than in diploids, less pronounced periodicity of fruiting, larger fruits and a convenient crown for harvesting. Triploids are developed as a result of crosses 2n × 3n or 2n × 4n. Tetraploids are necessary for more successful apple breeding with polyploidy using. For industry they are not of great importance but they are of interest as donors of diploid non-reduced gametes and allow to make the selection process more directional. One of the methods of experimental polyploidy is the induction of polyploids using mutagenes. The germs were treated with colchicines at concentrations 0.1% - 0.4% during 24 and 48 hours. According to the morphology the obtained plants were divided into five groups. Colchicine concentrations 0.3% and 0.4% during 48 hours of the treatment had a disastrous impact on the development of germs. As a result of the cytological analysis, tetraploids and chimeras were revealed, which were obtained from the seeds from the open pollination of Orlik and Svezhest (treatment variants – 0,1% colchicines solution and 24 and 48 hours of exposition), as well as from the seeds obtained as a result of the Svezhest × Bolotovskoye crossing. Tetraploids had a normal growth but they differed in large leaves, while chimeras were of low size with normal leaves and internodes.

The Relationship

Essential thrombocythemia (ET) is a BCR-ABL1-negative myeloproliferative neoplasm associated with thrombotic and haemorrhagic complications. Reactive oxygen species (ROS) overexpression induces a growth advantage to JAK2V617F-positive clones and, in association with a higher number of immature platelets, leukocytosis, and additional cardiovascular risk factors, leads to an increased risk for thrombotic events. We evaluated oxidative stress by measuring ROS levels and the total antioxidant capacity (TAC) in 62 ET patients and investigated the relationship between oxidative stress, JAK2V617F mutational status and the development of thrombotic events. We found higher oxidative stress levels in JAK2V617F-positive vs. JAK2V617F-negative ET cases with no significant differences between homozygous and heterozygous genotypes. Increased ROS levels and thrombotic events were more frequent in ET patients with old age at diagnosis, higher haematocrit levels or leukocytosis.

The Relationship

: Mitochondria are potent source of cellular reactive oxygen species (ROS) and are vulnerable to oxidative damage. Mitochondria dysfunction could result in adenosine triphosphate (ATP) decrease and cell death. The kidney is an ATPconsuming organ, and the relationship between mitochondrial dysfunction and renal disease has been long noted. Mitochondrial targeting is a novel strategy for kidney diseases. At present, there are several ways to target mitochondria such as the addition of a triphenylphosphonium cation, mitochondria-targeted peptides, and nanocarrier. There are also a variety of choices for the payload, such as nitroxides, quinone derivates, vitamins and so on. This review summarized chemical and also clinical characteristics of various mitochondria-targeted antioxidants and focused on their application and perspectives in kidney diseases.
