Opis:
Criteria used for evaluating drought tolerance of wheat cultivars demanding more time and efforts are usually not efficient and conclusive. Present study was conducted to evaluate ABA sensitivity as a criterion for evaluating drought tolerance of wheat cultivars at an early stage. Ten cultivars of wheat were subjected to drought at 3-leaf stage to select the most sensitive and two tolerant cultivars using mortality rate. Tatara was found the most susceptible whereas GA-2002 and Chakwal-50 were the cultivars with maximum drought tolerance. These cultivars were used to study sensitivity to applied absicic acid (based on germination index and relative growth inhibition rate) and physiological responses (leaf water content, chlorophyll stability index, coefficient of relative inhibition and proline accumulation) under drought stress. Highest ABAsensitivity was recorded in GA-2002 and Chakwal-50 whereas Tatara manifested minimum sensitivity. ABAsensitivity corresponded to physiological indices of drought tolerance. Results show that ABA-sensitivity is an efficient criterion that can be used to evaluate drought tolerance of wheat cultivars at early stage.

Opis:
In order to understand the roles of abscisis acid in soybean exposed to UV-C radiation, soybean seedlings were exposed to UV-C radiation and ABA was applied. The chlorophyll content, active oxygen metabolism and flavonoids content of soybean seedlings were investigated. The present study revealed that UV-C radiation significantly attenuated the chlorophyll content and suppressed PSII activity. It was observed that the contents of H2O2, malondialdehyde and O2 - were markedly increased, and the activities of antioxidant enzymes such as superoxide dismutase, peroxidase and catalase were enhanced, so were the flavonoids content, whereas the seedling height and biomass were significantly reduced. ABA application improved the activities of superoxide dismutase, peroxidase, catalase and the contents of flavonoids, decreased the contents of H2O2, MDA and O2 -, and also increased the chlorophyll content and enhanced PSII performance, thus enhancing biomass accumulation. The results suggested that ABA alleviated UV-C damage to soybean seedlings by reducing ROS generation and enhancing antioxidase activity. The isoflavones daidzin and genistein were significantly responsive to UV-C.

Opis:
One of the major goals of linguistics is to delineate the possible range of variation across languages. Recent work has identified a surprising number of typological gaps in a variety of domains. In morphology, this includes stem suppletion, person pronoun syncretism, case syncretism, and noun stem allomorphy. In morphosyntax, only a small number of all conceivable Person Case Constraints and Gender Case Constraints are found. While various proposals have been put forward for each individual domain, few attempts have been made to give a unified explanation of the limited typology across all domains. This paper presents a novel account that deliberately abstracts away from the usual details of grammatical description in order to provide a domain-agnostic explanation of the limits of typological variation. This is achieved by combining prominence hierarchies, e.g. for person and case, with mappings from those hierarchies to the relevant output forms. As the mappings are required to be monotonic, only a fraction of all conceivable patterns can be instantiated.

Opis:
The speech by Linda Klein – immediate past president of the ABA – has been presented as opening remarks during Poland-US Conference on the Rule of Law in Warsaw on 24 June 2018. In her speech Klein stated that the rule of law is expressed by the vigorous and independent legal profession and judicial branch of government. Lawyers must take the lead as advocates for the rule of law. Principles of the rule of law must never, ever yield to any perceived or actual emergency of the moment. Independent legal profession cannot and must not bend to the will of government, that independent courts must not be influenced by public or political pressure, and that access to justice is assured for all, even for the least powerful. The most important responsibility organized bar in every nation is to promote these principles and oppose any efforts to erode them. The core principles of the legal profession articulate the fundamental missions and activities of bar associations the world over. As a global leader of the rule of law issues and the world’s largest voluntary bar association, the American Bar Association has consistently supported efforts to build a strong, cohesive global movement to promote these fundamental principles.

Opis:
This article analyses the sources of the Rebellion of Anōš Āzād, son of Xusrō Anōšīrvān. The truth of what happened during this important period of Iranian history may never be known. But historical sources have transmitted fragments of the story from various different perspectives – often in lacunary form. Reading the relevant sources together, and analysing them, allows us to determine why some sources are fragmentary or deliberately misleading. It is possible to infer why certain authors, such as Procopius and Dinawari, might have been motivated to suppress or distort certain details also.

Opis:
Seed dormancy is of particular importance in the cultivation of cereals, as it directly affects the quality of crop yield. If the dormancy period is too short, this may lead to pre-harvest sprouting, whereas a dormancy period that is too long may cause uneven germination; both of these scenarios are associated with economic losses. Most enzymes engaged in the metabolism of abscisic acid (ABA) have been identified, and significant progress has been made in understanding the role of this phytohormone in the induction and maintenance of dormancy, mainly as a result of research conducted in Arabi-dopsis. Much less is known about the metabolism and function of ABA in cereal grains, especially in relation to dormancy and germination. This review focuses on the regulation of ABA metabolism in dormant and non-dormant cereal grains, in both the dry state and upon imbibition. Moreover, this review describes the influence of factors such as after-ripening, light, temperature, nitric oxide, and reactive oxygen species (ROS) on the dormancy and germination of cereal grains. These factors, with the exception of ROS, appear to affect the level of dormancy and germination of grains through regulation of ABA metabolism.
