Tolerance Potential of Selected Genotypes of Zea mays L. and Pennisetum glaucum (L.) R. Br. under Drought Stress | Chapter 01 | Modern Research in Botany Vol. 1

Three genotypes of Pennisetum glaucum (IP14599, IP14787and LRNO3) and Zea mays (DTSYN11, LRNO1 and LRIO1) were screened at specified periods of drought stress and evaluated to detect trait signals for drought tolerance. Specific responses were confirmed against drought among all the selected genotypes of both the species. Genotypes of P. glaucum showed high biomass production, increased tolerance index and high plant nutrient content during drought stress. Conversely, genotype DTSYN11 of Z. mays performed better than the LRNO1 and LRIO1 regarding the evaluated traits. Biochemical studies related to protein content, proline, MDA concentration and antioxidants (CAT, APX) accumulation in both the species highlighted that pearl millet genotypes are better adapted than maize under drought stress. The low concentration of MDA and high accumulation of antioxidant enzymes were observed during increased duration of stress, perhaps this provides some extent of osmotic protection and antioxidant defence modulation to the pearl millet genotypes, thus causing protection to the crop. This work explains the capacity of pearl millet related to the defence mechanism over the maize genotypes under drought condition. Hence, pearl millet would be of great relevance in breeding programmes for crop improvement and can serve as a valued reserve to explicate molecular strategies in manipulating drought tolerance to other susceptible crops.

Empowerment and Leader Member Exchange towards Organizational Citizenship Behavior Readiness among Government Workforce in Malaysia | Book Publisher International

  State agencies are among the most significant entities that represent the public's needs, and their programmes are essential to a state's and the nation's economic growth and development. State agencies have been rife by public concerns for years, as demonstrated by the Public Complaints Bureau, as problems of inefficiency in service quality and delivery have yet to meet the public's standards. With the support of 15 employees from state agencies on Malaysia's east coast, this study aims to achieve three targets. The first and second objectives are to investigate the ties between leader-member exchange (LMX) and OCB empowerment. The final aim is to define the most significant factors that affect OCB willingness. A total of 288 people took part in the survey, which was conducted using a cluster sampling process. The survey items had achieved the necessary reliability, according to the pilot test results, and some sub-dimensions were renamed after factor analysis.

The Utilization of Agro-Waste: A Nanobiotechnology Point of View | Chapter 10 | Recent Advances in Biological Research Vol. 5

Aims: To review the utilization of agro-waste in the eco-friendly synthesis of nanoparticles and their biomedical, catalytic and industrial applications. Study Design: A review. Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary. Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ t

Re-asserting Cultural Perspectives: Old People and New Ideas in Bole Butake’s Lake God and The Survivors and Sankie Maimo’s Succession in Sarkov | Chapter 10 | Perspectives of Arts and Social Studies Vol. 2

African cultures have undergone transformations from the colonial period to the present, often to the detriment of its cultural evolution and within the larger global community. As it were, colonial education subordinated African communalism and created in its place an anti-African spirit evident in the assimilation of western values. This did not only end up in a kind of cultural betrayal, but also posed as a serious threat to the dignity and identity of the people. Those who fall prey to this kind of cultural imperialism are the young people who are often irrationally carried away by western fashion and modes that they tend to neglect and/or forget their cultural ways of life as they join the race of “progress.” This situation has given rise to a conscious effort by creative writers to re-assert and protect African values while at the same time liberating themselves from the longstanding western effort at suppressing, controlling and dominating their thoughts particularly through n
