Seed Priming with Poly-Gamma-Glutamic Acid (γ-PGA) Improves Rice Germination Performance under Drought Conditions
No full textDrought poses a significant threat to global food security, particularly impacting rice cultivation
during the germination stage. In this study, a soil-based system that utilizes soil moisture content
was used to simulate optimal and stress conditions to assess the effect of the specific seed priming
protocols on germination. Eleven rice varieties, representative of indica and japonica subspecies,
grown in different ecosystems and having diverse nutrient contents, were treated with water or
solutions of either poly-gamma-glutamic acid (γ-PGA) or denatured γ-PGA. Collected data regarding
germinability and stress indices revealed different drought sensitivity between japonica and indica
subspecies and genotype-specific responses to priming. Particularly, γ-PGA improved germination
of highly susceptible indica varieties whereas water soaking was more effective for the moderately
sensitive japonica varieties. Integrative analyses evidenced differences between biofortified and nonbiofortified
rice under γ-PGA treatment, suggesting a possible correlation between γ-PGA efficacy
and Zn/Fe seed content. These findings underline that priming strategies should be tailored based
on genotype and therefore this factor should be always taken under consideration for future works.
The current study provides relevant information for optimizing seed priming techniques to sustain
the development of drought-resilient crops as a sustainable strategy to address agricultural resilience
and safeguard food security amidst environmental challenges

Get PDFKonsep bentuk tugas akhir musik gereja disusun dengan menerapkan teologi kontekstual. Seluruh bagian dari liturgi baik lagu-lagu, bahasa, alat musik, tarian dan kostum menerapkan kekhasan budaya Papua.Untuk itu penulis mempelajari lagu-lagu dan tarian yang cocok untuk digunakan dalam ibadah.Berdasarkan pengetahuan ini maka penulis menentukan lagu dan tarian yang sesuai dengan tema ibadah.
Ibadah ini dilaksanakan pada 7 Februari 2015 di Manokwari dan menjadi bagian dari rangkaian peringatan hari ulang tahun masuknya Injil di tanah Papua. Dalam penyelenggaraan ibadah, jemaat menikmati dan ikut berpartisipasi baik dalam menyanyikan lagu dan menari bersama.
Penulis mengambil kesimpulan bahwa ibadah dengan konsep ini cocok diterapkan di komunitas Papua.Selain itu, ibadah ini dapat digunakan sebagai sebuah model alternatif untuk menjembatani dualisme keyakinan sebagian umat Kristen di Papua.This service is planned and conducted in the form of theological contextual worship. The liturgy of this worship consists of indigenous worship songs, native languages of Papua, musical instruments, traditional dances and traditional costumes that represent Papuan culture.
By using this form, the writer tries to apply songs and dances in the form of traditional worship that will be suitable in Church Worship for the people of Papua. Based on this knowledge, the writer will be able to choose songs and dances that will be applicable for this worship. In addition, the worship service was carried out on February 7th2015 in Manokwari and it became part of the ceremonial worship series of the Bible Evangelical Anniversary at Papua.
During the worship service, all congregations enjoyed and actively participated both in singing and in dancing. Accordingly, the writer concludes that this contextual worship service can be properly applied in church worship within Papuan community. In addition, this worship style can also be utilized as an alternate model of worship service that can be used to bind Christian people of Papua together

Mapping of quantytative trait loci for high iron ang zinc content in polished rice (Oryza sativa L) grain and some agronomic traits using simple sequence repeats markers
No full textIron and zinc deficiency occurred especially in the poor region of the world causing significant loss due to death, sickness, and decreasing productivity as and life quality. Genetically increasing the iron and zinc content of rice grains is an efficient and effective way to overcome the iron and zinc deficiency problem. Mapping of QTLs (Quantitative Trait Loci) controlling high iron and zinc content in polished rice grains to get markers for Molecular Assisted Breeding (MAS) is prospective to be done since iron and zinc content are quantitative traits that highly affected by environment and its measurement is still costly. Study on polished rice as ste state of people use for their consumption would give more applicable result and study on agronomic and yield related traits would be helpful to incorporate those traits in breeding activity. Simple Sequence Repeats (SSR) markers were used in this study

Get PDFYield and Zn content of biofortified rice genotypes in an Indonesian rice agro-ecosystem
No full textSusanto U, Barokah U, Hidayatullah A, Satoto, Swamy M. 2017. Yield and Zn content of biofortified rice genotypes in an Indonesian rice agro-ecosystem. Nusantara Bioscience 9: 288-294. Approximately one-third of the world's population suffer from Zn deficiency causing significant socio-economic losses as a result of stunting and compromised immune system function. One strategy to overcome the problem is by developing rice cultivars with high grain Zn content (Zn Rice) to improve dietary intake.This study reports the yield and Zn content of 22 rice genotypes developed at the International Rice Research Institute (IRRI) and the Indonesian Centre for Rice Research (ICRR).The experiment was conducted in the Cirebon district of West Java province during the 2013 wet season (2013WS). Yield and grain Zn content (using an XRF machine) were measured. Five lines demonstrated higher yield (ranging from 7.0 to 8.9 t/ha) than the check variety Ciherang (5.2 t/ha), but had similar grain Zn content to the check variety Ciherang (23.4 ppm), ranging from 19.0 to 24.8 ppm. On the other hand, seven lines had higher grain Zn content (ranging from 30.0 to 34.2 ppm) compared to Ciherang, and five of these lines had comparable yield to Ciherang. The selected lines had acceptable agronomic traits, and are suitable for further testing and utilization, in addition to providing a foundation for future improvement in the dual goals of increasing the yield and nutritional value of rice
