Razia Sultana1,주호종,채종찬,김강민,이귀재 한국식물병리학회 2013 식물병연구 Vol.19 No.4

The popcorn disease caused by sclerotia forming fungi reduces the productivity of mulberry fruits in worldwide. In Korea, only two species (Ciboria shiraiana and Scleromitrula shiraiana) have been reported as themajor causal organisms and their morphological features are also largely unknown. Hereby, we report thefirst identification of another species (i.e. Ciboria carunculoides) in Korea and detailed features of theiranamorphic stage. Fungi dominantly associated with sclerotia were purely isolated from infected mulberryfruits under the microscope. PCR-amplified DNA encoding 5.8S rRNA displayed 100% similarity to Ciboriacarunculoides. The anamorphic features exhibited the absence of true mycelia. Instead, very short, aseptated,branched conidiophores were directly emerged from sclerotia. Phialides were usually three in number fromeach conidiophore, ampuliform to navicular in shape, slightly curved and tapering towards the apex. Conidiawere produced from phialides and mostly found as one celled, pear shaped, not hyaline with smooth touneven surface walled. Diversely modified features in phialides formed pseudo-mycelial structures aroundthe host tissue. Combined all, current study is the first report of C. carunculoides isolated in Korea and theforemost detailed description of its anamorph stage.

Arshiya Sultana,Fahmida Kousar,Shahzadi Sultana,Taseen Banu,Arfa Begum 셀메드 세포교정의약학회 2023 셀메드 (CellMed) Vol.13 No.14

Menopause is a physiological phase experienced by all women as part of normal aging known as menopause. Per se, menopause is not a disease, but hormonal imbalance may lead to menopausal symptoms in some women. The unani physician described that in Sinn-i-Inḥiṭāṭ/ Sinn al-Yās, Burūdat (coldness) increases lead to Ihtibās al-Tamth (amenorrhea) that can occur naturally. Besides, Khilt Dam (blood) production decreases from the liver, slight production occurs, tends towards Burūdat. Therefore, at this age, Ihtibās al-Tamth is associated with Alāmāt Sinn al-Yās (menopausal symptoms) including weight gain, loss of appetite, hirsutism, fatigue, headache, backache, arthralgia, neck pain, general myalgia, nervousness, anxiety, depression, and insomnia. The traditional Unani manuscripts are enriched with knowledge for the management of Alāmāt Sinn al-Yās. Consequently, an extensive exploration of classical texts concerning the management of Alāmāt Sinn al-Yās was undertaken. Moreover, PubMed, Scopus, Google Scholar, and other indexing databases were thoroughly explored for evidence-based approaches to managing menopausal symptoms. The principle management as per Unani texts is to treat the cause of Alāmāt Sinn al-Yās. Unani medicines with emmenagogue, anti-inflammatory, analgesic, cardioprotective, and neuroprotective properties are beneficial for the amelioration of Alāmāt Sinn al-Yās. Unani Herbs such as Asgandh, Aslusūs, Khārkhasak, Tagar, Shuneez, Ustukhuddus, Zafran, and M̒̒a̒̒jūn Najāh possess properties and are proven scientifically for their efficacy in Alāmāt Sinn al-Yās. Hence, the substantiation and preservation of traditional knowledge assume paramount importance in facilitating prospective research and proving invaluable in the modern era. Moreover, the conduct of randomized controlled trials, systematic reviews, and meta-analyses becomes imperative.

Sultana, Nasim,Lee, Nam-Ho Korean Chemical Society 2009 Bulletin of the Korean Chemical Society Vol.30 No.8

Bioactivity-guided fractionation led to the isolation of two new phenylpropanoids, 3-O-p-coumaroyl-1-(4-hydroxy- 3,5-dimethoxyphenyl)-1-propanone (1) and 3-O-p-coumaroyl-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-O-$\beta$-gulcopyranosylpropanol (2), together with three known compounds, N-p-coumaroylserotonin (3), N-feruloylserotonin (4) and p-coumaric acid (5) from the leaves of Sasa quelpaertensis Nakai. Their structures were elucidated by spectroscopic methods including 1D and 2D-NMR. Compared to arbutin (I$C_{50}$ 0.048 mM) as a control, compounds 3 and 4 exhibited stronger tyrosinase inhibition activities with an I$C_{50}$ values of 0.027 mM and 0.026 mM, respectively. Compounds 1 (I$C_{50}$ 0.055 mM) and 2 (I$C_{50}$ 0.053 mM) also showed strong activities.

Sultana, Sabiha,Adhikary, Sanjoy Kumar,Islam, Md. Monirul,Rahman, Sorder Mohammad Mahbubur The Korean Society of Plant Pathology 2018 Plant Pathology Journal Vol.34 No.2

Leaf blotch of wheat caused by Bipolaris sorokiniana is a major constraint to wheat production, causing significant yield reduction resulting in severe economic impact. The present study characterizes to determine and compare pathogenic variability exist/not based on components of leaf blotch disease development and level of aggressiveness due to agroclimatic condition of B. sorokiniana in wheat. A total of 169 virulent isolates of B. sorokiniana isolated from spot blotch infected leaf from different wheat growing agroclimate of Bangladesh. Pathogenic variability was investigated on a susceptible wheat variety 'kanchan' now in Bangladesh. A clear evidence of positive relationship among the components was recorded. From hierarchical cluster analysis five groups were originating among the isolates. It resolved that a large amount of pathogenic diversity exists in Bipolaris sorokiniana. Variation in aggressiveness was found among the isolates from different wheat growing areas. Most virulent isolates BS 24 and BS 33 belonging to High Ganges River Flood Plain agro-climatic zones considered by rice-wheat cropping pattern, hot and humid weather, high land and low organic matter content in soil. Positive relationship was found between pathogenic variability and aggressiveness with agro-climatic condition.

Sultana Jahan Ophra,Sameena Begum,Raihanul Islam,Md. Nazrul Islam 대한공간정보학회 2018 Spatial Information Research Vol.26 No.6

Bangladesh is a riverine country. Every year it faces many natural hazards due to river. Bangladesh is mainly formed by alluvial deposits. It faces riverbank erosion frequently due to regular shifting of river channels. This research work provides an overview of the trend of riverbank erosion of Padma River of Munshiganj, Madaripur and Shariatpur district. It also shows the land cover change due to riverbank erosion. The riverbank erosion was calculated by using remote sensing and geographic information systems (GIS) techniques. Only secondary data have been used to reach the research goals. Various computer software such as Erdas Imagine, Arc GIS, Google Earth, Environment for Visualizing Images etc. have been used to process and analyze raw data. In this study, using seven selected images of Landsat TM and OLI acquired from 1988 to 2017, the riverbank migration patterns and land dynamics of Padma resulted from accretion/ erosion processes for 29 years were investigated. The migration rates are based on the differences in 1988–1993, 1993–1998, 1998–2003, 2003–2008, 2008–2013 and 2013–2017. The average erosion and accretion rates are 1472.056 and 1610.152 ha/year of Padma, respectively. This study shows Padma got meandered and braided from almost straight channel in the time span.

Sultana, Hasina,Seo, Dongwon,Choi, Nu-Ri,Kim, Yeon-Su,Manjula, Prabuddha,Bhuiyan, Md. Shamsul Alam,Heo, Kang-Nyeong,Lee, Jun-Heon The Korean Society of Poultry Science 2017 韓國家禽學會誌 Vol.44 No.2

A total of 340 individuals from seven duck populations were studied using 24 polymorphic microsatellite (MS) markers to identify plumage colors with genetic diversity. The estimated average number of alleles (Na), polymorphic information content (PIC) value, and expected heterozygosity (He) per locus of all populations were 11.5, 0.602, and 0.635, respectively. The calculated population genetic distance (Fst), inbreeding coefficient of individuals within duck populations (Fis), and total inbreeding among populations (Fit) were 0.135, 0.105, and 0.229, respectively. Statistical analyses for each population using 24 marker combinations, revealed that the estimated average number of effective alleles (Ne), observed heterozygosity (Ho), and fixation index of inbreeding within populations (F) were 3.129, 0.505, and 0.104, respectively. The results of genetic distance and phylogenetic analysis revealed that Korean native duck populations were clearly separated from all Bangladeshi duck populations. Moreover, all populations clustered well according to their genetic distance, but could not be clearly separated according to black and white plumage colors or plumage color pattern. The combination of these 24 MS markers can be used for discrimination and determination of the genetic diversity of native duck breeds in further investigations for conservation and special development purposes.

The maternally inherited mitochondrial DNA (mtDNA) D-loop region is widely used for exploring genetic relationships and for investigating the origin of various animal species. Currently, domestic ducks play an important role in animal protein supply. In this study, partial mtDNA D-loop sequences were obtained from 145 samples belonging to six South-East Asian duck populations and commercial duck population. All these populations were closely related to the mallard duck (Anas platyrhynchos), as indicated by their mean overall genetic distance. Sixteen nucleotide substitutions were identified in sequence analyses allowing the distinction of 28 haplotypes. Around 42.76% of the duck sequences were classified as Hap_02, which completely matched with Anas platyrhynchos duck species. The neighbor-joining phylogenetic tree also revealed that South-East Asian duck populations were closely related to Anas platyrhynchos. Network profiles were also traced using the 28 haplotypes. Overall, results showed that those duck populations D-loop haplotypes were shared between several duck breeds from Korea and Bangladesh sub continental regions. Therefore, these results confirmed that South-East Asian domestic duck populations have been domesticated from Anas platyrhynchos duck as the maternal origins.

<i>Bacillus thuringiensis</i>C25 suppresses popcorn disease caused by<i>Ciboria shiraiana</i>in mulberry (<i>Morus australis</i>L.)

Sultana, Razia,Kim, Kangmin Informa UK (TaylorFrancis) 2016 Biocontrol science and technology Vol.26 No.2

<P>The mulberry tree is an important crop for silkworm farming and for the health care industry. In Asia, the annual productivity of mulberry fruits is greatly reduced due to popcorn disease mainly caused by Ciboria shiraiana, a sclerotia-forming fungal pathogen. To date, the development of efficient biocontrol agents (BCAs) against this disease has been hampered by the recalcitrance of C. shiraiana to in vitro culturing methods. Here, we established alternative in vitro antifungal assays that directly monitored the effects of BCAs on the growth of C. shiraiana apothecia and further reported that Bacillus thuringiensis C25 suppressed popcorn disease in field conditions. Initially, from mulberry drupelets showing the popcorn disease symptoms, we confirmed the infection of C. shiraiana and observed its morphology in asexual stage. Then, apothecia of C. shiraiana were induced from the sclerotia collected from the disease-infested orchard. Two bacterial isolates, Enterobacter sp. C5 and B. thuringiensis C25, strongly suppressed the elongation and fresh weight accumulation of apothecia stalks, the width of hymenium, and ascus and ascospore formation of C. shiraiana. In addition, both bacterial isolates degraded the ultrastructure of hymenium cells in C. shiraiana apothecia. Ultimately, treatment of mulberry trees with B. thuringiensis C25 mitigated the incidence of popcorn mulberry disease under field conditions. In conclusion, B. thuringiensis C25 is the first reported BCA shown to efficiently control mulberry popcorn disease. Our results also support that B. thuringiensis exerts diverse biocontrol roles in addition to insecticidal behaviour.</P>
