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.

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.

Molecular cytogenetic analyses using fluorescence in situ hybridization (FISH) and genomic in situ hybridization (GISH) were carried out to elucidate inter-specific relationships among wild Lilium species distributed in Korea. FISH revealed four to eight 45S rRNA gene loci, which are located on chromosomes 1-7, 10, and 11 among the different species. In contrast, the 5S rRNA gene locus was conserved on the long arm of chromosome 3, occasionally with two adjacent sites on the same chromosome arm in a few species. The 5S rDNA site was located adjacent to the 45S rDNA site in only three species, Lilium distichum, Lilium hansonii, and Lilium tsingtauense. GISH analysis using genomic DNA probes detected strong hybridization of genomes between diploid and triploid Lilium lancifolium species, demonstrating that triploid plants were derived from diploid L. lancifolium and not from Lilium maximowiczii. Phylogenetic analysis of the ITS and NTS sequences supported the cytogenetic data as well as Comber's classification of the genus Lilium.

<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>

<P>A novel and facile regioselective synthesis of furan-3-carboxamides by a silver(i)/base-promoted reaction of propargyl alcohol with 3-oxo amides has been demonstrated. This one-pot protocol provides a rapid synthetic approach to diverse trisubstituted furan-3-carboxamides <I>via</I> cascade nucleophilic addition, intramolecular cyclization, elimination, and isomerization reactions. Employing a substituted propargyl alcohol, (<I>Z</I>)-enaminones have been obtained with high stereoselectivities by a Ag2CO3-promoted reaction starting from 3-oxo amides <I>via</I> C-N bond cleavage.</P>
