Snake melon is an important cucurbit crop especially in the Southeastern and the Mediterranean region of Turkey. It is consumed as fresh or pickled. The production is mainly done with the local landraces in the country. Turkey is one of the secondary diversification centers of melon and possesses valuable genetic resources which have different morphological characteristics in case of snake melon. Genetic diversity of snake melon genotypes collected from different regions of Turkey and reference genotypes obtained from World Melon Gene Bank in Avignon-France was examined using 13 simple sequence repeat (SSR) markers. A total of 69 alleles were detected, with an average of 5.31 alleles per locus. The polymorphism information content of SSR markers ranged from 0.19 to 0.57 (average 0.38). Based on cluster analysis, two major groups were defined. The first major group included only one accession (61), while the rest of all accessions grouped in the second major group and separated into different sub-clusters. Based on SSR markers, cluster analysis indicated that considerably high genetic variability exists among the examined accessions; however, Turkish snake melon accessions were grouped together with the reference snake melon accessions.

Article Synopsis
- - Zucchini tigre mosaic virus (ZTMV) is a positive-sense RNA virus from the Potyvirus genus, which infects various plants like snake gourd and zucchini.
- - Researchers created a full-length infectious cDNA clone of ZTMV to study its infection capabilities and sequenced its genome, finding a close genetic relation to the ZTMV-TW strain.
- - Analysis of 12 ZTMV isolates revealed high variability in the P1 gene, with overall negative selection on all genes but some positive selection at certain sites within the P1 gene itself.
Fine mapping of TFL, a major gene regulating fruit length in snake gourd (Trichosanthes anguina L).

Fruit length is a crucial agronomic trait of snake gourd (Trichosanthes anguina L); however, genes associated with fruit length have not been characterised. In this study, F snake gourd populations were generated by crossing the inbred lines, S and S (fruit lengths: 110 and 20 cm, respectively). Subsequently, bulk segregant analysis, sequencing, and fine-mapping were performed on the F population to identify target genes.

The plant (Cucurbitaceae), popularly known as bitter melon, snake fruit, Saint Vincent's herb, or little melon, is an African species that has developed in tropical and subtropical biomes in various parts of Brazil. The fruit is used in various traditional medicinal applications. The study aimed to identify the compounds of the essential oil of the leaves obtained by hydrodistillation and in the fruit through Solid-Phase Microextraction by headspace mode (HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS).

Article Synopsis
- - The Mongolian snake gourd, a valuable herbal medicine in China, is facing a serious root rot issue on a 20-ha farm in Zhenjiang City, leading to a 70% disease incidence and a 50% reduction in production as of 2021-2022.
- - Symptoms of the disease include yellow mottling on new leaves, wilting of upper leaves, and browning at the base of the stem, eventually causing the plants to die.
- - Researchers isolated a specific fungus from infected plants, leading to the identification of a representative strain for further analysis, revealing distinct conidial features that could help in understanding the disease.
