Fusarium proliferatum is a component of the onion basal rot disease complex. We present an annotated F. proliferatum draft genome sequence, totaling 45.8 Mb in size, assembled into 597 contigs, with a predicted 15,418 genes. The genome contains 58 secondary metabolite clusters and homologs of the Fusarium oxysporum effector SIX2.

Growth Ability

Ginger is one of the spices and medicinal commodities which is cultivated in Indonesia. One of the obstacles encountered in the cultivation of ginger is the rhizome rot disease which is mainly caused by Fusarium oxysporum Schlecht f.sp. zingiberi Trujillo. This study is aimed to know the growth ability and virulence level of the isolates on ginger rhizome and plants. The research was conducted in the laboratory and in the screen house by using Complete Random Design consisted of 10 treatments and 4 replications. The parameters observed were growth ability of F. oxysporum f.sp. zingiberi, rhizome rot disease symptoms, incubation period, extensive decay and weight difference of the rhizomes. The results showed that F. oxysporum f.sp. zingiberi which was stored for 4 years in sterile soil medium was still capable to cause damage to the rhizome and plants. Incubation periods of rhizome decay and plant symptoms were from 3 to 11.5 and 55.5 to 68.5 days, respectively. The most virulent isolate was MSO1 with extensive decay of rhizome and the wilting intensity were 108.95 mm2 dan 33.88%, respectively. IntisariJahe merupakan salah satu komoditas rempah dan obat yang banyak dibudidayakan di Indonesia. Salah satu kendala yang dihadapi dalam budidaya jahe adalah adanya gangguan penyakit busuk rimpang yang disebabkan (terutama) oleh Fusarium oxysporum Schlecht f.sp. zingiberi Trujillo. Penelitian bertujuan untuk menguji daya tumbuh dan virulensi isolat F. oxysporum f.sp. zingiberi pada rimpang dan tanaman jahe gajah. Penelitian dilakukan di laboratorium dan di rumah kasa menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang masing-masing terdiri dari 10 perlakuan dan 4 ulangan. Parameter yang diamati meliputi daya tumbuh F. oxysporum f.sp. zingiberi, gejala penyakit busuk rimpang, masa inkubasi, luas pembusukan dan selisih bobot basah rimpang. Hasil penelitian menunjukkan bahwa F. oxysporum f.sp. zingiberi yang telah di simpan 4 tahun dalam medium tanah steril mampu menyebabkan kerusakan pada rimpang dan tanaman jahe. Masa inkubasi gejala busuk pada rimpang serta gejala pada tanaman masing- masing berkisar antara 3–11,5 serta 55,5–68,5 hari. Isolat yang paling virulen adalah MSO1 dengan nilai luas pembusukan pada rimpang dan intensitas penyakit masing-masing sebesar 108,95 mm2 dan 33,88%.

The yields of edible rhizome from the cultivation of the perennial hydrophyte lotus (Nelumbo nucifera) can be severely reduced by rhizome rot disease caused by Fusarium species. There is a lack of rapid field-applicable methods for detection of these pathogens on lotus plants displaying symptoms of rhizome-rot. Fusarium commune (91%) and Fusarium oxysporum (9%) were identified at different frequencies from lotus samples showing symptoms of rhizome-rot. As these two species can cause different severity of disease and their morphology is very similar, molecular-diagnostic based methods to detect these two species were developed. Based on the comparison of the mitochondrial genome of the two species, three specific DNA loci targets were found. The designed primer sets for conventional PCR, qPCR and loop-mediated isothermal amplification (LAMP) precisely distinguished the above two species when isolated from lotus and other plants. The LAMP detection limits were 10 pg/μl and 1 pg/μl of total DNA for F. commune and F. oxysporum, respectively. We also carried out field-mimicked experiments on lotus seedlings and rhizomes (including inoculated samples and field diseased samples), and the results indicated that the LAMP primer sets and the supporting portable methods are suitable for the rapid diagnosis of the lotus disease in the field. The LAMP-based detection method will aid in the rapid identification of whether F. oxysporum or F. commune are infecting lotus plants with symptoms of rhizome-rot, and can facilitate efficient pesticide use and prevent the disease spread through vegetative propagation of Fusarium-infected lotus rhizomes.

Fusarium oxysporum Schlecht. f.sp. radicis-lycopersici Jarvis & Schoemaker (FORL) is a saprophytic fungus, responsible for the fusarium crown and root rot disease in tomato (Solanum lycopersicum L.). This is one of the most destructive pathogens of this species. A new cleaved amplified polymorphic sequence (CAPS) marker C2-25 was developed for the detection of the dominant gene Frl, which confers tomato resistance to FORL. C2-25 was amplified from a conserved ortholog set II (COSII) sequence C2_At2g38025. The XapI-derived restriction product of 700 bp was informative for the identification of FORL resistant tomato genotypes and can be used as a diagnostic marker in tomato breeding programmes and hybrid seed production.
