Fusarium wilt disease is one of the major diseases causing a decline in watermelon yield and quality. Researches have informed that phytohormones play essential roles in regulating plants growth, development, and stress defendants. However, the molecular mechanism of salicylic acid (SA), jasmonic acid (JA), and abscisic acid (ABA) in resistance to watermelon Fusarium wilt remains unknown. In this experiment, we established the SA, JA, and ABA determination system in watermelon roots, and analyzed their roles in against watermelon Fusarium wilt compared to the resistant and susceptible varieties using transcriptome sequencing and RT-qPCR. Our results revealed that the up-regulated expression of Cla97C09G174770, Cla97C05G089520, Cla97C05G081210, Cla97C04G071000, and Cla97C10G198890 genes in resistant variety were key factors against (Fusarium oxysporum f. sp. Niveum) FON infection at 7 dpi. Additionally, there might be crosstalk between SA, JA, and ABA, caused by those differentially expressed (non-pathogen-related) NPRs, (Jasmonate-resistant) JAR, and (Pyrabactin resistance 1-like) PYLs genes, to trigger the plant immune system against FON infection. Overall, our results provide a theoretical basis for watermelon resistance breeding, in which phytohormones participate.

ABSTRACTThe role of Trichocompost and KCl fertilizer to control Fusarium wilt disease on onion in sandy soil. Fusarium wilt on onion is an interesting disease it is can loss the onion yield. The purpose of research to study trichocompost and KCl fertilizer role to control Fusarium wilt disease on ann onion. The research design used a Factorial Randomized Block Design with 2 factors. The first factor is 4 levels trichocompost, it is: without trichocompost (T0), trichocompost 10 t.ha-1 dosage (T1), trichocompost 20 t.ha-1 dosage (T2), trichocompost 30 t.ha-1 dosage (T3). The second factor is 3 levels KCl fertilizer, it is: without KCl (K0), KCl 100 kg.ha-1 dosage (K1), KCl 200 kg.ha-1 dosage (K2). Result of this research showed the application of trichocompost 10 t.ha-1 dosage and KCl 100 kg.ha-1 dosage can inhibit Fusarium wilt incubation time, can inhibit the patogen development with effective value 89,23%, the single factor it is aplication trichocompost 10 t.ha-1 dosage and trichocompost 30 t.ha-1 dosage not significant to dried onion bulb weight per clump of onion plant.Key words: Trichocompost, KCl fertilizer, Fusarium wilt disease, onion, sandy soil.ABSTRAKPenyakit layu Fusarium merupakan salah satu penyakit penting dapat menurunkan produksi bawang merah hingga 50%. Tujuan penelitian untuk mengetahui peranan trichokompos dan pupuk KCl dalam mengendalikan penyakit layu fusarium pada tanaman bawang merah. Penelitian menggunakan Rancangan Acak Kelompok faktorial dua faktor perlakuan. Faktor pertama 4 taraf dosis trichokompos yaitu: tanpa trichokompos (T0), trichokompos dosis 10 t.ha-1 (T1), trichokompos dosis 20 t.ha-1 (T2), trichokompos dosis 30 t.ha-1 (T3). Faktor kedua 3 taraf dosis pupuk KCl yaitu: tanpa pupuk KCl (K0), pupuk KCl dosis 100 KCl kg.ha-1 (K1), pupuk KCl dosis 200 KCl kg.ha-1 (K2). Hasil penelitian menunjukkan pemberian trichokompos 10 t.ha-1 dan pupuk KCl 100 kg.ha-1 dapat memperpanjang masa inkubasi penyakit, menekan serangan penyakit layu Fusarium dengan nilai efektivitas sangat baik (89,23%), perlakuan tunggal trichokompos dosis 10 t.ha-1 tidak berbeda nyata dengan dosis 30 t.ha-1 terhadap bobot umbi kering per rumpun tanaman bawang merah.Kata kunci: penyakit layu Fusarium, pupuk KCl, tanah berpasir, tanaman bawang merah, trichokompos.

<p><strong>Evaluation on the resistance of kenaf accessions (Hibis¬ cus cannabinus /..) to Fusarium oxysporum Schlect</strong></p><p>Resistant variety is one of the most important components controlling of fusarium wilt disease on kenaf caused by Fusarium oxysporum Schlect. To ind out resistant variety an evaluation on kenaf accessions was conducted in the laboratory and screen house of Phytopathology, RITFC, Malang in June-December 1997. The results of the selection on 77 accessions showed that 41 accessions were highly resistant, 1 2 accessions were resistant, 7 accessions were moderate, 12 accessions were susceptible, and 5 accessions were highly susceptible Three resistant and highly resistant accessions were namely 85-9-73, DS/005 H, and FJ/004 He could inhibit F. oxysporum growth about 23.40- 32.43 mm and its discolorisation about 0.0-13.4%.</p>

Tools And Techniques

Chickpea (Cicer arietinum L.) is one of the important annual legume crops, cultivated throughout the India since ancient time. It is also grown in many countries of the world. The crop has been facing numerous biotic and abiotic constraints. Among biotic constraint crop affected adversely by diseases, caused by many pathogens. Ever since 1918 when for the first time wilt disease of chickpea was reported and Fusarium oxysporum f. sp. ciceri was the causal organism many strategies have been adopted to control the wilt disease. The controlling methods included conventional as well as modern one. However, more and more emphasis was given on biological control agents such as AM fungi and Trichoderma. The role of AM fungi have been evaluated for controlling the wilt disease similarly role of Trichoderma is thoroughly established biological control agent against Fusarium wilt. With the advent of modern tools and techniques developing markers, resistant varieties, all such sources enable us to reduce the effect of pathogens. Here an attempted has been made to acknowledge the trend of disease management and evaluation strategies of Fusarium wilt of chickpea for getting better yields of the crop.

Late Stages

Pituitary Tumor Transforming Gene (PTTG) of human is known as a checkpoint gene in the middle and late stages of mitosis, and is also a proto-oncogene that promotes cell cycle progression. In the nucleus, PTTG works as securin in controlling the mid-term segregation of sister chromatids. Overexpression of PTTG, entering the nucleus with the help of PBF in pituitary adenomas, participates in the regulation of cell cycle, interferes with DNA repair, induces genetic instability, transactivates FGF-2 and VEGF and promotes angiogenesis and tumor invasion. Simultaneously, overexpression of PTTG induces tumor cell senescence through the DNA damage pathway, making pituitary adenoma possessing the potential self-limiting ability. To elucidate the mechanism of PTTG in the regulation of pituitary adenomas, we focus on both the positive and negative function of PTTG and find out key factors interacted with PTTG in pituitary adenomas. Furthermore, we discuss other possible mechanisms correlate with PTTG in pituitary adenoma initiation and development and the potential value of PTTG in clinical treatment.
