Kemampuan Indonesia dalam memenuhi kebutuhan beras nasional sangat penting. Akan tetapi, usaha pemenuhan kebutuhan beras ini tidak selamanya berjalan dengan lancar karena terganggunya produktivitas padi. Salah satu penyebab turunnya produktivitas padi di Indonesia karena adanya serangan serangga hama. Beberapa kendala yang menyebabkan gagalnya petani dalam mengendalikan serangga hama karena petani masih belum melakukan identifikasi serangga hama dan gejala serangan dengan baik. Penelitian yang dilaksanakan akhir tahun 2012 ini yang berlokasi di Lahan Persawahan Padi Dataran Tinggi Desa Sukawening, Kecamatan Ciwidey, Kabupaten Bandung, Jawa Barat bertujuan meng inventarisasi dan mendapatkan nilai keragaman jenis serangga hama pada tanaman padi. Penangkapan serangga hama yang dilakukan dengan menggunakan perangkap kuning, perangkap jaring dan perangkap cahaya. Hasil penangkapan serangga diidentifikasi di laboratorium. Indeks keragaman serangga dianalisis dengan menggunakan perhitungan Shannon- Weinner. Serangga hama yang dominan diperoleh pada fase vegetative yaitu Scirpophaga incertulas, Thaia oryzivora, dan Orselia oryzae. Serangga hama minor diperoleh yaitu Dicladispa armigera, Leptispa pygmaea, dan Melanitis ledaismene. Serangga hama yang dominan diperoleh pada fase generative yaitu Leptocorisa acuta, Scirpophaga incertulas, dan Thaiaoryzivora. Serangga hama minor diperoleh yaitu Nilaparvata lugens, Sogatella furcifera, dan Cofana spectra. Indeks keragaman serangga hama yang diperoleh pada ketiga lahan percobaan ada diantara sedang hingga tinggi.Pada fase vegetatif indeks keragaman tertinggi sebesar 4,74 pada pengamatan ke 6 dan terendah pada pengamatan ke 1 sebesar 2,22. Pada fase generatif indeks keragaman tertinggi pada pengamatan ke 9 sebesar 4,86 dan terendah pada pengamatan ke 12 sebesar 1,37.   Kata kunci :indeks keragaman, serangga hama, padi, Kabupaten Bandung.

Transcriptional Corepressors

Transcriptional regulation is a complex and pivotal process in living cells. HOS15 is a transcriptional corepressor. Although transcriptional repressors generally have been associated with inactive genes, increasing evidence indicates that, through poorly understood mechanisms, transcriptional corepressors also associate with actively transcribed genes. Here, we show that HOS15 is the substrate receptor for an SCF/CUL1 E3 ubiquitin ligase complex (SCFHOS15) that negatively regulates plant immunity by destabilizing transcriptional activation complexes containing NPR1 and associated transcriptional activators. In unchallenged conditions, HOS15 continuously eliminates NPR1 to prevent inappropriate defense gene expression. Upon defense activation, HOS15 preferentially associates with phosphorylated NPR1 to stimulate rapid degradation of transcriptionally active NPR1 and thus limit the extent of defense gene expression. Our findings indicate that HOS15-mediated ubiquitination and elimination of NPR1 produce effects contrary to those of CUL3-containing ubiquitin ligase that coactivate defense gene expression. Thus, HOS15 plays a key role in the dynamic regulation of pre- and postactivation host defense.
