Abstract

Computer-based information systems have been widely applied in various fields of life including the education sector in terms of delivering accurate, relevant and timely, so as to produce quality information.Similarly, PP TPQ. Shirotul Fuqoha II that the development requires a system of information reporting the results of a web-based learning students that aims to display some information, especially about the daily value based on the achievements of students, in addition to the information received to be more rapid, accurate on time so that the learning outcomes of students pesetas learning activities can be monitored easily and accurately. Web-based information system is built using the programming language PHP with MySQL as the database and Mozilla Firefox as a browser. Keywords: Information Systems, The Learning Achievement, PP TPQ.

Abstract

Application of gene for gene hypothesis in breeding resistance to pests and disease should pay attention to genes and gene avirulen resistance of pathogens. The second aspect of  this  exploration  can  be  facilitated  by  molecular  breeding  technology.  In  addition, molecular marking can also be used to incorporate some resistance genes in an individual plant (gene pyramiding), a markup to the needs of cross-back (Marker Assisted Backcrossing), as well as experimental support for the detection of seed borne diseases. Rapid progress in the field of genomics has revealed some interesting phenomena about the genetics of microbes such as pathogenic effector, studies the genetic identity of an equality and diversity of microbial isolates that have not been explored. Better understanding of the mechanisms of pathogenicity and pathogen interaction between plants and will speed up the process of breeding for resistant plants. Keywords: Molecular Breeding, variability of pathogens, gene resistance

Abstract

Sarocladium oryzae and Fusarium spp. are the causal agents of sheath rot, a re-emerging rice disease that has recently gained importance in Indonesia and can cause yield losses of up to 85%. Both pathogens are seedborne, making their accurate identification and management essential. Conventional morphological identification is time-consuming and often inaccurate due to overlapping symptoms among fungal species. In this study, we demonstrated the seedborne transmission of sheath rot pathogens and provided novel insights by highlighting the predominance of F. equiseti and the detection of infections in asymptomatic seeds. A total of 75 fungal isolates were obtained from rice leaf sheaths, seeds, and harvested grains across CMS, inbred, and hybrid rice varieties. ITS rDNA sequencing identified 42 isolates as S. oryzae and 33 as Fusarium spp., including F. equiseti (29), F. incarnatum (1), and F. proliferatum (3). The detection of these pathogens in both pre-planting seed samples and post-harvest grains demonstrates their ability to spread through seeds. Importantly, their presence in asymptomatic seeds and grains indicates that routine visual inspection is insufficient for seed health monitoring.
