and Conferred Resistance are Insufficient Against Tomato Yellow Leaf Curl Kanchanaburi Virus from Southeast Asia in Single or Mixed Infections of Tomato.

Tomato yellow leaf curl virus (TYLCV), a monopartite begomovirus that originated in the eastern Mediterranean, has spread worldwide, becoming a serious threat to tomato ( L.) production. Southeast Asia is considered one of the hotspots for begomovirus diversity, and a wide variety of local begomovirus species distinct from TYLCV have been identified.

Pepper yellow leaf curl Aceh virus: a novel bipartite begomovirus isolated from chili pepper, tomato, and tobacco plants in Indonesia.

During 2017, leaf samples of chili pepper (Capsicum annuum), tomato (Solanum lycopersicum), and tobacco (Nicotiana tabacum) plants exhibiting yellowing and curling symptoms were collected from Aceh province, Indonesia. These samples were used to isolate and sequence viral genomic DNA. Six isolates with complete DNA-A and DNA-B sequences of begomovirus were obtained, all of which showed >99% sequence identity to the others.

Marker-assisted breeding of Indonesia local rice variety Siputeh for semi-dwarf phonetype, good grain quality and disease resistance to bacterial blight.

Background: Rice is one of the most important staple food crops in Asia. Since the first green revolution beginning in 1960s, high-yield semidwarf modern rice varieties have been widely planted; however, traditional rice varieties with tall plant type are still grown in many countries due to their good grain quality and adaptation to local climate and environment. Siputeh, a local rice variety mainly planted in Java and Sumatra islands of Indonesia, produces long grain rice with good cooking and eating quality.
