Phakopsora pachyrhizi is an obligatory biotrophic fungus that causes Asian soybean rust (ASR) disease. ASR control primarily involves chemical control and the use of resistant soybean cultivars carrying an Rpp (resistance to P. pachyrhizi) gene. This study aimed to characterize the ASR resistance of three soybean Asian landraces. By screening the w...

Flowering time is an important agronomic trait, which is of great significance to the plant growth process. Salicylic acid (SA) is a key hormone that regulates plant growth and development. It can be converted into methyl salicylate (MeSA) catalyzed by SA carboxymethyl transferase (SAMT). Previous studies showed that SA was related to the regulatio...

The panicle erectness (PE) japonica cultivars have been widely planted in China. However, the relatively low yield level per plant and inferior eating and cooking quality of PE japonica cultivars are needed to improve further. In present study, a typical PE japonica cultivar, Nanjing 46, was selected as target for improving yield and grain quality ...

Grain size and shape are important for grain yield and quality in rice (Oryza sativa L.). Grain thickness (GT) is one of the constituent characteristics of grain shape and has a strong influence on grain weight in rice. In this study, a japonica cultivar (02428) with a thick grain phenotype was crossed with an indica cultivar (YZX) with a thin grai...

In common wheat, genes/QTL for a number of traits including grain quality and resistance against all the three rusts were pyramided in the background of an erstwhile elite Indian wheat cv. PBW343. For this purpose, two improved lines (P1 and P2) each in the background of PBW343 were crossed; these two lines were earlier developed using marker-assis...

Plant morphogenetic regulation is an important part of plant development biology. An ideal plant architecture can be created to allow plant to fully capture and use solar energy and maximize rice yields per unit area. The TCP (THEOSINTE BRANCHCHED1-CYCLOIDEA-PROLIFERATING CELL FACTOR1) family transcription factors participate in plant developmental...

Soil salinity is widespread in rice-producing areas globally, restricting both vegetative growth and grain yield. Improving salt tolerance of rice is a promising approach to meet the increasing food demand. An extensive literature survey indicates that maintaining proper Na+/K+ ratio and reactive oxygen species (ROS) content is the key issues for r...

Tobacco (Nicotiana tabacum L.) is an important agronomic crop and model system for studies of plant-pathogen interactions. Black shank, caused by Phytophthora nicotianae, is an important disease affecting tobacco production worldwide. In this study, a mapping population of 177 F7:8-9 recombinant inbred lines was generated from a cross between the h...

Rice false smut (RFS), caused by Ustilaginoidea virens, is one of the most destructive grain diseases in rice production worldwide. Hence, to increase the ability of rice resistance to U. virens is a major breeding goal of rice breeders. However, it is difficult to evaluate rice resistance to U. virens. Hence, to clarify the RFS-resistance genetic ...

Hybrid rice breeding offers an important strategy to improve rice production, and therefore is crucial for ensuring worldwide food security. Purity of hybrids is a key factor in keeping the high production of hybrid rice. While another important thing is mechanical weeding of hybrid rice, which could greatly release labor from laborious work and cu...
