It was reported in this article that the transgenic elite indica container line D297B containing snowdrop lectin (Galanthus nivalis agglutinin, GNA) gene gna was obtained by biolisties. PCR, Southern blotting and Western blotting indicated that the transgenes were integrated into the genome of D297B and expressed in transgenic plants. Analysis of protein activity showed that product of transgene had activity of agglutinin. Resistance of transgenic seeds to Hygromycin B suggested that the transgenes were integrated in a single locus and inherited according to the pattern of 3:1 in most of transgenic plants. In addition, the PCR analysis revealed that the insect-resistant gene gna and selective marker gene hpt were co-integrated and co-inherited.

Soybean is one of the most important oilseed crops, and its seed oil content directly determines the economic value and industrial applicability worldwide. However, how soybean seed oil accumulation is regulated remains less understood. Here, through RNA-seq analysis and screening for the interacting proteins of a positive oil regulator GmNFYA, we identified an AP2/ERF-type transcription factor GmERFA, which acts as a negative regulator of oil accumulation.

Abiotic and biotic stress significantly limit crop yields. However, most stress-tolerance genes identified to date provide resistance to either biotic or abiotic stress and inhibit normal plant growth, limiting their application in breeding. We identified the soybean (Glycine max) NAC transcription factor gene GmST2, which is induced by salt and Botrytis cinerea stresses.

Although leucine-rich repeat-containing G protein-coupled receptor 4 (LGR4) is abundantly expressed in the pancreas, it is currently unknown whether LGR4 impacts pancreatic endocrine cells. Here, a critical role of LGR4 is demonstrated in islet β cell mass using a group of transgenic mice with LGR4 deficiency. Knock-out of Lgr4 in the pancreas and islet β cells significantly reduced islet β cell mass, and subsequently impaired glucose metabolism upon the challenge of a high-fat diet.

The wax of sugarcane buds, especially alkanol, was correlated to sugarcane smut resistance in previous studies. Moreover, alkanol could induce smut teliospore germination. This study aimed to analyze wax-related genes in sugarcane buds.

Protoplast-based systems have been utilised in a wide variety of plant species to enable genome editing without chromosomal introgression of foreign DNA into plant genomes. DNA-free genome editing followed by protoplast regeneration allows elite cultivars to be edited without further genetic segregation, preserving their unique genetic composition and their regulatory status as non-transgenic. However, protoplast isolation presents a barrier to the development of advanced breeding technologies in raspberry and no protocol has been published for DNA-free genome editing in the species.
