Dear Editor,Bread wheat(Triticum aestivum)is one of the most important food crops and provides approximately 20%of the food calories for human consumption.A 70%increase in wheat production is needed by 2050 to keep pace with the growing global population(International Wheat Genome Sequencing,2014).Developing superior cultivars is an efficient way to improve ***,conventional breeding is time consuming,as more than eight generations are needed to develop new plant *** doubled haploid(DH)technology,homozygous lines can be produced in only two generations,dramatically accelerating the breeding *** wheat,haploids can be obtained by cross pollination with corn pollen followed by embryo rescue(Laurie and Bennett,1988).In maize,haploids can be induced by haploid inducer lines derived from Stock6(Liu et al.,2022).The cloning of two genes that control haploid induction(HI)in maize,MATL/ZmPLA1/NLD and ZmDMP,paved the way for DH breeding in more crop species(Jacquier et al.,2020).Further studies have shown that loss of function of TaPLAs triggers wheat HI with an efficiency of 5.88%to 31.6%(Liu et al.,2020a,2020b);this would be a promising approach for establishing a new,simple,and more efficient DH breeding method in wheat.

Medicinal plants produce valuable compounds, but often at low concentrations. Genome editing could be used to increase the production of valuable secondary metabolites in medicinal plants. The clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein 9(Cas9) system has emerged as a simple, widely used method for gene editing in plants.

Cucumis melo is one of the most important fruit vegetables cultivated in tropical and temperate regions, as it is highly valued for the quality of its fruits. Traditionally, C. melo is considered to be divided into two subspecies according to ovary hairiness, i.e., subspecies melo （long hairs, distributed from India to Europe and in America） and subspecies agrestis （short hairs, in Eastern Asia from India to Japan and in Africa）. Today, the species comprises wild, feral and cultivated varieties, including sweet melons used for dessert and non-sweet ones consumed raw, pickled or cooked. The goal of this paper was to summarize melon genome sequencing and the genetic diversity studies from different references.

Tight control of the intracellular uracil level is believed to be important to reduce the occurrence of uracil incorporation into DNA. The pyrG gene ofAspergillus niduIans encodes orotidine 5＇-phosphate decarboxylase, which catalyzes the conversion of orotidine monophosphate （OMP） to uridine monophosphate （UMP）. In this study, we found that pyrG is critical for maintaining uracil at a low concentration in A. nidulans cells in the presence of exogenous uracil. Excess uracil and its derivatives had a stronger inhibitory effect on the growth of the pyrG89 mutant with defective OMP decarboxylase activity than on the growth of wild type, and induced sexual development in the pyrG89 mutant but not in wild type. Analysis of transcriptomic responses to excess uracil by digital gene expression profiling （DGE） revealed that genes related to sexual development were transcrip- tionally activated in the pyrG89 mutant but not in wild type. Quantitative analysis by HPLC showed that the cellular uracil level was 6.5 times higher in the pyrG89 mutant than in wild type in the presence of exogenous uracil. This study not only provides new information on uracil recycling and adaptation to excess uracil but also reveals the potential effects of OMP decarboxylase on fungal growth and development.
