Special Issue Information

Dear Colleagues,

Salt stress, drought stress, high temperatures, and low temperatures are major abiotic stressors that can severely limit plant growth, distribution, and crop yield. The study of plant genetics has major economic impacts: many staple crops are genetically modified to increase yields and provide resistance to stress. Transcription factors have the ability to respond to changes in the external environment by regulating their own expression and employing the spatiotemporal specificity of gene expression to activate target genes. Next-generation sequencing (NGS) technologies accelerate crop improvement methods by enabling the rapid and cost-effective sequencing of entire genomes and transcriptomes.

This Special Issue will address a selection of recent research topics and current review articles in the field of plant genomics and genetics. Bioinformatics papers, up-to-date review articles, and commentaries are also welcome. This Special Issue is supervised by Dr. Hengling Wei and assisted by our Guest Editor's Assistant Editor, Dr. Shoujiang Sun (China Agricultural University, Beijing, China).

Jatropha curcas L. is a shrub of the Euphorbiaceae family with non-toxic varieties found in Mexico that holds significant potential for biofuel production and other industrial applications. However, its limited in vitro regenerative capacity is a barrier to the development of productive species. Somatic embryogenesis (SE) offers a strategy to establish a regeneration system to overcome these challenges and enable genetic improvement. In this work, proteomic and gene expression analyses were utilized to identify key factors involved in SE induction in a non-toxic variety of J. curcas. Two-dimensional electrophoresis (2-DE) in combination with mass spectrometry was used to compare the proteomes of pre-globular and globular somatic embryos. RT-qPCR was used for gene expression analysis of the BBM, AGL15, SERK, IAA26 and eIF3f genes. The globular stage showed enrichment in the pathways related to carbohydrate and energy metabolism, protein folding, and stress response. In addition, the gene expression analysis of selected genes revealed a significantly elevated expression of BBM, AGL15, and IAA26 in globular embryos compared to pre-globular embryos. In contrast, SERK expression was low, and eIF3f expression remained unchanged between stages. These expression patterns may contribute to developmental arrest at the globular stage. These findings provide new insights into the molecular mechanisms regulating early SE in J. curcas and offer potential strategies for improving its propagation and industrial applications.

Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a destructive disease of wheat worldwide. William Som (WS), an Argentinian spring wheat landrace, has consistently exhibited high-level resistance to stripe rust for over 20 years in our field evaluations in Washington state, USA. A previous study showed high-temperature adult-plant (HTAP) resistance in WS. To map the HTAP resistance quantitative trait loci (QTL) in WS, 114 F5-8 recombinant inbred lines (RILs) from the cross AvS/WS were evaluated for their stripe rust response in seven field environments in Washington. The RILs and parents were genotyped with the Infinium 90K SNP chip. Four stable QTL, QYrWS.wgp-1BL on chromosome 1B (669–682 Mb), QyrWS.wgp-2AL on 2A (611–684 Mb), QyrWS.wgp-3AS on 3A (9–13 Mb), and QyrWS.wgp-3BL on 3B (476–535 Mb), were identified, and they explained 10.0–19.0%, 10.2–16.7%, 7.0–15.9%, and 12.0–27.8% of the phenotypic variation, respectively. The resistance in WS was found to be due to additive interactions of the four QTL. For each QTL, two Kompetitive allele-specific PCR (KASP) markers were developed, and these markers should facilitate the introgression of the HTAP resistance QTL into new wheat cultivars.
