“…Among the identified candidate genes (Table 2), DUF581 (domain of unknown function-581 containing proteins) was reported to be a generic SnRK1 (Sucrose nonfermenting-1 (SNF1)-related protein kinase) interaction module and co-expressed with SnRK1 during plant cell signaling [93]. SnRK1 has also been suggested as a positive regulator of seed maturation and ABA signaling [95] and cell division [96]. In the same way, MFP1 (MAR-BINDING FILAMENT-LIKE PROTEIN 1, AT3G16000) was proposed to be involved in starch biosynthetic process in Arabidopsis [94].…”

In the current study, we used a linkage mapping–Genome-Wide Association Study (GWAS) joint strategy to investigate quantitative trait loci (QTLs) governing rice grain shape and weight in a doubled haploid (DH) population, using Kompetitive Allele-Specific PCR (KASP) markers. Results revealed the co-detection of the QTLs, qGLE-12-1 and qGLE-12-2 (Chromosome 12), qGTE-3-1 (Chromosome 3), and qGWL-5-1 and qLWRL-5-1 (Chromosome 5), associated with grain length, width, and length–width ratio, by both linkage mapping and GWAS. In addition, qGLL-7-1 (logarithm of the odds (LOD): 18.0, late-transplanted rice) and qGLE-3-1 (LOD: 8.1, early-transplanted rice), and qLWRL-7-1 (LOD: 34.5), detected only by linkage mapping, recorded a high phenotypic variation explained (PVE) of 32.5%, 19.3%, and 37.7% for grain length, and grain length–width ratio, respectively, contributed by the allele from 93-11. Meanwhile, qGWL-5-1 (LOD: 17.2) recorded a high PVE (31.7%) for grain width, and the allele from Milyang352 contributed to the observed phenotypic variation. Furthermore, qGTL-5-1 (LOD: 21.9) had a high PVE (23.3%) for grain thickness. Similarly, qTGWE-5-1 (LOD: 8.6) showed a high contribution to the PVE for grain weight (23.4%). Moreover, QTLs, qGW-5-1, qGT-5-1, qLWR-5-1, and qTGW-5-1 coincided on chromosome 5, flanked with KJ05_17 and KJ05_13 markers. Therefore, these QTLs are suggested to govern rice grain shape and weight. Additionally, the identified candidate genes could play active roles in the regulation of rice grain shape and weight, regarding their predicted functions, and similarity with previously reported genes. Downstream breeding and functional studies are required to elucidate the roles of these candidate genes in the regulation of grain shape and weight in rice.

In order to better understand the molecular mechanisms associated with salinity tolerance, transcriptome analysis of a local salt-tolerant wheat landrace (i.e. Roshan) was performed under salt stress. Transcriptome sequencing yielded 137,508,542 clean reads using the Illumina HiSeq 2000 platform. The results of two alignment programs, i.e. STAR and HISAT2, were used separately to perform the analysis of differentially expressed genes (DEGs) using DESeq2. Finally, a total of 17,897 DEGs were identified by DESeq2. Moreover, gene ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses identified 108 GO terms and 62 significant KEGG pathways, of which ‘metabolic process’ and ‘metabolic pathways’ were the most abundant enriched term and pathway, respectively. Additionally, key salinity-tolerant genes, including asparagine synthetase, were also identified in the present study. Out of 87 identified families of transcription factors, GAI‐RGA ‐ and ‐SCR (GRAS) was one of the most important, which participates in signal transduction, and meristem maintenance and development. Eventually, to validate the gene expression levels, six DEGs were selected for a quantitative real-time polymerase chain reaction, and the results were in line with those of RNA-Seq. The findings of the current study can guide future genetic and molecular studies and allow a better understanding and improvement of salt tolerance in wheat.

Most vegetative axes remain quiescent as dormant axillary buds until metabolic and hormonal signals, driven by environmental changes, trigger bud outgrowth. While the resumption of growth activity is well documented, the establishment and maintenance of quiescence is comparatively poorly understood, despite its major importance in the adaptation of plants to the seasonal cycle or in the establishment of their shape. Here, using the rosebush Rosa hybrida ‘Radrazz’ as plant model, we highlighted that the quiescent state was the consequence of an internal and active energy control of buds, under the influence of hormonal factors previously identified in the bud outgrowth process. We found that the quiescent state in the non-growing vegetative axis of dormant axillary buds displayed a low energy state along with a high expression of the ALTERNATIVE OXIDASE 2 (AOX2) and the accumulation of the corresponding protein. Conversely, AOX2 expression and protein amount strongly decreased during bud burst as energy status shifted to a high state, allowing growth. Since AOX2 can deviate electrons from the cytochrome pathway in the mitochondrial respiratory chain, it could drastically reduce the formation of ATP, which would result in a low energy status unfavorable for growth activities. We provided evidence that the presence/absence of AOX2 in quiescent/growing vegetative axes of buds was under hormonal control, and thus may constitute the mechanistic basis of both quiescence and sink strength manifestation, two important aspects of bud-break.
