The tomato (Solanum lycopersicum) male sterile 32 (ms32) mutant has been used in hybrid seed breeding programs largely because it produces no pollen and exserted stigmas. In this study, histological examination of anthers revealed dysfunctional tapetum development the ms32 mutant. locus was fine mapped to a 28.5 kb interval that encoded four putative genes. Solyc01g081100, homolog Arabidopsis bHLH10/89/90 rice EAT1, proposed be candidate gene MS32 contained single nucleotide polymorphism...
Broccoli (Brassica oleracea var. italica) is an important commercial vegetable crop. As part of efficient pollination system, cytoplasmic male sterility (CMS) has been widely used for broccoli hybrid production. Identifying the original sources CMS in accessions become breeding. In this study, diversity 39 accessions, including 19 lines and 20 hybrids, were analyzed using mitochondrial markers. All contained ogu orf138-related DNA fragment key genes nap CMS, pol tour not detected. The...
Internode length is an important agronomic trait affecting plant architecture and crop yield. However, few genes for internode elongation have been identified in tomato. In this study, we characterized elongated inbred line P502, which a natural mutant of the tomato cultivar 05T606. The P502 exhibits longer higher bioactive GA concentration compared with wild-type Genetic analysis suggested that controlled by quantitative loci (QTL). Then, major QTL on chromosome 2 based molecular markers...
Drought stress is a major abiotic factor affecting tomato production and fruit quality. However, the genes metabolites associated with responses to water deficiency rehydration are poorly characterized. To identify functional key metabolic pathways underlying drought recovery, drought-susceptible drought-tolerant inbred lines underwent transcriptomic metabolomic analyses. A total of 332 drought-responsive 491 rehydration-responsive core were robustly differentially expressed in both...
Abstract Leaf veins play an important role in plant growth and development, the bundle sheath (BS) is believed to greatly improve photosynthetic efficiency of C 4 plants. The OBV mutation tomato ( Solanum lycopersicum ) results dark has been used widely processing varieties. However, physiological performance difficulty explaining fitness production. In this study, we confirmed that was caused by both increased chlorophyll content absence extension (BSE) veins. Using genome-wide association...
Cultivated tomatoes are highly susceptible to the destructive parasite Phelipanche aegyptiaca. Wild relatives show potential resistance for genetic improvement. However, their and molecular mechanisms still unknown.Among 50 wild tomato accessions were evaluated P. aegyptiaca, most of exhibited varying degrees compared cultivars. Solanum pennellii LA0716 performed promising solid with very low infection by broomrape. The involved in was further confirmed cytological analysis, explored...
We previously discovered carpelloid stamens when breeding cytoplasmic male sterile lines in broccoli (Brassica oleracea var. italica). In this study, hybrids and multiple backcrosses were produced from different stamen sources maintainer lines. Carpelloid caused dysplasia of the flower structure led to hooked or coiled siliques with poor seed setting, which inherited a maternal fashion. Using four distinct twelve normal one maintainer, we used 21 mitochondrial simple sequence repeat (mtSSR)...
Late blight is a devastating tomato disease. Breeding new varieties with multiple resistance (R) genes highly effective for preventing late blight. The Ph-2 gene mediates to Phytophthora infestans race T 1 in tomato. In this study, we used an F 2 population derived from cross between Solanum lycopersicum Moboline (resistant) and LA3988 (susceptible) cultivars the fine mapping of Ph-2. Two flanking markers, CAPS-1 CC-Ase, mapped 141-kb genomic region containing 21 projected genes, 5 which...
Plant height is an important agronomic trait in crops. Several genes underlying tomato (Solanum lycopersicum) plant mutants have been cloned. However, few quantitative for identified tomato. In this study, seven loci (QTLs) controlling were Of which, qtph1.1 (QTL 1.1), qtph3.1 and qtph12.1 major QTLs explained 15, 16, 12% of phenotypic variation (R2), respectively. The was further mapped to 18.9-kb interval on chromosome 1. Based the annotated genome (version SL2.50, annotation ITAG2.40),...
Bud abortion is the main factor affecting hybrid seeds' yield during broccoli cross breeding when using ogura cytoplasmic male sterile (ogu CMS) lines. However, genes associated with bud are poorly understood. We applied RNA sequencing to analyze transcriptomes of normal and abortive buds maintainer ogu CMS Functional analysis showed that among 54,753 annotated unigenes obtained, 74 21 differentially expressed in common were upregulated downregulated compared buds, normal, respectively....
