“…The search for novel male sterility–fertility restoration systems that overcome transgenic issues is also underway. Reviews on the history and genetics of male sterility are already available [ 169 , 170 , 171 , 172 , 173 , 174 , 175 , 176 , 177 , 178 , 179 , 180 , 181 , 182 , 183 ]. Furthermore, research reports discussing both the genetic and molecular levels of different kinds of male sterilities (GMS, CMS, and CGMS) are available for tomato [ 184 , 185 , 186 ], brinjal [ 187 , 188 ], hot pepper and sweet pepper [ 189 , 190 , 191 , 192 , 193 , 194 , 195 , 196 , 197 , 198 ], okra [ 199 ], muskmelon [ 200 , 201 , 202 ], watermelon [ 203 , 204 ], radish [ 193 , 205 , 206 , 207 , 208 , 209 , 210 , 211 , 212 , 213 , 214 , 215 , 216 ,…”

“…Regarding Ms locus identification, marker-assisted selection made it possible with RFLP [ 223 ], CAPS [ 227 ], SCAR [ 262 ], SNPs [ 263 ], and other PCR-based markers [ 226 , 264 , 265 , 266 ]. Recently, new primers for the cytoplasm [ 225 , 267 ] and the Ms locus [ 264 , 265 ] are being utilized for the identification of the cytoplasm and the Ms locus [ 183 , 268 , 269 , 270 ]. Although they are reported to be in complete linkage disequilibrium with the Ms locus, new PCR markers linked to the Ms locus are still being reported.…”

To address the complex challenges faced by our planet such as rapidly changing climate patterns, food and nutritional insecurities, and the escalating world population, the development of hybrid vegetable crops is imperative. Vegetable hybrids could effectively mitigate the above-mentioned fundamental challenges in numerous countries. Utilizing genetic mechanisms to create hybrids not only reduces costs but also holds significant practical implications, particularly in streamlining hybrid seed production. These mechanisms encompass self-incompatibility (SI), male sterility, and gynoecism. The present comprehensive review is primarily focused on the elucidation of fundamental processes associated with floral characteristics, the genetic regulation of floral traits, pollen biology, and development. Specific attention is given to the mechanisms for masculinizing and feminizing cucurbits to facilitate hybrid seed production as well as the hybridization approaches used in the biofortification of vegetable crops. Furthermore, this review provides valuable insights into recent biotechnological advancements and their future utilization for developing the genetic systems of major vegetable crops.

“…The main advantage in the use of MS lines is the reduction of costs, time and energy related to these emasculation procedures (Colombo and Galmarini, 2017). For these reasons, MS lines have been developed in several species of economic interest (Abbas et al, 2021;Wang et al, 2023), particularly in horticultural crops and ornamental plants (Yamagishi and Bhat, 2014;Barcaccia et al, 2016;Khan and Isshiki, 2016;Jindal et al, 2019;Singh and Khar, 2021). MS exhibits, in most cases, Mendelian inheritance, which is controlled either by the coordinated action of nuclear and cytoplasmatic genes or exclusively by nuclear genes (Kaul, 1988).…”

Current insights and advances into plant male sterility: new precision breeding technology based on genome editing applications

et al. 2023

Plant male sterility (MS) represents the inability of the plant to generate functional anthers, pollen, or male gametes. Developing MS lines represents one of the most important challenges in plant breeding programs, since the establishment of MS lines is a major goal in F1 hybrid production. For these reasons, MS lines have been developed in several species of economic interest, particularly in horticultural crops and ornamental plants. Over the years, MS has been accomplished through many different techniques ranging from approaches based on cross-mediated conventional breeding methods, to advanced devices based on knowledge of genetics and genomics to the most advanced molecular technologies based on genome editing (GE). GE methods, in particular gene knockout mediated by CRISPR/Cas-related tools, have resulted in flexible and successful strategic ideas used to alter the function of key genes, regulating numerous biological processes including MS. These precision breeding technologies are less time-consuming and can accelerate the creation of new genetic variability with the accumulation of favorable alleles, able to dramatically change the biological process and resulting in a potential efficiency of cultivar development bypassing sexual crosses. The main goal of this manuscript is to provide a general overview of insights and advances into plant male sterility, focusing the attention on the recent new breeding GE-based applications capable of inducing MS by targeting specific nuclear genic loci. A summary of the mechanisms underlying the recent CRISPR technology and relative success applications are described for the main crop and ornamental species. The future challenges and new potential applications of CRISPR/Cas systems in MS mutant production and other potential opportunities will be discussed, as generating CRISPR-edited DNA-free by transient transformation system and transgenerational gene editing for introducing desirable alleles and for precision breeding strategies.

Relevance. Onion (Allium cepa L.) is a valuable and demanded vegetable crop, which occupies one of the leading places in terms of sown areas and gross yields among other vegetable crops of the genus Allium L. Onion is popular in folk and evidence-based medicine, widely used for the prevention and treatment of many diseases due to its rich biochemical composition and useful properties. As part of import substitution and achieving food security of the country, scientists of the Federal State Budgetary Scientific Institution «Federal Scientific Vegetable Center» (FSBSI FSVC) are working intensively to create new generation varieties and hybrids.Methodology. Various resources on the topic were selected, publications in scientific and industry journals and databases were studied, a review of works on onion selection (yield, species diversity in shape and color, maturity, shelf life, biochemical parameters, commercial and seed productivity, resistance to biotic and abiotic stresses), as well as useful properties for humans and use in medicine was made.Results. The analysis of works shows that the wide distribution in the Russian Federation have such varieties of selection of FSBSI FSVC, such as Myachkovskij 300, Cherni prince, Al'ba, Atas, Ampeks and others. In recent years, created a medium-maturing hybrid onion onion F1 Drakon with brown dry scales and a maximum yield of 391.0 c/ha, as well as transferred to the State variety trial winter variety Novator with brown dry scales. Propagation of demanded varieties and hybrids for both production cultivation and for use in household farms is underway.Conclusion. In order to conveyor onion production, it is necessary to create varieties and hybrids of different maturity groups, as well as to work on improving marketability, seed productivity and resistance to various stresses.
