Special Issue Information

Dear Colleagues,

Plant breeding faces the challenge of satisfying the increasing demand for vegetables at the global level by developing new cultivars with improved yields and enhanced quality, while making a more efficient use of resources (water, fertilizers, agrochemicals, energy) in a climate change scenario. Utilization of cultivated and wild genetic resources, application of developments resulting from advances in genomics, and gene editing, among other technologies, will help in the development of a new generation of vegetable crops cultivars adapted to the present and future challenges. Diversification and enhancement of neglected vegetables through breeding will contribute to reaching this demand. This Special Issue on vegetable crop breeding deals with the breeding of vegetable crops in a wide sense, including theoretical and practical advances ranging from the enhancement of cultivated and wild genetic resources to the application of new plant breeding technologies in vegetable crops breeding and development of new cultivars.

Knowledge of the reproductive biology of a species is fundamental in order to develop an efficient program of genetic improvement by hybridization. The viability of the pollen, anther dehiscence, receptivity of the stigma and the anthesis of 12 improved lines of Habanero pepper were studied to develop a cross-breeding program. Among the results, the greatest number of flowers in anthesis was quantified at 8:00 a.m. for most genotypes. The dehiscence of the anther differed significantly in stages evaluated, observing in flower buds 100% of the closed anthers. The receptivity was positive in all the stages evaluated (before, during and after anthesis) and in all the genotypes, the most outstanding being the genotype AKN-08, which presented 100% of receptivity in the three stages evaluated. The viability of the pollen varied among the different conservation times evaluated (0, 24 and 48 h) while the highest percentage of viability (80%) and the largest number of seeds per fruit (56) were obtained when recently collected pollen was used (0 time). These results will have an important repercussion on the improvement of the Habanero pepper by increasing the efficiency of the programs to obtain hybrids and/or improved varieties. Full article

Allene oxide cyclase (AOC, EC 5.3.99.6) catalyzes the most important step in the jasmonic acid (JA) biosynthetic pathway and mediates plant defense response to a wide range of biotic and abiotic stresses. In this study, two AOC genes were identified from watermelon. Sequence analysis revealed that each of ClAOC1 and ClAOC2 contained an allene oxide cyclase domain and comprised eight highly conserved β-strands, which are the typical characteristics of AOC proteins. Phylogenetic analysis showed that ClAOC1 and ClAOC2 were clustered together with AOCs from dicotyledon, with the closest relationships with JcAOC from Jatropha curcas and Ljaoc1 from Lotus japonicus. Different intron numbers were observed in ClAOC1 and ClAOC2, which may result in their functional divergence. qRT-PCR analysis revealed that ClAOC1 and ClAOC2 have specific and complex expression patterns in multiple organs and under hormone treatments. Both ClAOC1 and ClAOC2 displayed the highest transcriptional levels in stem apex and fruit and exhibited relatively lower expression in stem. JA, salicylic acid (SA), and ethylene (ET) could enhance the expression of ClAOC1 and ClAOC2, particularly that of ClAOC2. Red light could induce the expression of ClAOC2 in root-knot nematode infected leaf and root of watermelon, indicating that ClAOC2 might play a primary role in red light-induced resistance against root-knot nematodes through JA signal pathway. These findings provide important information for further research on AOC genes in watermelon. Full article

Bacterial wilt, caused by Ralstonia solanacearum, is highly diverse and the identification of new sources of resistance for the incorporation of multiple and complementary resistance genes in the same cultivar is the best strategy for durable and stable resistance. The objective of this study was to screen seven accessions of cultivated eggplant (Solanum melongena L.) and 40 accessions from 12 wild relatives for resistance to two virulent R. solanacearum strains (Pss97 and Pss2016; phylotype I, race 1, biovar 3). The resistant or moderately resistant accessions were further evaluated with Pss97 in a second trial under high temperatures (and also with Pss2016 for S. anguivi accession VI050346). The resistant control EG203 was resistant to Pss97, but only moderately resistant to Pss2016. One accession of S. sisymbriifolium (SIS1) and two accessions of S. torvum (TOR2 and TOR3) were resistant or moderately resistant to Pss97 in both trials. Solanum anguivi VI050346, S. incanum accession MM577, and S. sisymbriifolium (SIS1 and SIS2) were resistant to Pss2016 in the first trial. However, S. anguivi VI050346 was susceptible in the second trial. These results are important for breeding resistant rootstocks and cultivars that can be used to manage this endemic disease.
