Combined Transcriptome- and Proteome-based Analyses for Mining of Genes Associated with Fruit Cracking in Chinese Jujube (Ziziphus jujuba Mill.)

Fruit cracking is a common physiological disorder in many fruit species. Jujube (Ziziphus jujuba Mill.) is an economically valuable fruit in which fruit cracking seriously affects fruit yield and quality and causes significant economic losses. To elucidate cracking-related molecular mechanisms, the cracking-susceptible cultivars ‘Cuizaohong’ and ‘Jinsixiaozao’ and the cracking-resistant cultivar ‘Muzao’ were selected, and comparative transcriptome analyses of cracking and non-cracking ‘Cuizaohong’ (CC and NC), cracking and non-cracking ‘Jinsixiaozao’ (CJ and NJ), and non-cracking ‘Muzao’ (NM) were conducted. A total of 131 differentially expressed genes (DEGs) were common to the CC vs. NC and CJ vs. NJ comparisons. To avoid passive processes after fruit cracking, we also mainly focused on the 225 gradually downregulated DEGs in the CJ, NJ, and NM samples. The functional annotation of the candidate DEGs revealed that 61 genes related to calcium, the cell wall, the cuticle structure, hormone metabolism, starch/sucrose metabolism, transcription factors, and water transport were highly expressed in cracking fruits. We propose that expression-level changes in these genes might increase the turgor pressure and weaken mechanical properties, ultimately leading to jujube fruit cracking. These results may serve as a rich genetic resource for future investigations on fruit cracking mechanisms in jujube and in other fruit species.

Ziziphus Jujuba

The Chinese jujube (Ziziphus jujuba Mill.), originating from China, with a history of over 4000 years, is one of the major fruit crops cultivated in China and on important areas in Central Asia, India, Iran, the Middle East etc. The high resistances to drought, salty soils and similar climate to that of China recommend this fruit tree as a valuable crop, especially in the context of climate changes and extended desertification. Chinese jujube has a high tolerance to pests and disease, being suitable for organic farming. The lack of divulgative papers on jujube true nutritional, medicinal and economic value, makes it still unknown for the great part of Romanian and European consumers, intensive advertising campaign is needed. The aim of this review is to highlight the requirements of the Chinese jujube (Ziziphus jujuba Mill.) in regards to the soil, water, climate as well as its high nutritional and medicinal values.

Abstract. The aim of this research was conducted to improve fruit set using different types of treatments and to find out the best treatment on the basis of number of fruits and pomological traits. For the research, ten years old 12 Lang cultivar of jujube trees and 3 seedlings from open pollinated of Ukraine genotypes were used. The tree spacing was 3.50×1.26 m. Spraying of Borax showed that average numbers of fruits were higher than the other treatments, average values of height, weight, width and thickness were also higher than the other treatments. On the other hand Urea and Girdling gave poor results in both years. In case of seedlings, different treatments for fruit setting have not given good results. Spraying with different treatments did not affect fruit-setting and pomological characteristics as well, in a larger scale. In 2006, bud breaking started in jujube cultivars on 28th April and in seedlings on 6th May. In 2007, bud breaking started in jujube cultivars 11 days earlier and 10 days earlier on 26th April in seedling. In jujube cultivars, there were some variations in the dates of flowering during 2006; the average date of flowering was 26th June in 2006 for all cultivars of jujube. In seedlings, flowering started on 6th July 2006. During 2007 flowering started in jujube cultivar jujube cultivars started flowering 12 days earlier and seedlings 22 days earlier. During 2006, fruit set started in jujube cultivars and seedlings, on 12th July and 14th July respectively. During 2007, fruit set started in jujube cultivars and seedlings on 1st July and 10th July respectively. In 2007 fruit set in jujube cultivars started 11 days earlier and in seedlings 4 days earlier. During 2006, ripening started in jujube cultivars and seedlings on 26th Sept. During 2007 ripening started in jujube cultivars and seedlings on 2nd and 10th Sep. respectively. In 2007, ripening started in jujube cultivars 24 days earlier and seedlings 16 days earlier. Statistical evaluations of the data showed the differences between 2006 and 2007.
