“…Petunia F1 hybrids lead the commercial offer of cultivars due to their superior vigour, uniformity, and performance (Ganga et al, 2011). A cost-efficient hybrid production system requires a reliable pollination control to avoid selffertilization of female plants.…”

Petunia is a very important ornamental plant with a broad range of flower colour and size, and most of the cultivars grown are propagated through seeds. Cytoplasmic male sterility (CMS) is a maternally inherited character determined by mitochondrial genes that results in impaired pollen development. The unique and well characterized male sterile cytoplasm in Petunia is a valuable resource for hybrids production because it prevents self-fertilization of mother plants and ensures the purity of F1s. Introgression of the male sterile cytoplasm in elite lines of Petunia is achieved following a backcross scheme and can be assisted using molecular markers associated to the trait of interest. The objective of this study was to develop a molecular marker to identify the male sterile cytoplasm of Petunia. A PCR-based marker amplifying a region of the mitochondrial CMS-associated urfS only in the male sterile plants was designed. Results showed differential PCR amplification of a ≈ 600 bp product in plants carrying male sterile cytoplasm in four Petunia species and their F1s and BC1 generations. A multiplex PCR reaction was subsequently set up, adding specific primers amplifying a ≈ 800 bp product from the conserved region trnT-trn-L of the chloroplast genome as a positive control in order to unambiguously identify the cytoplasm types as normal or sterile. A rapid, simple and precise molecular marker is now available for assisting breeding of F1 hybrids in Petunia.

Metabolome and transcriptome profiling unveil the mechanisms of light-induced anthocyanin synthesis in rabbiteye blueberry (vaccinium ashei: Reade)

Background Blueberry is one of the most important fruit crops worldwide. Anthocyanin is an important secondary metabolites that affects the appearance and nutritive quality of blueberries. However, few studies have focused on the molecular mechanism underlying anthocyanin accumulation induced by light intensity in blueberries. Results The metabolic analysis revealed that there were 134 significantly changed metabolites in the natural light compared to the control, and flavone, flavonol, and anthocyanins were the most significantly increased. Transcriptome analysis found 6 candidate genes for the anthocyanin synthesis pathway. Quantitative reverse transcription PCR (qRT-PCR) results confirmed changes in the expression levels of genes encoding metabolites involved in the flavonoid synthesis pathways. The flavonoid metabolic flux in the light intensity-treatment increased the accumulation of delphinidin-3-O-arabinoside compared to under the shading-treatment. Furthermore, we performed qRT-PCR analysis of anthocyanin biosynthesis genes and predicted that the gene of VcF3’5’H4 may be a candidate gene for anthocyanin accumulation and is highly expressed in light intensity-treated fruit. Through the co-expression analysis of transcription factors and anthocyanin synthesis pathway genes, we found that the VcbHLH004 gene may regulate VcF3’5’H4, and then we transformed VcbHLH004 heterologously into tomato to verify its function. Conclusion These results provide novel insights into light intensity regulation of blueberry anthocyanin accumulation and represent a valuable data set to guide future functional studies and blueberry breeding.

Petunia is an important and beautiful ornamental flowering plant, grown throughout the world for its beauty and attraction. Different Petunia hybrids have been developed by petunia growing countries of the world. The prescribed study was conducted to investigate the association of abscisic acid with seed yield and its contributing traits of petunia line. Data for different physiological, morphological and petunia seed yield traits was recorded, analyzed and interpreted for final inferences. From results it was showed that the petunia lines IAGS-P8, IAGS-P9 and IAGS-P11 performed well for most of the studied traits. It was shown from multivariate analysis techniques that stomata conductance, chlorophyll b contents, seed area, chlorophyll a contents, flower fresh mass, flowers per plant, seed mass and abscisic acid contributed higher to seed yield per plant in petunia. The abscisic acid contents showed positive and significant association and contribution towards seed yield of petunia genotypes. It was suggested that selection on the basis of abscisic acid may be useful to develop good seed yield per plant and large number of flowers per plant in petunia under stressful environmental conditions. Key words: petunia; multivariate analysis; heritability; genetic advantage; abscisic acid content; seed yield IZVLEČEK UPORABA MULTIVARIATNE ANALIZE ZA OCENITEV POVEZAVE MED VSEBNOSTJO ABSCIZINSKE KISLINE IN RAZLIČNIMI Z RASTJO POVEZANIMI FIZIOLOŠKIMI ZNAKI PRI PETUNIJIPetunija je pomembna in lepa okrasna rastlina, ki se goji širom po svetu zaradi lepote in privlačnosti. V številnih državah, kjer jo gojijo, so bili vzgojeni različni križanci. Pričujoča raziskava je bila opravljena z namenom preučiti povezavo med vsebnostjo abscizinske kisline in lastnostmi, povezanimi s pridelkom semena preučevanih linij petunij. Izmerjene so bile različne fiziološke in morfološke lastnosti, ki vplivajo na pridelek semen, analizirana in pojasnjena je bila njihova povezava. Izsledki so pokazali, da so se linije petunij IAGS-P8, IAGS-P9 in IAGS-P11 izkazale kot primerne za večino analiziranih lastnosti. Multivariatna analiza je pokazala, da so parametri kot so stomatarna prevodnost, vsebnost klorofila b in a, površina semen, sveža masa cvetov, število cvetov na rastlino, masa semen in vsebnost abscizinske kisline prispevali največ k večjemu pridelku semena na rastlino. Vsebnost abscizinske kisline je imela značilen pozitiven vpliv na pridelek semena vseh genotipov petunij. Zaradi tega se priporoča, da je izbor genotipov petunije na osnovi večje vsebnosti abscizinske kisline primeren za vzgojo rastlin z velikim pridelkom semena na rastlino in velikim številom cvetov v stresnih okoljskih razmerah.
