“…There has been a substantial number of studies on discovery and utilization of QTL in breeding (Groover et al 1994;Sewell et al 2000;Jermstad et al 2001;Emebiri et al 1997;Guimarães 2007). QTL mapping played a major role for dissecting the genetic basis of phenotypic variation in forest trees (Chagné et al 2003;Lerceteau et al 2000;Pot et al 2006). We have better understating of the effect of individual QTL on phenotype (variation explained) and their position in the genome (Neale and Savolainen 2004).…”

“…Many agriculturally important traits such as quality and quantity of yield, and some forms of disease resistance, are controlled by many genes and are known as quantitative traits. Early stage selection is highly desirable, especially in perennial species, so reports of QTL mapping for studying gene expression at different developmental stages are common (Wu et al 2000;Lercetau et al 2000;Yin et al 2003;Atienza et al 2003;Fanizza et al 2005;Rae et al 2008).…”

Identification of QTLs for alpha acid content and yield in hop (Humulus Lupulus L.)

Amplified fragment length polymorphism (AFLP) and microsatellite (SSR) markers were applied to a segregation population of 111 genotypes derived from a pseudo-testcross of hop (Humulus lupulus L.) in order to detect quantitative trait loci (QTLs) for alpha-acid content and yield traits. A total of 199 markers (150 AFLPs, 43 SSRs, one hypothetical sex marker, five chs genes) were located on the 20 linkage groups (LGs) of the maternal and paternal maps, covering 706 and 616 cM, respectively. Due to the presence of 16 common biparental SSR markers, homology of seven LGs between parental maps could be inferred. The progeny segregated quantitatively for alpha-acid content and yield determined in the years from 2002-2006. A total of 13 putative QTLs for alpha acid content, 13 for dry cone weight and 18 for harvest index were identified on the two maps across years.Possible homologies between the detected QTLs on the two maps as well as in different years were established for all three traits. The most promising QTL for alpha acid content was identified on LG03 flanked by two AFLP markers (E-ACC-M-CAA103F*/P-ACA-M-CAC412F). From 13.80 to 36.64% higher content of alpha acids than the averages obtained in different years was observed in plants having both flanking markers. The candidate region for further characterization of QTLs for yield traits was located on LG01 where the putative QTLs for harvest index were detected on both maps in each of the 5 years. The QTLs identified represent an important improvement in alpha acids MAS and the first step towards marker-assisted breeding for hop yield.

“…Scots pine is one of the most critical forest-forming conifers globally, accounting for approximately 39% of all boreal forests [ 33 ]. We obtained data on WOX4 and the ancient WOX genes expression distribution in P. sylvestris L. trunk tissues during a period of cambial growth.…”

WUSCHEL (WUS)-related homeobox (WOX) protein family members play important roles in the maintenance and proliferation of the stem cells in the cambium, the lateral meristem that forms all the wood structural elements. Most studies have examined the function of these genes in angiosperms, and very little was known about coniferous trees. Pine is one of the most critical forest-forming conifers globally, and in this research, we studied the distribution of WOX4, WOX13, and WOXG genes expression in Pinus sylvestris L. trunk tissues. Further, we considered the role of TDIF(CLE41/44)/TDR(PXY) signaling in regulating Scots pine cambial activity. The distribution of CLE41/44-PXY-WOXs gene expression in Scots pine trunk tissues was studied: (1) depending on the stage of ontogenesis (the first group of objects); and (2) depending on the stage of cambial growth (the second group of objects). The first group of objects is lingonberry pine forests of different ages (30-, 80-, and 180-year-old stands) in the middle taiga subzone. At the time of selection, all the trees of the studied groups were at the same seasonal stage of development: the formation of late phloem and early xylem was occurring in the trunk. The second group of objects is 40-year-old pine trees that were selected growing in the forest seed orchard. We took the trunk tissue samples on 27 May 2022, 21 June 2022, and 21 July 2022. We have indicated the spatial separation expressed of PsCLE41/44 and PsPXY in pine trunk tissues. PsCLE41/44 was differentially expressed in Fraction 1, including phloem cells and cambial zone. Maximum expression of the PsPXY gene occurred in Fraction 2, including differentiating xylem cells. The maximum expression of the PsCLE41/44 gene occurred on 27 May, when the number of cells in the cambial zone was the highest, and then it decreased to almost zero. The PsPXY gene transcript level increased from May to the end of July. We found that the highest transcript level of the PsWOX4 gene was during the period of active cell proliferation in the cambial zone, and also in the trees with the cambial age 63 years, which were characterized by the largest number of cell layers in the cambial zone. In this study, we have examined the expression profiles of genes belonging to the ancient clade (PsWOXG and PsWOX13) in stem tissues in Scots pine for the first time. We found that, in contrast to PsWOX4 (high expression that was observed during the period of active formation of early tracheids), the expression of genes of the ancient clade of the WOX genes was observed during the period of decreased cambial activity in the second half of the growing season. We found that PsWOX13 expression was shifted to Fraction 1 in most cases and increased from the phloem side, while PsWOXG expression was not clearly bound to a certain fraction. Based on the data, the role of the CLE41/44-PXY-WOX signaling module in regulating P. sylvestris cambial growth is discussed.
