Physiological and molecular responses of different rose ( L.) cultivars to elevated ozone levels.

The increasing ground-level ozone (O) pollution resulting from rapid global urbanization and industrialization has negative effects on many plants. Nonetheless, many gaps remain in our knowledge of how ornamental plants respond to O. Rose ( L.

Rosa1, a Transposable Element-Like Insertion, Produces Red Petal Coloration in Rose Through Altering Transcription.

Rose ( sp.) flowers have a rich diversity of colors resulting from the differential accumulation of anthocyanins, flavonols, and carotenoids. However, the genetic and molecular determinants of the red-petal trait in roses remains poorly understood.

Heterologous expression of Arabidopsis thaliana rty gene in strawberry (Fragaria × ananassa Duch.) improves drought tolerance.

Background: Strawberry (Fragaria × ananassa Duch.) is an important fruit crop worldwide. It was particularly sensitive to drought stress because of their fibrous and shallow root systems.

The control of red colour by a family of MYB transcription factors in octoploid strawberry (Fragaria × ananassa) fruits.

Octoploid strawberry (Fragaria × ananassa Duch.) is a model plant for research and one of the most important non-climacteric fruit crops throughout the world. The associations between regulatory networks and metabolite composition were explored for one of the most critical agricultural properties in octoploid strawberry, fruit colour.

Reinvigoration of diploid strawberry (Fragaria vesca) during adventitious shoot regeneration.

Diploid strawberry (Fragaria vesca 'Baiguo') is a model plant for studying functional genomics in Rosaceae. Adventitious shoot regeneration is essential for functional genomics by Agrobacterium tumefaciens-mediated transformation. An efficient shoot regeneration method using diploid strawberry leaf explants was conducted on 1/2MS + 1/2B medium that contained 2.

The R2R3 MYB transcription factor PavMYB10.1 involves in anthocyanin biosynthesis and determines fruit skin colour in sweet cherry (Prunus avium L.).

Sweet cherry is a diploid tree species and its fruit skin has rich colours from yellow to blush to dark red. The colour is closely related to anthocyanin biosynthesis and is mainly regulated at the transcriptional level by transcription factors that regulate the expression of multiple structural genes. However, the genetic and molecular bases of how these genes ultimately determine the fruit skin colour traits remain poorly understood.

Genetic features of the spontaneous self-compatible mutant, 'Jin Zhui' (Pyrus bretschneideri Rehd.).

'Jin Zhui' is a spontaneous self-compatible mutant of 'Ya Li' (Pyrus bretschneideri Rehd. S21S34 ), the latter displaying a typical S-RNase-based gametophytic self-incompatibility (GSI). The pollen-part mutation (PPM) of 'Jin Zhui' might be due to a natural mutation in the pollen-S gene (S34 haplotype).

Identification of a canonical SCF(SLF) complex involved in S-RNase-based self-incompatibility of Pyrus (Rosaceae).

S-RNase-based self-incompatibility (SI) is an intraspecific reproductive barrier to prevent self-fertilization found in many species of the Solanaceae, Plantaginaceae and Rosaceae. In this system, S-RNase and SLF/SFB (S-locus F-box) genes have been shown to control the pistil and pollen SI specificity, respectively. Recent studies have shown that the SLF functions as a substrate receptor of a SCF (Skp1/Cullin1/F-box)-type E3 ubiquitin ligase complex to target S-RNases in Solanaceae and Plantaginaceae, but its role in Rosaceae remains largely undefined.
