Co-expression of SfGPX and SfGST in Nicotiana benthamiana and two Spiraea species further regulates their low-temperature tolerance mechanism.

Spiraea fritschiana (S. fritschiana) is widely cultivated in horticulture and exhibits strong cold tolerance. We identified both glutathione peroxidases (GPXs) and glutathione S-transferases (GSTs) as key proteins involved in the low-temperature response of S.

Correlation between pollen morphology, karyotype, floral pigments, and scent components and morphological classification of 15 species and hybrids of Syringa L.

In this paper, the pollen morphology characteristics, chromosome karyotype characteristics, floral pigments, and scents components of 15 species and hybrids of Syringa L. were obtained by means of scanning electron microscopy, root tips quash method, HPLC-MS, and GC-MS, and the 15 species and hybrids of Syringa L. were clustered separately with each index.
