Taking 1-year-old cuttings of a wild type and three cultivars of Rosa rugosa as test materials, this paper studied their biomass, photosynthesis, osmotic adjustment substance contents, root activity, and ion contents under the stress of different concentration NaCl. Salt stress inhibited the growth

BACKGROUND Rosa centifoliais commercially propagated by asexual means but in vitro propagation ensure the production of disease free and healthy plants and browning of explants creates hurdle in their multiplication. OBJECTIVE The aim was to reduce oxidative browning of shoots of R. centifolia in MS

Little is known about mechanisms of sweet briar adaptation to dry habitats. The species is highly invasive and displaces native plants from dry lands of the southern hemisphere. This study evaluates physiological basis of Rosa rubiginosa L. adaptation to soil drought. We performed a pot soil drought

A LEAFY-like gene was cloned in the long-day (LD) plant, Silene coeli-rosa (ScLFY). The open reading frame spans 1452 bp encoding a putative protein of 483 amino acids. Amino acid homology to other LFYs is 43-55%; conserved and variable regions were similar to others. However, an intron (808 bp) not

An investigation was conducted to assess proline anabolism and catabolism pathway genes under drought stress. Treatments were irrigation in three levels (25, 50 and 100% field capacity) at 1, 3, 6 and 12 d and two rose species (Rosa canina L. and Rosa damascene Mill.). The results showed that the

Micropropagated rose plants (Rosa hybrida L., cv. New Dawn) were inoculated with the arbuscular mycorrhizal (AM) fungus Glomus intraradices (Schenk and Smith) and subjected to different drought regimens. The dual objectives of these experiments were to investigate the mechanism and the extent to

There exist differences in the heat tolerance of Chinese rose varieties, and high temperature in summer can lead to failure of blooming in non-heat-tolerant Chinese rose varieties. We cloned a heat shock protein 70 gene (designated RcHSP70) from heat-tolerant varieties of Chinese rose (Rosa hybrida

Most endemic plant species have limited altitudinal ranges. At higher altitudes, they are subjected to various environmental stresses. However, these plants use unique defense mechanisms at high altitudes as a convenient survival strategy. The changes in antioxidant defense system and accumulation

Human and monkey prothymosin alpha contain activated carbonyl groups on glutamic acid residues. Three lines of evidence indicate the existence of unusual phosphates. 1) Prothymosin alpha continued to be metabolically labeled with [32P]orthophosphoric acid despite a mutation at Ser1, the sole site of
