2C value

The Far Eastern weed Artemisia verlotiorum was formerly reported from Lebanon. However, for a number of reasons this record was questionable. In 2019, the genuine presence of this species was confirmed based on macromorphology and strengthened by assessing the somatic nuclear DNA content (genome size or 2C-value) of the Lebanese populations.

New derivatives of 2(3),9(10),16(17),23(24)-tetrakis-(6-methylpyridin-2-yloxy)phthalocyanine (Pc) (2b, 2c, and 2d) were synthesized and their structures were characterized by elemental analysis, IR, 1 H NMR, and high-resolution mass spectrometry. The spectral results were in line with the proposed structures. The photodegradation of Orange G (OG) dye in DMSO by the Pc derivatives was investigated. The compounds showed relatively high photodegradation rates that increased with increasing size of the central atoms.

A flow cytometric protocol amenable to the crop was standardized by comparing four buffer compositions, three sample sizes and four incubation periods for isolated nuclei using Pisium sativum cv. Citrad (2C=9.09pg) as an internal reference standard. The study revealed significant differences for 2C DNA content among the accessions ranging from 5.73pg to 6.25pg, with 8.79% difference. The mean 2C DNA content of tall accessions has6.07pg/2C and 5.89pg/2C in dwarfs, corresponding to 1C genome size of 2968.23 Mb and 2880.21Mb, respectively.

The 2C nuclear DNA contents of 40 common vetch (Vicia sativa L.) lines and cultivars were determined by using both safflower (Carthamus tinctorius L.) and barley (Hordeum vulgare L.) as internal reference standards in flow cytometry analysis and correlated with plant morphological characters and 1000-seed weight.
