Lacking colourful perianths (petals and sepals) 2. Having florets comprised of glumes which are scales that protect the floret within a spikelet 3. Having linear leaves 4. Both are wind pollinated 5. Unlike most flowers (dicotyledons), grasses and sedges are monocotyledons – i.e. they have one seed leaf rather than two However, there are a number of differences in structure between sedges and grasses, some of the main ones are listed below. Sedges usually have: ¾ Triangular (or at least 3 point symmetry) and solid stems ¾ Leaf sheaths that are never split ¾ Flowers that are spirally arranged and appearing in 4 or 5 rows ¾ Flowers that are often unisexual, the plant bearing separate male and female inflorescence ¾ Flower spikelets with only one glume Grasses usually have: • Cylindrical or flattened, and hollow stems • Leaf sheaths that are split • Flowers and spikelets that are arranged in two diametrically opposite rows (distichously arranged) • Flowers that are bisexual • Flower spikelets with two glumes

I have .accession number in database..soon it will be published...but one thing is that...you shold do ...barcoding..of the taxa ,which is not in the database

A la pregunta de si es Liquen o briophyta, la respuesta es: A. compacta Phil, es una planta spermathophyta, dicotiledonea del orden apilaes, familia apiaceae. saludos Manuel Borrero Cedeño

Wish you all the best for your work. Please feel free to ask for any assistance in this very interesting, however quite difficult task.

I have published a book jointly with Dr. M S Dinesh (1989) entitled "The Embryology of Angiosperms: A Classified Bibliography (1965-1985)".

Is there any Project granted to u by DST

Thankyou sir. Sir , please send the link 2nd time for the followings 1) Plant salt tolerance (2001) 2) Effect of salinity on osmotic adjustment, glycinebetaine accumulation and the betaine aldehydeThankyou sir. Sir , please send the link 2nd time for the followings 1) Plant salt tolerance (2001) 2) Effect of salinity on osmotic adjustment, glycinebetaine accumulation and the betaine aldehyde dehydrogenase gene expression in two halophytic plants, Salicornia europaea and Suaeda maritima (2004) 3) Halophytic Forage Plants in Response to Irrigation with Diluted Seawater (2006) 4) Modern methods for counteracting salinity stress: A review (2006) 5)Ecophysiology of Limonium axillare and Avicennia (2008)

Thanks for your reply ..;) Basically from my readings about mangosteen , it posses apomictic recalcitrant seeds (special seeds) which is insufficient due to its seasonal fruiting and low yieldThanks for your reply ..;) Basically from my readings about mangosteen , it posses apomictic recalcitrant seeds (special seeds) which is insufficient due to its seasonal fruiting and low yield of seeds furthermore conventional vegetative propagation have been commercially unsuccessful because the occurrence of abnormal growth.The application of tissue culture technique could assure the mass production of plantlet compared the conventional way which is involved organogenesis and somatic embryogenesis process. In mangosteen, the exact process for somatic embryogenesis is unknown, even though somatic embryogenesis formed naturally in mangosteen, as the seeds are produced apomictically (no fertilization).Due to this characteristic, the somatic embryogenesis study in mangosteen will be important and interesting, as the characteristic of mangosteen somatic embryogenesis has been little reported in the literature These are my proposal objectives to my supervisor: Objectives of the research: 1. To establish the efficient protocol of Mangosteen’s tissue culture through (i) combination of plant growth regulators and media culture (ii) culture conditions (incubation time, carbon source, gelling agent effect, activated carbon effect) in inducing adventitious shoot (organogenesis) and embryogenic callus of mangosteen 2. To observe the types of callus obtained, by performing histological analysis. 3. To elucidate the molecular biology of somatic embryogenesis in mangosteen through (i) expression of SERK gene during early stage of somatic embryogenesis conducted by using PCR (ii) Suppression Subtractive Hybridization technique (SSH) (iii) genes expression involved in the cDNA library from the SSH technique The question is - Based from my reading, Somatic embryogenesis in Mangosteen successful until the globular stage only.. Why? is there any possibility related to Mangosteen's genetic itself? or its depend on culture condition? or combination and concentration of plant growth regulator?
