objective: apiaceae (umbelliferae) family is one of the biggest plant families on the earth. iran has  a huge diversity of apiaceae members . this family possesses a range of compounds that have many biological activities. the members of this family are well known as vegetables, culinary and medicinal plants. here, we present a review of ethnobotanical uses of apiaceae plants by the iranian peo...

High Plains wheat mosaic virus (HPWMoV, genus Emaravirus) has an octopartite, negative-sense RNA genome, each segment encoding a single open reading frame. The is transmitted by the curl mite (Aceria tosichella) (Tatineni et al., 2014). HPWMoV been reported from Argentina, Australia, Canada, New Zealand, Ukraine and USA (Abdullahi 2020; Snihur 2020). Mixed infections of Wheat streak (WSMV, Trit...

Catalase (CAT) is an antioxidant enzyme that plays a significant role in cellular protection against oxidative damage by degradation of hydrogen peroxide to oxygen and water. In the present study, the complete CAT cDNA sequence of Zostera marina was identified through expressed sequence tags (EST) analysis and the rapid amplification of cDNA ends (RACE) technique. The nucleotide sequence of ZmC...

Phytoliths represent one of the few available altitudinal vegetation proxies for mountain ecosystems. This study analyzed 41 topsoil phytolith samples collected from five altitudinal zones in the southern Himalaya as far as, and beyond, the timberline, from tropical forest (up to 1,000 m a.s.l.) to subtropical forest (1,000-2,000 m a.s.l.), to temperate forest (2,000-3,000 m a.s.l.), to subalpi...

BACKGROUND AND AIMS Oxaziclomefone (OAC), a new herbicide, inhibits cell expansion, especially in roots and cell-cultures of gramineous monocots. OAC does not affect turgor in cultured maize cells, and must therefore inhibit wall-loosening or promote wall-tightening. METHODS The effects of OAC in living cultured maize cells on various biochemical processes thought to influence wall extension ...

BACKGROUND AND AIMS Covalent linkages between xyloglucan and rhamnogalacturonan-I (RG-I) have been reported in the primary cell walls of cultured Rosa cells and may contribute to wall architecture. This study investigated whether this chemical feature is general to angiosperms or whether Rosa is unusual. * METHODS Xyloglucan was alkali-extracted from the walls of l-[1-3H]arabinose-fed suspens...

Rice (Oryza sativa L.) is the only widely cultivated gramineous crops that cannot be infected by rust fungi. To decipher the molecular basis of rice nonhost resistance (NHR) to Puccinia striiformis f. sp. tritici (Pst), the causal agent of wheat stripe rust, proteomic analysis was performed using the two-dimensional electrophoresis (2-DE) technique. The expressed proteins from rice leaves 24 an...

It is difficult to make good quality of silage from alpine gramineous from the Qinghai Tibetan plateau. The effects of lactic acid bacteria (LAB) on the fermentation quality and aerobic stability of Siberian wildrye silage were studied in southeast of the Qinghai Tibetan plateau. Siberian wildrye materials were freshly cut at the sprouting stage, flowering stage, and milky stage. Silage was pre...

Glyamifop (R&D code: FG001), (R)-(2-(4-(6-chlorobenzoxazol-2-oxy) phenoxy) propionyl) glycine ethyl ester is a newly developed aryloxyphenoxypropionate (HRAC Group 1) herbicide for weed control in paddy fields. This work determined the effect of on weeds and its safety rice glasshouse. controlled common gramineous fields at 100 g a.i. ha−1: fresh weight inhibition rates Echinochloa crus-gal...
