The L isomer of (Y , y-diaminobutyric acid is a major component of the polymixin group of antibiotics (1) and of certain Lathyrus peas (24). Some of the polymixins alsocontain~-a:,y-diaminobutyric acid (1). Although the L acid appears to be neurotoxic in rats, it may not be the neurotoxic agent of human lathyrism (4). Except for distribution and toxicity studies in mice (5, 6) and uptake studie...

The research was conducted to determine the effect of different temperatures on germination and early seedling growth grass pea (Lathyrus sativus L.). Two cultivars (Gürbüz-2001, Karadağ) a population (Pop-Diyarbakır) were used as experimental materials. study in complete randomized split-plot design with four replications chamber. rate, mean time, shoot length, root dry weight, fresh weight de...

The intracellular distribution of the neurotoxin 2,4-diaminobutyric acid (DABA) in mature leaves of the perennial legume Lathyrus sylvestris L. var ;Lathco' (flatpea) was determined using subcellular fractions from mesophyll protoplasts. Chloroplasts contained about 15% of the cellular DABA. At least 75% of the DABA was vacuolar, based on the assumptions that each protoplast contained a single ...

Introduction Grasspea (Lathyrus sativus L.) is produced as major crop in Bangladesh, China, India and Pakistan, and to a lesser extent in many countries of Europe, the Middle East, northern Africa, as well as in South America. It is extensively cultivated and naturalised in the Middle East countries of Iraq, Iran, Afghanistan, Syria and Lebanon and in Ethiopia, Egypt, Morocco, Algeria and Libya...

Meiosis is an event of high evolutionary stability that culminates in a reduction of chromosome number. Several abiotic environmental factors such as heat may cause anomalies at genetic level that ultimately impair fertility of the plant. In the present study, the effect of heat stress on various morphological and cytological parameters has been studied in Lathyrus sativus. The most interesting...
