several attributes that make it attractive as a model species. It has a short seed-to-seed generation time and abundant seed set. Extensive collections of M. truncatula ecotypes — natural geographic variants — exist, and mutant collections are readily produced by physical (fast neutron) and transposonmediated mutagenesis. M. truncatula is also host to Sinorhizobium meliloti, a rhizobium species...
Medicago truncatula is an important model plant for characterization of P deficiency on leguminous plants at the physiological and molecular levels. Growth optimization of this plant with regard to P supply is the first essential step for elucidation of the role of P in regulation of nodulation. Hence, a study was carried out to address the growth pattern of M. truncatula hydroponically grown a...
Gillisia limnaea Van Trappen et al. 2004 is the type species of the genus Gillisia, which is a member of the well characterized family Flavobacteriaceae. The genome of G. limnea R-8282(T) is the first sequenced genome (permanent draft) from a type strain of the genus Gillisia. Here we describe the features of this organism, together with the permanent-draft genome sequence and annotation. The 3...
Short (15 min) and long (1 hour or more) pulses with P32 have been compared at different developmental stages of Limnaea. In short pulses, as opposed to long-pulses, the relative percentage of 4S RNA is at a more or less constant level at all stages of development. Heavy RNA, i. e. heavier than 28S, is traceable with both short and long pulses in the uncleaved and early morula stages. Transcrip...
1. The only cytoplasmic inclusions visible in the living neurone are lipid globules and mitochondria. 2. In both Helix and Limnaea there are three kinds of lipid globules, as follows: (a) large globules, yellowish from their carotinoid content; (6) smaller globules, easily coloured by vital dyes; (c) small globules, not colourable by vital dyes. 3. The crescents and rings ('dictyosomes') seen i...
expressed sequence tags simple sequence repeats (est-ssrs) are important sources for investigation ofgenetic diversity and molecular marker development. similar to genomic ssrs, the est-ssrs are usefulmarkers for many applications in genetics and plant breeding such as genetic diversity analysis, molecularmapping and cross-transferability across related species and genera. in spite of low polym...
بمنظور ارزیابی اثر تنش خشکی بر برخی صفات فیزیولوژیک و مرفولوژیک چهار گونه یونجه یکساله شامل medicago scutellata، m. truncatula، m. rigidula، m. polymorpha، این پژوهش در شرایط آزمایشگاه گلخانه (سال 1374) و مزرعه (سال 1375) به مرحله اجرا درآمد. در شرایط آزمایشگاه، اثر پتانسیلهای خشکی حاصل از پلی اتیلن گلایکول (peg 6000) (-3، -6 و -9 بار) و آب مقطر (صفر بار) بعنوان شاهد بر درصد جوانه زنی، طول ریشه...
Crenate broomrape (Orobanche crenata) is a root parasitic weed that represents a major constraint for grain legume production in Mediterranean and West Asian countries. Medicago truncatula has emerged as an important model plant species for structural and functional genomics. The close phylogenic relationship of M. truncatula with crop legumes increases its value as a resource for understanding...
At the 2nd Medicago meeting (a satellite of the 1999 IS-MPMI meeting in Amsterdam), investigators perceived a need for standardization of genetic nomenclature in Medicago truncatula, due to the rapid growth of research on this species in the past few years. Establishment of such standards grew out of discussions begun at this meeting and continued electronically throughout the M. truncatula com...
