a major portion of the iranian fig (ficus carica) industry is located in high-salinity regions, and salinity is an important limiting factor in the production of this fruit. the present study was conducted to investigate the changes of leaf antioxidant-enzyme activity, proline and total protein content in two fig cultivars with two leaf shapes: ‘anjir sabz’ with lobate and palmate leaves, and ‘...

Background and objectives: Hibiscus sabdariffa L. (roselle) sepals, commonly known as bissap is prepared as a cold drink which is widely drunk in Ghana and across West-Africa for their medicinal and nutritional properties. The plant is known to have anti-hypertensive, anti-hyperlipidemic, anticancer, anti-diabetic and anti-inflammatory activities. For such a widely sol...

The Arabidopsis frill1 (frl1) mutant, that has serrated petals and sepals but no other large changes in plant morphology, was studied. The frl1 had a mutation in STEROL METHYLTRANSFERASE 2 and an altered sterol composition. It was found that the frl1 mutation causes ectopic endoreduplication in petal tips that do not normally endoreduplicate. The rosette leaves of frl1 also showed an enhanced l...

Flavonoids, are a large class of polyphenols, with more than 4000 combinations. They have an antioxidant role in plant photosynthesis and in the human body they optimally act as an antioxidant, anti-inflammatory, anticancer and protector of the heart. Quercetin is in the flavonol group that is used to fight protection specifically against viruses and cancer cells. In this study, Comparison of e...

In this study, the morphology, anatomy, pollen morphology, leaf and seed micromorphology and karyology of the Turkish endangered endemic Physoptychis haussknechtii were investigated in detail for the fi rst time. The species was studied in terms of detailed morphology. Basal leaves are narrowly spatulate and cauline leaves are linear to oblanceolate; both leaves are covered with fl attened stal...

Knotted1-like homeobox (knox) genes are expressed in specific patterns within shoot meristems and play an important role in meristem maintenance. Misexpression of the knox genes, KNAT1 or KNAT2, in Arabidopsis produces a variety of phenotypes, including lobed leaves and ectopic stipules and meristems in the sinus, the region between lobes. We sought to determine the mechanisms that control knox...

Comparative studies help shed light on how the huge diversity in plant forms found in nature has been produced. We use legume species to study developmental differences in inflorescence architecture and flower ontogeny with classical models such as Arabidopsis thaliana or Antirrhinum majus. Whereas genetic control of these processes has been analyzed mostly in pea (Pisum sativum), Medicago trun...
