A cDNA clone for isocitrate lyase (ICL) was isolated from a cDNA library prepared from the poly(A)+ RNA of etiolated pumpkin cotyledons. The cDNA encoded a polypeptide with 576 amino acids, whose sequence is more than 79% identical to those of ICL from other higher plants and contains the C-terminal tripeptide, Ser-Arg-Met, which is a putative targeting signal to microbodies. Immunogold analysi...

During a survey in 2020, Hormozgan province, the following symptoms were observed zucchini crops growing field: leaf curling, yellow mosaic, swelling of veins young leaves, and shortening internodes. Because importance Tomato Leaf Curl New Delhi Virus (ToLCNDV) other Iran, presence this virus plants was evaluated by PCR amplification coat protein gene. Sequence analysis confirmed ToLCNDV infect...

Drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. To evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. Cultivars with two-level white seedless and khosh...

Background: TRR14 protein is a small member of a multi-gene family in Arabidopsis and is the first ones found during screening of seedlings for their resistant to the trehalose sugar.Objectives: Characterization ofTRR14 over-expressed plants with respect to morphological changes, growth and photosynthesis related parameters.Materials and methods: TRR14gene was isolated from Arabidop...

In Arabidopsis thaliana, the BEL1-like TALE homeodomain protein family consists of 13 members that form heterodimeric complexes with the Class 1 KNOX TALE homeodomain proteins, including SHOOTMERISTEMLESS (STM) and BREVIPEDICELLUS (BP). The BEL1-like protein BELLRINGER (BLR) functions together with STM and BP in the shoot apex to regulate meristem identity and function and to promote correct sh...

In higher plants, photorespiratory Gly oxidation in leaf mitochondria yields ammonium in large amounts. Mitochondrial ammonium must somehow be recovered as glutamate in chloroplasts. As the first step in that recovery, we report glutamine synthetase (GS) activity in highly purified Arabidopsis thaliana mitochondria isolated from light-adapted leaf tissue. Leaf mitochondrial GS activity is furth...
