Modern rice cultivars have large panicle but their yield potential is often not fully achieved due to poor grain-filling of late-flowering inferior spikelets (IS). Our earlier work suggested a broad transcriptional reprogramming during grain filling and showed a difference in gene expression between IS and earlier-flowering superior spikelets (SS). However, the links between the abundances of t...
Water deficient stress is one of the major limiting factors of wheat production in arid and semiarid areas of the world such as Iran. Under water deficient stress photosynthesis is limited and remobilization of assimilates stored in stems is more important to grain filling. In order to molecular analysis of fructan remobilization in wheat stem (penultimate) under terminal water deficit stress, ...
Drought stress occurring during the reproductive growth stage leads to considerable reductions in crop production and has become an important limiting factor for food security globally. In order to explore the possible role of drought priming (pre-exposure of the plants to mild drought stress) on the alleviation of a severe drought stress event later in development, wheat plants were subjected ...
Rogers et al., 1996; Fischer et al., 1997). In these plants, enzymes responsible for sucrose uptake and assimilation The original maize (Zea mays L.) var. Zacatecas 58 (Z 0 ) on one side, and photosynthetic rates, sucrose synthesis and five composites of cycles 5, 10, 15, 20, and 23 of and transport on the other, have been described as stratified mass selection (Z 5 , Z 10 , Z 15 , Z 20 , and Z...
Wheat (Triticum aestivum L.) is one of the most important agricultural crops worldwide. However, water is the most important limiting factor for wheat production. This study was initiated to test water stress environmental effects on grain quality and nutritional value of wheat by using single different water conditions at post-anthesis stage. Further analyses were conducted to examine variatio...
Cereal grains accumulate carbohydrates, storage proteins and fatty acids via different pathways during their development. Many genes that participate in nutrient partitioning during grain filling and that affect starch quality have been identified. To understand how the expression of these genes is coordinated during grain development, a genomic approach to surveying the participation and inter...
the experiment was performed to evaluate the morphological, phenological and yield aspects of two different echinochloa species, including barnyardgrass (e. crus-galli) and watergrass (e. orizoides) as a new-introduced weed species. the study was conducted as a 2-years pot-experiment under outdoor condition at rice research institute of iran (rrii) in rasht. the results demonstrated that; time ...
a field experiment was conducted at the seed and plant improvement institute research field station in karaj, iran, during the 2009-10 and 2010-11 growing seasons to estimate genetic progress and the variation in penological and agronomic characteristics in 13 irrigated facultative/winter bread wheat (triticum aestivum l.) cultivars released in iran between 1943 and 2011. trends of temporal var...
in order to determine the best index for evaluating maize genotypes, 15 maize inbred lines were evaluated in two planting dates, 6 july to coincide heat stress with pollination time and 27 july as normal planting to avoid high temperature during pollination and grain filling period, using a randomized complete block design with three replications, in shushtar city, in 2007. result showed that i...
