Grain size is an important trait influencing both the yield and quality of rice and its major determinant is glume size. However, how glume size is regulated remains largely unknown. Here, we report the characterization of OsKinesin-13A, which regulates cell elongation and glume length in rice. The mutant of OsKinesin-13A, sar1, displayed length reduction in grains and other organs including in...

in order to investigate the effects of foliar application with plant growth promoters on morphological characteristics of maize (single-cross 704), an experiment with three replications and sixteen treatments conducted with priming and spraying of growth promoters (organser, mas-raiz, dulzee and control)  as factorial based on complete randomized block design. analysis of variance showed that t...

Abstract The propagation techniques of robusta coffee by cutting can be accelerated the application plant growth-promoting hormones. This study is to determine efficacy phytohormone-producing isolates on growth two-segment Robusta coffee. was conducted using a non-factorial completely randomized design with 2 replications. treatments consist control, synthetic IBA (Rooton-f) three dilution conc...

Potato ( Solanum tuberosum L.) cultivar IPB CP1 is suitable as a raw material for the potato chip industry. plants are sensitive to various abiotic stresses such drought, aluminium and salinity, which induce reactive oxygen species (ROS). ROS very toxic plant cells. Superoxide dismutase (SOD) one of enzymes that catalyse H2O2 O2. This study aimed establish transgenic cv. containing MmCuZn‐SOD g...

Geminiviruses cause curly top disease, in dicotyledonous plants which constrains host crop production. Beet curly top Iran virus (BCTIV) is a widespread Becurtovirus (family Geminiviridae) in numerous areas within Iran. In this study, we isolated and analyzed a full-length genomic DNA of a new variant of BCTIV from pepper crops in the Kaftark region, east of Shiraz (proposed acronym: BCTIV-Kaf ...

Fast nerve conduction relies on successive myelin segments that electrically isolate axons. Segment geometry-diameter and length-is critical for the optimization of nerve conduction and the molecular mechanisms allowing this optimized geometry are partially known. We show here that peripheral myelin elongation is dynamically regulated by stimulation of YAP (Yes-associated protein) transcription...

Watermelon [Citrullus lanatus (thumb.) Matsum and Nakai] cv. Charleston gray was grafted onto three rootstocks: Cucurbita pepo, Lagenaria siceraria and (Cucurbita maxima x C. moshata). The non grafted watermelon plant was used as control. In this experiment efficiency of two kinds of grafting methods: Tube grafting and Hole insertion grafting and it was found that, Hole insertion grafting gave ...

BACKGROUND Heterogeneity within herbaceous biomass can present important challenges for processing feedstocks to cellulosic biofuels. Alterations to cell wall composition and organization during plant growth represent major contributions to heterogeneity within a single species or cultivar. To address this challenge, the focus of this study was to characterize the relationship between compositi...
