Overexpression of wheat geneTaMORimproves root system architecture and grain yield inOryza sativa

Abstract: HighlightWheat gene TaMOR is highly conserved in evolution and in wheat improvement, and its overexpression improves root system architecture and grain yield in rice.

“…The recent functional characterization of ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES DOMAIN (AS2/LBD) genes in wheat identified a transcription factor involved in root architecture enhancement. MORE ROOT from the D-genome of wheat (TaMOR-D), an auxin responsive transcription factor in the LBD family, when over-expressed in rice and Arabidopsis resulted in lateral root enhancement in Arabidopsis, and more crown roots, longer panicles and higher grain yield in rice (Li et al, 2016 ). It will be interesting to assess the response of these overexpression lines from Arabidopsis and rice to drought stress.…”

“…Root anatomical features such as, smaller central metaxylem (CMX) vessels and stele area complement RAC875 variety stomatal features by restricting root hydraulic conductivity under stress, another possible mechanism to reduce transpirational loss (Schoppach et al, 2014 ). Deeper roots enhance moisture uptake (Uga et al, 2013 ), whereas transcription factors from LBD gene family improve root architecture (Li et al, 2016 ). Drought tolerant spring wheat cultivars Anmol, Moomal, Bhittai, Sarsabz have smaller stomata size, lower stomatal conductance and are able to maintain higher relative water content under drought stress (Baloch et al, 2013 ).…”

“…The fusion construct (pCAMBIA1300-TaSAP17-D-GFP) and control (pCAMBIA1300-GFP) were transformed into tobacco leaves by Agrobacterium tumefaciens (GV3101)-mediated transformation (Li et al 2016). After an incubation at 25°C for 2 d (16 h/8 h light/dark photoperiod), fluorescence signals were examined using a laser scanning confocal microscope (Leica TCSNT, Germany).…”
