Auxin plays important roles in plant growth and development.Aux/IAA proteins are short-lived transcriptional regulators that interacted with auxin response factor (ARF) and regulate the expression of
Studies that investigated the genetic basis of source and sink related traits have been widely conducted.However,the vascular system that links source and sink received much less attention.When maize
Leaves of C4 crops usually have higher radiation,water and nitrogen use efficiencies compared to the C3 species.Engineering C4 traits into C3 crops has been proposed as one of the most promising ways
Heterosis has been used widely in the breeding of maize and other crops,and plays an important role in increasing yield,improving quality and enhancing stress resistance,but its molecular mechanism is
The ethylene response factor (ERF) plays a key role in the transcriptional regulation of plant growth,development,and response to various environmental perturbations.Studying ERF transcription factors
Melatonin (N-acetyl-5-methoxytryptamine) is a biological hormone involved in many important biological processes,and has an important role in protecting plants against abiotic processes,such as drough
玉米起源于热带和亚热带地区,对温度要求较高,尤其是芽期、苗期和灌浆期对低温非常敏感,这限制了其种植的地理位置.人工驯化和选择使玉米种植延伸到高纬度的寒区地带.近年来,低温灾害呈现频发态势,已成为我国春玉米区最主要的气象灾害之一.培育耐低温品种是提升玉米耐冷能力的有效途径,而挖掘耐冷基因资源是培育耐低温品种的前提和基础.玉米种质资源中存在广泛的遗传变异,蕴藏诸多抗低温材料,这些材料中涉及哪些抗冷性基
Background:The maize genes teosinte glum architecture l (TGA 1) and terminal ear 1 (TE1) are important domestication genes responsible for the dramatic transformations of plant and inflorescence archi
Opaque2 (O2) is a transcription factor that plays important roles during maize endosperm development.Mutation of the O2 gene improves the nutritional value of maize seeds but also confers pleiotropic
We will present recently published research from CIMMYT as a case study to illustrate how LGC offers genomic solutions including plant sampling,DNA extraction and KASP genotyping to accelerate and ena
