2023/11/30
Multiplex CRISPR-Cas9-based genome editing is an efficient method for targeted disruption of gene function in plants. Use of CRISPR-Cas9 has increased rapidly in recent years and is becoming a routine...
Enabling Breeding Selection for Biomass in Slash Pine Using UAV-Based Imaging
Slash Pine Breeding Selection Biomass
2023/6/2
Background: Traditional methods used to monitor the aboveground biomass (AGB) and belowground biomass (BGB) of slash pine (Pinus elliottii) rely on on-ground measurements, which are time- and cost-con...
Variability in growth and cadmium accumulation capacity among willow hybrids and their parents: implications for yield-based selection of Cd-efficient cultivars（图）
柳树 杂交子代 镉 积累能力
2023/6/2
上个世纪90年代，北美灌木柳育种计划在纽约州启动，经过30多年的杂交、选育以及在美国中、北部的区域试验，选育了一大批高产、高抗的灌木柳栽培品种，目前很多品种在美国已商品化生产。在北美纽约州、宾夕法尼亚州等地，灌木柳被广泛用于工业污染地、垃圾填埋场的植物修复、公路防风雪篱以及生物质能源生产。尽管国际上在柳树重金属污染修复方面做了大量研究，筛选出很多对重金属具有高积累、耐性以及转移的品种，但是重金属积...
