Plant regeneration in Curcuma species and assessment of genetic stability of regenerated plants

open access: yesBiologia Plantarum, 2010
An efficient plant regeneration protocol was developed from rhizomes of two Curcuma species C. longa and C. amada. Response was highly dependent on the season, with above 69 % of culture developing adventitious shoots during spring. Greatest regeneration

Microwave treatment induced mutations and altered gene expression in Vigna aconitifolia

open access: yesBiologia Plantarum, 2010
Primary leaf explants of aseptically grown seedlings of moth bean [Vigna aconitifolia (Jacq.) Marechal] immersed in water or not were treated in microwave oven (2450 MHz, 800 W cm-2) for 1, 3, 5 and 7 s before culturing.

Analysis of the genetic diversity of Hepatacodium miconioides at different altitude in Tiantai mountain in Zhejiang Province and its relationship with environmental factors(浙江天台山不同海拔高度七子花种群遗传多样性及其与环境因子的相关性分析)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2005
采用RAPD技术对浙江天台山3个海拔高度的七子花(Heptatcodium miconioides)天然种群的遗传多样性、遗传分化以及与环境因子的相关性进行了研究.12种随机引物在60株个体中共检测到122个可重复的位点.3个种群多态位点百分率为18.85% ~23.77%,平均为21.86%,表明各种群的遗传多样性水平比较低.3个种群Shannon和Nei指数平均为0.132 9、0.092 5,其值较低.虽然3个种群所分布的地理范围小,但种群间存在明显的遗传分化 ...
