Developing Stable Cultivar through Microspore Mutagenesis in ×Brassicoraphanus koranhort, Inter-Generic Allopolyploid between Brassica rapaand Raphanus sativus

引用

American Journal of Plant Sciences 2017年第6期8卷 1345-1356页

作者： Soo-Seong Lee Byoung Ho Hwang Tae Yoon Kim jeongmin yang Na Rae Han Jongkee Kim Hyun Hee Kim Hadassah Roa Belandres BioBreeding Institute Sillyeong-Ro 153 Daeduk Ansung Gyeonggi Korea Dept. of Integrative Plant Science Chung-Ang University Ansung Korea Plant Biotechnology Institute Department of Life Science Sahmyook University Seoul Korea

A stable progeny was developed through induced mutation, using microspore culture, of the hybrid (F1F1) produced by crossing a newly synthesized, unstable allopolyploid (F1) and a stable cultivar, BB#1(F1) in xBrassicoraphanus. An F1F1 plant was subjected to the induced mutation system established during production of BB#1. Morphological characteristics of the progeny such as color, and leaf number and length, differed from those of BB#1. The bolting time of the progeny in spring cropping was very late compared to BB#1, allowing it to be grown to an adult plant in spring. Genomic in situ hybridization analysis of pollen mother cells at prophase I identified 19 bivalents, 10 from Brassica rapa and 9 from Raphanus sativus. The glucoraphenin content was almost identical to that of BB#1. Two cultivars are available in the baemoochae crop now. These results indicate that induced mutation using microspore culture is a viable method of stabilizing intergeneric allopolyploids between B. rapa and R. sativus.

Reconfigurable physical unclonable cryptographic primitives based on current-induced nanomagnets switching

Science China(Information Sciences) 2022年第2期65卷 188-196页

作者： Shuai ZHANG Jian ZHANG Shihao LI Yaoyuan WANG Zhenjiang CHEN jeongmin HONG Long YOU Wuhan National Laboratory for Optoelectronics and School of Optical and Electronic Information Huazhong University of Science and Technology

Hardware security primitives that preserve secrets are playing a crucial role in the Internet-ofThings(Io T) era. Existing physical unclonable function(PUF) instantiations, exploiting static randomness,generate challenge-response pairings(CRPs) to produce unique security keys that can be used to authenticate devices linked to the Io T. Reconfigurable PUFs(RPUFs) with dynamically refreshable CRPs can enhance the security and robustness of conventional PUFs. The in-plane current-driven perpendicular polarized nanomagnet switching via spin-orbit torque(SOT) possesses great potential for application to memory and logic, as the write-current path is separate from the read-current path, which naturally resolves the write-read interference. However, the stochastic switching of perpendicular magnetization, without an additional symmetry-breaking field, would significantly hinder the technological viability of commercial implementations. Here, we report an initialization-free physical RPUF implemented by SOT-induced stochastic switching of perpendicularly magnetized Ta/Co Fe B/Mg O nanodevices. Using a 15×15 nanomagnet array, we experimentally demonstrate a security primitive that offers a near-ideal 50% uniqueness over 100 reconfiguration cycles, as well as a low correlation coefficient between every two reconfiguration cycles. Our results show that current-induced nanomagnets switching paves the way for developing highly reliable and energy-efficient reconfigurable cryptographic primitives with a smaller footprint.
