The yield potential of rice is seriously affected by heat stress due to climate change. Since rice is a staple food globally, it is imperative to develop heat-resistant rice varieties. Thus, a thorough understanding of the complex molecular mechanisms underlying heat tolerance and the impact of high temperatures on various critical stages of the crop is needed. Adoption of both conventional and innovative breeding strategies offers a long-term advantage over other methods, such as agronomic practices, to counter heat stress. In this review, we summarize the effects of heat stress, regulatory pathways for heat tolerance, phenotyping strategies, and various breeding methods available for developing heat-tolerant rice. We offer perspectives and knowledge to guide future research endeavors aimed at enhancing the ability of rice to withstand heat stress and ultimately benefit humanity.

Multifunctional Biocompatible Fluorescent <i>Carboxymethyl Cellulose</i>Nanoparticles

引用

Journal of Biomaterials and Nanobiotechnology 2012年第2期3卷 254-261页

作者： ravindran Girija Aswathy Balasubramanian Sivakumar Dhandayudhapani Brahatheeswaran Sreejith Raveendran Tomofumi Ukai Takahiro Fukuda Yasuhiko Yoshida Toru Maekawa Dasappan nair Sakthikumar Bio Nano Electronics Research Center Graduate School of Interdisciplinary New Science Toyo University Kawagoe Saitama JAPAN

A multifunctional nanoparticle based on carboxymethyl cellulose was developed. Folate group was attached to nanoparticle for specific recognition of cancerous cells and 5FU was encapsulated for delivering cytotoxicity. The whole system was able to track by the semiconductor quantum dots that were attached to the nanoparticle. The multifunctional nanoparticle was characterized by UV-VIS spectra, PL spectra, FTIR, TEM, SEM etc and was targeted to human breast cancer cell, MCF7. The biocompatibility of nanoparticle without drug and cytotoxicity rendered by nanoparticle with drug was studied with MCF7 and L929 cell lines. The epifluorescent images suggest that the folate-conjugated nanoparticles were more internalized by folate receptor positive cell line, MCF7 than the noncancerous L929 cells.

关键词： Multifunctional Carboxymethyl Cellulose Folate Nanoparticles Biocompatible

本文叙述了检测火箭固体燃料样品中的杂质,不匀质体、裂纹及夹渣的微波方法。现已证明,采用这种技术可解决样品中缺陷定位和定向问题。由于微波与各种非金属材料的相互作用依赖于材料本身的性质,所以分析传输信号能找到材料内部状态的信息。本文旨在探讨利用微波技术定位火箭燃料中非匀质缺陷(包括金属夹渣、裂纹、未固化及过固化部分)的可能性。就我们所关心的固体燃料来说抗张强度这一重要参数,极大地依赖于燃料的固化状态。

关键词：固体燃料相位夹渣表面缺陷火箭推进剂样品旋转非匀质电磁波微波
