The recent advances in the studies of phototropism are reviewed in this paper:more and more evidences support Bruinsma-Hasagawa hypothesis that tissues within the plant are affected by the Pfr gradient and express growth redistribution; Fluence-response studies of phototropism indicate that fPIPP and TDP are general types of multiple response types of phototropism; several photoreceptors involving phototropism have been characterized; four genetic loci affecting phototropism have been identified by mutants of Arabidopsis thaliana .

本文综述近年来植物向光反应研究方面的进展：（1）植物内部组织感受Pfr梯度引起生长再分布，越来越多的证据支持Bruinsma-Hasagawa假说；（2）光强-反应曲线的研究表明，向光反应存在多种反应类型，其中第一次正向光弯曲和第二次正向光弯曲最为普遍；（3）已鉴定了几种参与向光反应的光受体；（4）通过拟南芥突变体的研究确定了影响向光反应的4个基因。

To examine their function in progressional cell death, we analyzed the cell-death phenotype in cnx-1 and crt-1 mutants.

我们以分析此两基因突变品种上出现之突起透镜状细胞尸体的数量和野生型品种N2比较为方法，来检测它们在细胞死亡过程中的功能。

Further work to purify the mutants and explore their structure and function are in progress.

进一步的纯化和结构功能的鉴定工作正在进行。

So it was considered that the increase of resistant ability in the mutants had no relationship to their rachis structure.

It was found that the positive mutants were obtained within the range of lower doses of 1-5 × 104 Roentgen in shake flask fermentations.

其中产量最高的两株是78-5-49和78-5-52，它们的发酵单位比原始菌株分别提高33.3和28.3％，且这两株菌株都是在10000μg/ml卡那霉素平板中找到的。

Healthy spikes of high-resistant varieties had thicker cell wall and tissue of cortical sclerenchyma, more number of cortical sclerenchyma layers, more number of fibrovascular bundles, smaller area of green subcutaneous tissue in rachis, and theses differences, except number of fibrovascular bundles, enlarged over time. Considering inoculated spikes, cell wall and tissue layers of cortical sclerenchyma displayed different, and to how much extent the relationship between this difference and anti-extension ability of variety had not determined. 6. On the analysis of agronomical characters and molecular marking technology, more than 30 alien anti-Gibberella wheat materials and two mutants coming from this experiment were evaluated their hereditary multiplicity.

实验结果还证明，高抗品种和感病品种的穗轴组织结构确实存在一定差异，在健康穗中，主要表现在高抗品种的皮层厚壁细胞壁和皮层厚壁组织较厚，皮层厚壁细胞层数较多，维管束数目较多，穗轴表皮下绿色组织面积较小，抗、感品种间的差异达显著水平，随发育时间延长，高抗品种的皮层厚壁细胞壁厚度、厚壁组织厚度和厚壁细胞层数增加的幅度较大；在病穗中，主要表现在高抗品种的皮层厚壁组织细胞层数和厚壁细胞壁厚度增加的幅度较大。
