The copy-number effect of DdS4 perturbation on spore formation, spore viability and doubling time.

Quantitative differences amongst the DdS4 over- and under-expressors in terms of spore forming efficiency, spore viability (estimated on the basis of counting about 5000 spores per experiment for each strain. Mean ± S.D., N = 4) and doubling time (Mean ± S.D., N = 4).DdS4过表达与低表达菌株在孢子形成效率、孢子存活率（通过每个菌株每次实验计数约5000个孢子进行估算，数据以平均值±标准差（Standard Deviation，S.D.）表示，N=4）及倍增时间（数据以平均值±标准差（Standard Deviation，S.D.）表示，N=4）方面的定量差异。
