Cotton(Gossypium spp.) is a pivotal crop in the global textile industry, providing essential natural fibers. Additionally, cottonseed offers significant value as a source of oil and as feed for livestock(Huang et al. 2021; Wen et al. 2023). The sector, dependent on cotton, features a comprehensive value chain extending from the processing of fibers to the production of finished textiles, and it employs tens of millions of individuals(Dorward et al. 1970). The vitality of the cotton industry is essential for the economic prosperity of a wide array of interconnected industries. It directly influences the livelihoods of millions of households(Chapman et al. 1972). Therefore, the cotton industry plays a pivotal role in accelerating agriculture modernization.

Senescence is a necessary part of most complex organisms that controlled by many complicated genetic programs. However, unlike animals and humans, leaf senescence has a great impact on nutrient recycling from source to sink to promote reproductive success, thus has strong adaptive advantages in plants. Therefore, from the agricultural point of view, understanding the process of leaf senescence is extremely important for the breeding of higher-yielding crop with optimized nutritional qualities.

【目的】陆地棉（Gossypium hirsutum）的遗传转化技术存在转化周期长、转化效率低等问题，其中，愈伤组织增殖速度慢是导致棉花转化周期长的关键因素。探究陆地棉愈伤组织增殖的最适光照条件，为缩短棉花转化周期提供技术基础。【方法】以陆地棉受体品种WC的下胚轴为外植体诱导愈伤组织，设置红光、蓝光、红蓝光（1﹕1）和白光（CK）4种不同光照处理，研究不同光质下愈伤组织的增殖速度、形态特征，以及相关基因表达水平和相关酶活性的差异，解析光照对愈伤组织增殖的影响并获得最优光照条件。【结果】不同光质对诱导棉花外植体出愈和愈伤组织生长具有明显影响。在4种不同光照处理下，红蓝光相较其他光质具有更显著地促进外植体出愈和愈伤组织增殖的效果，表现为愈伤组织分化时间更短，7—15 d，即与其他处理存在明显表型差异，7 d愈伤组织鲜重红蓝光（0.39 g）>蓝光（0.34 g）>白光（0.24 g）>红光（0.23 g）,15 d时，红蓝光（1.15 g）>蓝光（0.98 g）>白光（0.69 g）>红光（0.51 g），红蓝光照射下的愈伤组织鲜重是白光对照的1.65倍，比单一蓝光或红光照射下的愈伤组织鲜重增加16.5%或125.5%；与此相一致的是，红蓝光处理下，第二周的愈伤增殖率也最高，达14.67%，比红光处理（7.17%）增加1倍多。4种光质下，愈伤增殖及体胚再生相关基因的表达量，红蓝光处理均显示最高。此外，红蓝光处理下愈伤组织的过氧化氢酶（CAT）活性显著提高，活性氧（ROS）含量低于白光对照。【结论】不同光质条件下，棉花外植体的愈伤组织增殖速度不同，红蓝光（1﹕1）促进外植体出愈和愈伤增殖表现最优，其次为蓝光，再次为白光，单独的红光不利于棉花出愈和愈伤增殖。红蓝光（1﹕1）处理诱导光受体及其互作因子、愈伤增殖等相关基因的表达，增强愈伤组织内过氧化氢酶的活性，降低活性氧含量，促进细胞分裂，进而促进愈伤增殖。

Dear Editor Verticillium wilt caused by Verticillium dahliae Kleb. is the most destructive disease in cotton-growing areas around the world. The infection significantly reduces cotton yield and fiber quality due to leaf chlorosis, necrosis or wilting, leaf or boll abscission, and even plant death. The losses may reach up to 80% of lint cotton yield （Wei et al., 2015）.

Due to the capacity to deliver favorable target traits to offspring via breeder selection,backbone parents carrying accumulated favorable agronomic traits have been used widely in breeding programs in crop species,such as rice,wheat,cotton,and maize(Zhou et al.,2016;Fradgley et al.,2019;Li et al.,2019;Ma et al.,2019;Han et al.,2020).It is estimated that 3656(~70%)of the major Chinese rice varieties released from the year 1950e2008 were found to be derived from as few as 35 backbone parents(Tang et al.,2012).Large-scale genome sequencing of diverse rice accessions has been emerged as a promising technology for the identification of key genomic regions or loci under selection during rice domestication(Huang et al.,2012;Wang et al.,2018)and genetic improvement(Xie et al.,2015).On the other hand,sequence information derived from breeding pedigrees could also help to unravel how favorable genomic regions were transmitted from parents to their offspring,as demonstrated by the researches on the pedigrees of the wellknown rice varieties Minghui 63 and Huanghuazhan(Zhou et al.,2016;Chen et al.,2017;Huang et al.,2018).These researches enhanced the understanding of the cumulative effects of beneficial alleles at limited loci in selected offspring varieties.A few examples include IPA1,Gn1a,GW5,GS3,and GS5 for high grain yield,Waxy for good grain eating quality,and Xa21 for high adversity adaptability.
