Phosphorus is the second most important macronutrient after nitrogen and it has many vital functions in the life of plants. Most soils have a low available P content, which has become a key limiting factor for increasing crop production. Also, low P use efficiency (PUE) of crops in conjunction with excessive application of P fertilizers has resulted in serious environmental problems. Thus, dissecting the genetic architecture of crop PUE, mining related quantitative trait loci (QTL) and using molecular breeding methods to improve high PUE germplasm are of great significance and serve as an efficient approach for the development of sustainable agriculture. In this review, molecular and phenotypic characteristics of maize inbred lines with high PUE, related QTL and genes as well as low-P responses are summarized. Based on this, a breeding strategy applying genomic selection as the core, and integrating the existing genetic information and molecular breeding techniques is proposed for breeding high PUE maize inbred lines and hybrids.

GLOBAL GENOMIC PREDICTION IN HORTICULTURAL CROPS: PROMISES, PROGRESS, CHALLENGES AND OUTLOOK
《农业科学与工程前沿(英文)》 2021年 第8卷 第2期
Horticultural crops are a major source of high value nutritious food, and new improved cultivars developed through breeding are required for sustainable production in the face of abiotic and biotic stresses, and to deliver novel, premium products to consumers. However, grower confidence in the performance of new germplasm, particularly across environmental variability, is important for commercial adoption and germplasm-environment matching to optimize production.

Genomic variations in the counterpart normal controls of lung squamous cell carcinomas

Lung squamous cell carcinoma (LUSC) causes approximately 400 000 deaths each year worldwide. The occurrence of LUSC is attributed to exposure to cigarette smoke, which induces the development of numerous genomic abnormalities. However, few studies have investigated the genomic variations that occur only in normal tissues that have been similarly exposed to tobacco smoke as tumor tissues. In this study, we sequenced the whole genomes of three normal lung tissue samples and their paired adjacent squamous cell carcinomas. We then called genomic variations specific to the normal lung tissues through filtering the genomic sequence of the normal lung tissues against that of the paired tumors, the reference human genome, the dbSNP138 common germline variants, and the variations derived from sequencing artifacts. To expand these observations, the whole exome sequences of 478 counterpart normal controls (CNCs) and paired LUSCs of The Cancer Genome Atlas (TCGA) dataset were analyzed. Sixteen genomic variations were called in the three normal lung tissues. These variations were confirmed by Sanger capillary sequencing. A mean of 0.5661 exonic variations/Mb and 7.7887 altered genes per sample were identified in the CNC genome sequences of TCGA. In these CNCs, C:G→T:A transitions, which are the genomic signatures of tobacco carcinogen N-methyl-N-nitro-N-nitrosoguanidine, were the predominant nucleotide changes. Twenty five genes in CNCs had a variation rate that exceeded 2%, including ARSD (18.62%), MUC4 (8.79%), and RBMX (7.11%). CNC variations in CTAGE5 and USP17L7 were associated with the poor prognosis of patients with LUSC. Our results uncovered previously unreported genomic variations in CNCs, rather than LUSCs, that may be involved in the development of LUSC.

The existence of cancer stem cells, stem-like cancer cells (SLCCs), or tumor-initiating cells is considered as the cause of tumor formation and recurrence, indicating the importance of studying novel therapy that targets SLCCs. The origin of SLCCs is controversial because of two competing hypotheses: SLCCs are either transformed from tissue adult stem cells or dedifferentiated from transformed progenitor cells. Our previous research demonstrates that SLCCs are inducible by increasing genomic instability in cancer cells. In this study, to block the emergence of SLCCs, aminoethyl isothiourea (AET), a compound that clears free radicals and is used to protect patients from radioactive exposure, was used as an agent that maintains genomic stability in combination with mitomycin C (MMC), a commonly used chemotherapeutic drug that damages DNA. Using a rabbit tumor model with VX2 hepatic carcinoma, we found that MMC alone increased lung metastases and disadvantaged survival outcome, but the combination of MMC and AET reversed this effect and even prolonged overall survival. Moreover, in a VX2 xenograft model by immunocompromised mice, MMC alone enriched tumor-initiating cells, but the administration of MMC in combination with AET eliminated tumor cells effectively. Furthermore, MMC alone enhanced genomic instability, but MMC combined with AET attenuated the extent of genomic instability in primary VX2 tumor tissue. Taken together, our data suggest that the genomic protector AET can inhibit the induction of SLCCs, and this combination treatment by AET and cytotoxic agents should be considered as a promising strategy for future clinical evaluation.
