综述：种子萌发过程中信号感知与传导的分子机制
Molecular mechanisms underlying the signal perception and transduction during seed germination
This review summarizes the current progress in the molecular mechanisms underlying the perception of environmental signals and consequent signal transduction during seed germination, and discuss questions that need to be addressed to better understand the process of seed germination and develop novel strategies for germplasm improvement.
MdSAUR36 的遗传变异参与苹果属中果皮细胞分裂和果实大小的负调控
Genetic variations in MdSAUR36 participate in the negative regulation of mesocarp cell division and fruit size in Malus species
To explore the genetic variations contributing to the phenotype segregation of apple fruit size, anatomic and tranomic analyses were performed in this study by using an interspecific hybrid population between Malus asiatica Nakai and Malus domestica Borkh. cultivars. Then, the functions of the genetic variations were validated by transgenic apple callus. The results could provide new insights into the molecular mechanism of fruit size in Malus species.

通过CsFAD2和CsFAD3基因的过表达提高菜籽油中的亚麻酸含量
Improving linolenic acid content in rapeseed oil by overexpression of CsFAD2 and CsFAD3 genes
With the increasing public attention to the health benefit of polyunsaturated fatty acids (PUFAs) and demand for linolenic acid (C18:3), it is of great significance to increase the C18:3 content in our meal. This study successfully generated rapeseed germplasms with high C18:3 content by simultaneously overexpressing CsFAD2 and CsFAD3, which provides a feasible way for breeding high C18:3 rapeseed cultivars.

水稻谷氨酸脱羧酶 4 (OsGAD4) 中钙调蛋白结合域的截短导致 γ-氨基丁酸的积累并赋予水稻幼苗非生物胁迫耐受性
Truncation of the calmodulin binding domain in rice glutamate decarboxylase 4 (OsGAD4) leads to accumulation of γ-aminobutyric acid and confers abiotic stress tolerance in rice seedlings
OsGAD4 has been reported to exhibit the strongest expression levels during several stress conditions (especially salinity, flooding, and drought) among the five OsGAD genes in the TENOR database. The objective of the study was to produce GABA-enriched and stress-tolerant rice plants by genome editing of the rice GAD4 gene i.e., truncation of Ca2+/CaMBD in the C-terminal region of GAD4 and a subsequent detailed study to explore the response of the mutants upon exposure to adverse conditions.

系统综述：水果和蔬菜作物改良的基因组选择
Genomic selection for crop improvement in fruits and vegetables: a systematic scoping review
This systematic scoping review aims to evaluate the extent of application of GS in fruits and vegetables, focusing on a wide variety of crops with a large array of desirable traits. To this end, our objectives are: 1) To identify the fruit and vegetable crops that have been studied extensively, thereby highlighting the specific crops that may require more research attention; 2) To examine the traits that have been improved through GS, and those that could potentially be benefited from the same approach; 3) To assess the methods involved in GS applications within fruits and vegetables, and, 4) To present findings on how GS studies have been implemented in actual fruit and vegetable breeding strategies.
