Solanaceae, the nightshade family, have ∼2700 species, including important crops potato and tomato, ornamentals, medicinal plants. Several sequenced Solanaceae genomes show evidence for whole-genome duplication (WGD), providing an excellent opportunity to investigate WGD its impacts. Here, we generated 93 transcriptomes/genomes combined them with 87 public datasets, a total of 180 species representing all four subfamilies 14 15 tribes. Nearly 1700 nuclear genes from these...
Summary Mutualisms between plants and fruit‐eating animals were key to the radiation of angiosperms. Still, phylogenetic uncertainties limit our understanding fleshy‐fruit evolution, as in case Solanum , a genus with remarkable diversity, but unresolved relationships. We used 1786 nuclear genes from 247 species, including 122 newly generated transcriptomes/genomes, reconstruct phylogeny examine tempo mode evolution fruit color size. Our analysis resolved backbone providing high support for...
Abstract The Himalayas represent a complex mountain system housing some of the world's richest floras along with high level endemism. Among them, Lysionotus (Gesneriaceae) stands out as small genus (~34 species) that is unexpectedly distributed across southern to eastern Asia. Within this genus, forests south Pan‐Himalaya region emerge hotspot diversity, hosting most epiphytic and endemic species. To explore origin, evolutionary history development current distribution pattern , we inferred...

Tiegh a strain that can efficiently degrade soils. Methods In this study, A. xj was mutated using Atmospheric Room Temperature Plasma (ARTP) technology the strains were screened Mo-Sb Colorimetry with strong P-solubilizing abilities. Results Compared strain, setting treatment time mutagenesis to 120 s, four positive...
We propose and study Complementary Concept Generation (CCGen): given a concept of interest, e.g., "Digital Cameras", generating list complementary concepts, 1) Camera Lenses 2) Batteries 3) Cases 4) Memory Cards 5) Battery Chargers. CCGen is beneficial for various applications like query suggestion item recommendation, especially in the e-commerce domain. To solve CCGen, we to train language models generate ranked lists concepts with two-step training strategy. also teach explanations by...
To accurately predict the spatiotemporal demand for bike sharing, a hybrid model integrating wavelet transform (WT), long short‐term memory (LSTM), and convolutional neural network (CNN) was developed, referred to as WT‐convolutional LSTM (ConvLSTM) model. In this model, Spearman’s rank correlation coefficient employed identify factors influencing within target grid from perspective. After processing historical bike‐sharing order data Shanghai, proposed applied on both working nonworking...
目的本研究旨在对水稻叶片早衰突变体zs进行遗传分析及基因定位，探索水稻叶片早衰的分子机制。 方法从甲基磺酸乙酯（EMS）诱变‘宁粳1号’突变体库中筛选鉴定了1个稳定遗传的早衰突变体zs，构建突变体zs与籼稻品种‘N22’的F2群体，对控制突变性状的基因进行定位，利用RT-qPCR对叶绿素合成以及质体发育相关基因的表达水平进行分析。 结果突变体zs在28℃条件下生长14 d时，zs第2叶叶尖出现黄褐色斑点，并逐渐向叶基部蔓延。突变体zs叶绿素a和叶绿素b含量明显下降。zs叶肉细胞结构异常，叶绿体中类囊体片层结构排列松散。与野生型相比，zs的株高、分蘖数和千粒质量均显著降低。通过构建遗传分离群体，将突变基因定位在第12号染色体短臂上的600 kb的区间内。此区间内含有2个已报道的与叶片衰老相关的基因LOC_Os12g16410和LOC_Os12g16720，分别编码异黄酮还原酶和细胞色素单加氧酶（P450）。测序分析发现，仅在LOC_Os12g16720第2外显子上有1个单碱基突变，导致苏氨酸突变为甲硫氨酸。zs叶绿素合成相关基因和质体发育相关基因的表达量显著低于野生型。...
