Chickpea ( L.) is an important legume crop worldwide. An emerging disease, basal stem rot with obvious wilt symptoms, was observed in the upper part of chickpea plants during the disease survey in Qiubei County of Yunnan Province. Three fungal isolates (ZD36-1, ZD36-2, and ZD36-3) were obtained from the diseased tissue of chickpea plants collected from the field. Those isolates were morphologically found to be similar to . Molecular sequence analyses of multiple gene regions (ITS, , , , and ) indicated that the three isolates showed a high identity with . Pathogenicity and host range tests of the isolates were performed on the original host chickpea and eight other legume crops. The isolates were strongly pathogenic to chickpea and appeared highly pathogenic to soybean, cowpea, and mung bean; moderated or mild pathogenic to adzuki bean and common bean; however, the isolates did not cause symptoms on grass pea (). was previously reported as a main pathogen causing the southern stem canker in soybean. To our knowledge, this is the first report of inducing basal stem rot on chickpea worldwide.

Background: Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial pneumonia with restrictive ventilation. Recently, the structural and functional defects of small airways have received attention in the early pathogenesis of IPF. This study aimed to elucidate the characteristics of small airway epithelial dysfunction in patients with IPF and explore novel therapeutic interventions to impede IPF progression by targeting the dysfunctional small airways.

Skin and hair development is regulated by multitude of programs of activation and silencing of gene expression to maintain normal skin and hair follicle (HF) development, homeostasis, and cycling. Here, we have identified E74-like factor 5 (Elf5) transcription factor, as a novel regulator of keratinocyte proliferation and differentiation processes in skin. Expression analysis has revealed that Elf5 expression was localised and elevated in stem/progenitor cell populations of both the epidermis (basal and suprabasal) and in HF bulge and hair germ stem cell (SCs) compartments during skin and hair development and cycling.

Bone marrow adipose tissue (BMAT) has garnered significant attention due to its critical roles in leukemia pathogenesis, cancer metastasis, and bone marrow failure. BMAT is a metabolically active, distinct tissue that differs from other fat depots. Marrow adipocytes, closely interacting with hematopoietic stem/progenitor cells and osteoblasts, play a pivotal role in regulating their functions.

Intestinal stem cells (ISCs) and Paneth cells (PCs) reside at the bottom of the crypts of Lieberkühn in the small intestine. Recent studies have shown that the transcription factor Mist1, also named BHLHA15, plays an important role in the maturation of PCs. Since there is an intimate interaction between PCs and ISCs, we speculated that the loss of Mist1 could impact these two neighboring cell types.

Immunotherapy utilizes immune cells to target cancer and improves treatment outcomes with few side effects. Despite the effectiveness of immunotherapy, the limited availability of monocytes, which are essential for the differentiation of antigen-presenting cells, remains a major challenge. In this study, we developed a technique for inducing monocytes from hematopoietic stem and progenitor cells by using a serum-free (SF) medium supplemented with optimal concentrations of serum substitutes and cytokines.
