The translation initiation factor eIF3M2 upregulates HEAT SHOCK PROTEIN 70 to maintain pollen tube membrane integrity during heat shock.

Pollen germination and pollen tube (PT) growth are extremely sensitive to high temperatures. During heat stress (HS), global translation shuts down and favors the maintenance of the essential cellular proteome for cell viability and protection against protein misfolding. Here, we demonstrate that under normal conditions, the Arabidopsis (Arabidopsis thaliana) eukaryotic translation initiation factor subunit eif3m1/eif3m2 double mutant exhibits poor pollen germination, loss of PT integrity and an increased rate of aborted seeds.

Aim: To assess the acceptability and perceived feasibility of integrating a co-designed nurse-led model of contraception and medication abortion care within rural and regional general practices.
Design: Qualitative exploratory design utilising Sidani and Braden's indicators of acceptability and feasibility.
Methods: We conducted semi-structured interviews with 12 practice nurses, 8 general practitioners and 3 practice managers who currently or previously worked in rural, regional or remote general practice.
ICE1 (Inducer of CBF Expression 1) Is Essential for the Jasmonate-Regulated Development of Stamen in Arabidopsis thaliana.

Floral organ development, pollen germination and pollen tube growth are crucial for plant sexual reproduction. Phytohormones maintain these processes by regulating the expression and activity of various transcription factors. ICE1, a MYC-like bHLH transcription factor, has been revealed to be involved in cold acclimatisation of Arabidopsis.

Heat stress (HS) at the reproductive stage detrimentally affects crop yields and seed quality. However, the molecular mechanisms that protect reproductive processes in plants under HS remain largely unknown. Here, we report that Acetylation Lowers Binding Affinity 3 (ALBA3) is crucial for safeguarding male fertility against HS in Arabidopsis.

Access to abortion is threatened by local, state, and federal government restrictions; limitations on insurance coverage of abortion care; restrictions on funding for training; restrictions imposed by hospitals and health care systems; stigma; violence against health care professionals who provide abortion care; and a subsequent dearth of health care professionals who provide this care. Since the Dobbs v.
